description: It is widely accepted that a quantum computer will need some form of protection against decoherence, and to date the only tool capable of providing fault-tolerance is quantum error correction (QEC). Here we study the interplay of Dynamical decoupling (DD), an open-loop non-fault-tolerant capable decoherence suppression method, and Quantum error correction codes. Several schemes exist where DD is used to improve gate fidelities, such as Dynamically Protected Gates or (Concatenated) Dynamically Corrected Gates. Several authors have combined DD and QEC with different degrees of success, showing improved gate fidelity but at the cost of, in cases strong, extra locality constraints on the error model or a sequence size which is exponential in the number of physical qubits (n). In this work we introduce a dynamical sequences that use as pulses elements of the stabilizer and the normalizer of the QEC code (SXDD sequences). We show how this idea can be adapted to the leading DD schemes: Concatenated DD and Nested Uhrig DD. With this we avoid the need for further locality constraints and obtain shorter sequences while still obtaining fidelity improvements. Moreover, the fact that the SXDD pulses can be chosen to be bitwise allows a natural integration with fault-tolerant methods and the direct porting of several DD schemes for fidelity-enhanced gates into the SXDD scenario.

description: The Achilles' heel of quantum information processors is the fragility of quantum states and processes. Without a method to control imperfection and imprecision of quantum devices, the probability that a quantum computation succeed will decrease exponentially in the number of gates it requires. In the last fifteen years, building on the discovery of quantum error correction, accuracy threshold theorems were proved showing that error can be controlled using a reasonable amount of resources as long as the error rate is smaller than a certain threshold. We thus have a scalable theory describing how to control quantum systems. The next step is to turn this theory into practice. I will give an overview of some of the progress towards the implmentation of quantum error correction around the world with a focus on results since the last Quantum Error Correction conference at USC. I will compare the various achievements and point towards what still need to be done to get robust quantum information processors.

description: Fault-tolerant quantum computation with high threshold in two dimensions Quantum computation is fragile. Exotic quantum states are created in the process, exhibiting entanglement among large number of particles across macroscopic distances. In realistic physical systems, decoherence acts to transform these states into more classical ones, compromising their computational power. However, decoherence can be counteracted by quantum error-correction. In my talk I first give an introduction to fault-tolerant quantum computation in the setting of two-dimensional lattices of qubits in which only nearest neighbors may interact. Such a geometric constraint is, in many physical systems considered for building a large-scale quantum computer, imposed by experimental reality. It is relevant for arrays of superconducting qubits, optical lattices and also for segmented ion traps. Efficient solutions for achieving fault-tolerance in such a scenario are topological. I will review some of the known constructions based on surface codes and color codes.

description: We present and analyze protocols for fault-tolerant quantum computing using color codes. To process these codes, no qubit movement is necessary; nearest-neighbor gates in two spatial dimensions suffices. Our focus is on the color codes defined by the 4.8.8 semiregular lattice, as they provide the best error protection per physical qubit among color codes. We present circuit-level schemes for extracting the error syndrome of these codes fault-tolerantly. We further present an integer-program-based decoding algorithm for identifying the most likely error given the (possibly faulty) syndrome. We simulated our syndrome extraction and decoding algorithms against three physically-motivated noise models using Monte Carlo methods, and used the simulations to estimate the corresponding accuracy thresholds for fault-tolerant quantum error correction. We also used a self-avoiding walk analysis to lower-bound the accuracy threshold for two of these noise models. We present two methods for fault-tolerantly computing with these codes. In the first, many of the operations are transversal and therefore spatially local if two-dimensional arrays of qubits are stacked atop each other. In the second, code deformation techniques are used so that all quantum processing is spatially local in just two dimensions. In both cases, the accuracy threshold for computation is comparable to that for error correction. Our analysis demonstrates that color codes perform slightly better than Kitaev's surface codes when circuit details are ignored. When these details are considered, we estimate that color codes achieve a threshold of 0.082(3)\%, which is higher than the threshold of $1.3 \times 10^{-5}$ achieved by concatenated coding schemes restricted to nearest-neighbor gates in two dimensions [Spedalieri and Roychowdhury, Quant.\ Inf.\ Comp.\ \textbf{9}, 666 (2009)] but lower than the threshold of $0.75\%$ to $1.1\%$ reported for the Kitaev codes subject to the same restrictions [Raussendorf and Harrington, Phys.\ Rev.\ Lett.\ \textbf{98}, 190504 (2007); Wang \etal, Phys. Rev. A \textbf{83}, 020302(R) (2011)]. Finally, because the behavior of our decoder's performance for two of the noise models we consider maps onto an order-disorder phase transition in the three-body random-bond Ising model in 2D and the corresponding random-plaquette gauge model in 3D, our results also answer the Nishimori conjecture for these models in the negative: the statistical-mechanical classical spin systems associated to the 4.8.8 color codes are counterintuitively more ordered at positive temperature than at zero temperature.

description: The entanglement-assisted stabilizer formalism is a generalized form of the stabilizer formalism. This framework allows the code designer to take advantage of a significantly wider range of classical error-correcting codes by using pairs of qubits in a maximally entangled state (or ebits). Low-density parity-check (LDPC) codes are among the best known error-correcting codes in terms of error correction performance and decoding complexity in the classical domain and can also be imported to the quantum domain in a simple manner through the entanglement-assisted stabilizer formalism. From a practical viewpoint, it is desirable to rely on fewer ebits while keeping the error correction ability inherited from classical LDPC codes. We present necessary and sufficient conditions for the existence of quantum LDPC codes consuming only one ebit which are obtainable from pairs of identical LDPC codes, and show relations of entanglement-assisted quantum LDPC codes to some fundamental classes of combinatorial designs.

description: We report examples of local stabilizer codes in 3D that have no string logical operators. Previously known local stabilizer codes in 3D all have string-like logical operators, which make the codes non-self-correcting. We introduce a notion of "logical string segments" to avoid difficulties in defining one dimensional objects in discrete lattices. We prove that every string-like logical operator of our code can be deformed to a disjoint union of short segments, and each segment is in the stabilizer group. The code space dimension depends on the number-theoretic property of the system size.

Our protocol is based on a chain of repeater stations, and exploits topological encoding to tolerate very high levels of defect and error. The repeater stations may employ probabilistic entanglement operations which usually faill; ours is the first protocol to explicitly allow for technologies of this kind. Given a error rate between stations in excess of 10%, arbitrarily long range high fidelity entanglement distribution is possible even if the heralded failure rate within the stations is as high as 99%, providing that unheralded errors are low (order 0.01%).

To this end we characterize the energy landscape of stabilizer code Hamiltonians with local bounded-strength interactions which have a topologically ordered ground state but do not have string-like logical operators. We prove that any sequence of local errors mapping a ground state of such Hamiltonian to an orthogonal ground state must cross an energy barrier growing at least as a logarithm of the lattice size. Our bound on the energy barrier is shown to be tight up to a constant factor for one particular 3D spin Hamiltonian.

description: We study the various overhead costs associated with translating an abstract quantum algorithm to a practical implementation in fault-tolerant, error-corrected quantum hardware. The processes required for quantum error correction can be expensive in terms of quantum resources, and we consider the collective demands of the error correction circuits, distillation of ancilla states, and composition of arbitrary logical gates. To provide a concrete demonstration, we study a quantum computer architecture using surface code error correction, and we examine Shor's algorithm and simulation of quantum chemistry in first-quantized form as typical quantum algorithms for a large-scale quantum computer. As a consequence of this investigation, we can show that practical quantum computers executing these algorithms will require quantum hardware with physical gate operation times of less than 1 microsecond, if the calculation is to complete within 30 days for problems too difficult for existing classical processors.

description: Channel polarization is a phenomenon in which a particular recursive encoding induces a set of synthesized channels from many instances of a memoryless channel, such that a fraction of the synthesized channels become near perfect for data transmission and the other fraction become near useless for this task. The channel polarization effect then leads to a simple scheme for data transmission: send the information bits through the perfect channels and "frozen" bits through the useless ones. One contribution of the present work is to leverage several known results from the quantum information literature to demonstrate that the channel polarization effect takes hold for channels with classical inputs and quantum outputs. We construct linear polar codes based on this effect, and we also demonstrate that a quantum successive cancellation decoder works well, by exploiting Sen's recent "non-commutative union bound" that holds for a sequence of projectors applied to a quantum state. In addition, consider that Mahdavifar and Vardy have recently exploited the channel polarization phenomenon to construct codes that achieve the symmetric private capacity for private data transmission over a degraded wiretap channel. We build on their work and demonstrate how to construct quantum wiretap polar codes that achieve the symmetric private capacity of a degraded quantum wiretap channel with a classical eavesdropper. Due to the Schumacher-Westmoreland correspondence between quantum privacy and quantum coherence, we can construct quantum polar codes by operating these quantum wiretap polar codes in superposition. Our scheme achieves the symmetric coherent information rate for quantum channels that are degradable with a classical environment. This condition on the environment may seem restrictive, but we show that many quantum channels satisfy this criterion, including amplitude damping channels, photon-detected jump channels, dephasing channels, erasure channels, and cloning channels. Our quantum polar coding scheme has the desirable properties of being channel-adapted and symmetric capacity-achieving.

description: We explain how continuous-variable quantum error-correcting codes can be invoked to protect quantum gates in superconducting circuits against thermal and Hamiltonian noise. The gates are executed by turning on and off a tunable Josephson coupling between an LC oscillator and a qubit or pair of quits; assuming perfect qubits, we show that the gate errors are exponentially small when the oscillator's impedance is large in natural units. The protected gates are not computationally universal by themselves, but a scheme for universal fault-tolerant quantum computation can be constructed by combining them with unprotected noisy operations.

description: External controls are necessary to enact quantum logic operations, and the inevitable control noise will result in gate errors in a realistic quantum circuit. We investigate the robustness of quantum gates to the random noise in an optimal control field, by utilizing properties of the quantum control landscape that relates the physical objective (in the present case, the quantum gate fidelity) to the applied controls. An approximate result obtained for the statistical expectation value of the gate fidelity in the weak noise regime is shown to be in excellent agreement with direct Monte Carlo sampling over noise process realizations for fidelity values relevant for practical quantum information processing. Using this approximate result, we demonstrate that maximizing the robustness to additive/multiplicative white noise is equivalent to minimizing the total control time/fluence. Also, a genetic optimization algorithm is used to identify controls with improved robustness to a colored noise characterized by its autocorrelation function.

description: I will describe recent results from an ongoing project which examines the robustness of Kitaev's surface codes, and related FTQC schemes (due to Raussendorf and coworkers) to loss errors. The key insight is that, in a topologically ordered system, the quantum information is encoded in delocalized degrees of freedom that can be "deformed" to avoid missing physical qubits. This allows one to relate error correction and fault tolerance thresholds to percolation thresholds. Furthermore, stabilizer operators can be deformed in a similar way, which means that surface codes retain their robustness to arbitrary types of error, even when significant numbers of qubits are lost. We present numerical evidence, utilizing these insights, to show that: (1) the surface code can tolerate up to 50 percent loss errors, and (2) Raussendorf's FTQC scheme can tolerate up 25 percent loss errors. The numerics indicate both schemes retain good performance when loss and computational errors are simultaneously present. Finally we will describe extensions to other error models, in particular the case where logic gates can fail but in a heralded manner.

description: One of the most interesting challenges in modern physics is to understand, manipulate, and control materials and processes at the level of a single quantum spin. Beside fundamental interest, this research is important for applications ranging from spintronics and information processing to high-precision metrology. Nitrogen-vacancy (NV) impurity centers in diamond have recently emerged as a unique platform for investigating quantum dynamics, decoherence, and quantum control of single spins in solid-state environments. NV centers demonstrate an unusual combination of spin-dependent optical properties, individual addressability, and long spin coherence times. The NV spin state can be manipulated both optically and magnetically, and the quantum control operations can be performed with very high fidelity (>99%). Due to these uniquely favorable properties, quantum dynamics of a single NV spin can be investigated in great detail. I will discuss quantum dynamics of the NV centers, and the decohering effect of the spin bath (made of atomic nitrogen impurities) on the evolution of a NV spin. I will demonstrate how the decoherence dynamics depends on the experimental conditions. Further, I will discuss how the modern techniques of quantum control and dynamical decoupling can be employed to preserve coherence of quantum spins. Using a variety of analytical and numerical tools, we can characterize and optimize the factors which limit controllability. Finally, I will demonstrate how the theoretically optimized protocols for quantum control have been used in order to extend coherence time of individual NV spins, and how dynamical decoupling can be integrated with the gate operation in the prototype hybrid system, the electron-nuclear spin register.

description: Realizing functional, useful quantum computers requires that the research community address both fundamental and practical challenges pertaining to how hardware errors are suppressed to tolerable levels. In this talk I will focus on efforts towards the development of dynamical error suppression as "quantum firmware:" protocols that are designed to suppress hardware errors at the physical level. We introduce an efficient, experiment-friendly filter-design framework for understanding the performance of various pulse sequences, making connections with familiar concepts from electrical engineering and digital signal processing. This perspective allows a concise formulation of known sequence characteristics, but also reveals previously unappreciated practical impacts of system-level constraints. In addition to studying dynamical decoupling, we extend this approach to nontrivial logic gates, providing a simple new technique to calculate and suppress hardware gate error rates. We validate the filter-design approach through experiments using trapped atomic ions as a model quantum system. Our results reveal the performance benefits of optimized dynamical decoupling sequences and demonstrate a technique for sequence optimization through multidimensional search and autonomous feedback.

description: Quantum computers promise to solve certain problems exponentially faster than possible classically but are challenging to build because of their increased susceptibility to errors. Remarkably, however, it is possible to detect and correct errors without destroying coherence by using quantum error correcting codes [1]. The simplest of these are the three-qubit codes, which map a one-qubit state to an entangled three-qubit state and can correct any single phase-flip or bit-flip error of one of the three qubits, depending on the code used [2]. Here we demonstrate both codes in a superconducting circuit by encoding a quantum state as previously shown [3,4], inducing errors on all three qubits with some probability, and decoding the error syndrome by reversing the encoding process. This syndrome is then used as the input to a three-qubit gate which corrects the primary qubit if it was flipped. As the code can recover from a single error on any qubit, the fidelity of this process should decrease only quadratically with error probability. We implement the correcting three-qubit gate, known as a conditional-conditional NOT (CCNot) or Toffoli gate, using an interaction with the third excited state of a single qubit, in 63 ns. We find 85 +/- 1% fidelity to the expected classical action of this gate and 78 +/- 1% fidelity to the ideal quantum process matrix. Using it, we perform a single pass of both quantum bit- and phase-flip error correction with 76 +/- 0.5% process fidelity and demonstrate the predicted first-order insensitivity to errors. Concatenating these two codes and performing them on a nine-qubit device would correct arbitrary single-qubit errors. When combined with recent advances in superconducting qubit coherence times [5,6], this may lead to scalable quantum technology.

Robust Dynamical Decoupling

uk: Комп'ютерні науки

description: Decoherence is among the biggest obstacles for implementing high-performance quantum computing. Possible measures for reducing decoherence include dynamic decoupling (DD), i.e. sequences of inversion pulses applied to the system to be protected. These pulses effectively refocus the interaction between system and environment that drives the coherence decay. For a static environment, they can completely refocus the effect of the environment, resulting in long-lived coherence. We have explored this approach experimentally, using 13C nuclear spins (I=1/2) as the system qubit and a system of coupled 1H nuclear spins as the environment. Our results show that it is possible to extend the coherence time of the system by several orders of magnitude with the help of dynamic decoupling. Care must be taken that the unavoidable imperfections of experimentally realisable rotations do not accumulate throughout the sequence. We therefore designed and tested sequences that compensate the imperfections of the individual pulses over one cycle. The resulting sequences were shown to be very robust and can extend the coherence time of the system by orders of magnitude, independent of the initial state of the system.

description: We explore the fundamental limits on coherence preservation by dynamical decoupling methods in terms of control time scales and the spectrum/bandwidth of the environment. We focus on a decohering qubit controlled by arbitrary sequences of pi pulses. Using results from mathematical analysis, we establish a lower bound for coherence loss in terms of the minimum time between the pulses and the spectral cutoff frequency of the environment. We argue that similar bounds are applicable to a variety of open-loop unitary control methods while we find no explicit dependence of such lower bounds on the total control time. We use these findings to automatically generate "bandwidth adapted dynamical decoupling" sequences that can be used for preserving a qubit up to arbitrary times with the best fidelities theoretically possible given the available control capabilities. We also introduce "Walsh dynamical decoupling" schemes that are optimized for digital sequence generation. Our results imply that fact that, unlike in quantum fault-tolerant architecture, errors cannot be reduced indefinitely using reversible control methods yet a small error can be maintained for a long time.

description: In quantum error correction quantum information is encoded across multiple quantum subsystems in such a way that one can diagnose and fix the most likely errors that occur to the system. This error correcting step is achieved by performing a measurement that does not disturb the encoded quantum information but does diagnose what error has occurred on the system. These error diagnosing measurements are often, but not always, of observables that are non-trivial over nearly the entire quantum system containing the encoded quantum information. The exceptions to this rule are topological and color quantum codes where the diagnosing measurements involve only a small number of spatially local subsystems (that is, involve only measurements over a constant sized neighborhood on some D-dimensional lattice.) These spatially local codes are much better suited to most realistic physical implementations of quantum computers. In this talk I will describe work (joint with Jonathan Shi) that shows how to convert a large class of quantum error correcting codes, all stabilizer codes, into spatially local codes. These codes are subsystem codes derived from measurement based quantum computing and have the same distance and rate as the original code, at the cost of using more qubits. The best of these codes have distances that scale as an area in two out of three spatial dimensions, and have ill-defined distances in the remaining dimension.

description: Atomic ensembles have many potential applications in quantum information science. Owing to collective enhancement, working with ensembles at high densities increases the overall efficiency of quantum operations, but at the same time also increases the collision rate and markedly changes the time dynamics of a stored coherence. We study theoretically and experimentally the coherent dynamics of cold atoms under these conditions. A closed form expression for the spectral line shape is derived for discrete fluctuations in terms of the bare spectrum and the Poisson rate constant of collisions, which deviates from the canonical stochastic theory of Kubo. We measure a prolongation of the coherence times of optically trapped rubidium atoms as their density increases, a phenomenon we call collisional narrowing in analog to the well known motional narrowing effect in NMR. We explain under what circumstances collisional narrowing can be transformed into collisional broadening. On account of collisions, conventional echo techniques fail to suppress this dephasing, and multi-pulse dynamical decoupling sequences are required. We present experiments demonstrating a 20-fold increase of the coherence time when a sequence with more than 200 pi pulses is applied. We perform quantum process tomography and demonstrate that using the decoupling scheme a dense ensemble with an optical depth of >200 can be used as an atomic memory with coherence times exceeding 3 sec. Further optimization requires utilizing specific features of the collisional bath, which we measure directly.

These highly desirable features come at the cost of high classical processing complexity. We show how to perform the processing associated with an n by n lattice of qubits, each being manipulated fault-tolerantly, in O(n^2) average time per QEC round. We describe how to parallelize the algorithm to O(1), using constant computing resources per unit area and local communication. Both complexities are optimal.

While original DCG constructions rely on fully analytical control design and aim to maximize portability with respect to the underlying error model, realistic applications may call for DCG sequences that are both more efficient and more flexible in accommodating control constraints. After reviewing the standard DCG framework, I will show by example how numerical optimization methods can be successfully applied to this end. In particular, I will address a practically motivated scenario where the presence of an always-on drift Hamiltonian mandates numeric search in order to allow robust gate synthesis.

Ausgehend von politischen Fragen im Zusammenhang mit der eben erfolgten Wahl erforschen sie, was das Gesprächsformat für sie selbst bedeutet. Ihre Gäste nehmen den Ball mit Interesse auf.

Podcast first?

description: Drei neue Podcasts in einem Jahr. Ende 2016 startete PULS ein Storytelling-Experiment: den Doku-Podcast "Einfach Machen", einen Podcast über Menschen, die das tun, was sie wirklich wollen. Anfang 2017 legten Schacht & Wasabi los: Im Podcast über deutschen Rap unterhalten sich die beiden HipHop-Journalisten über die Themen, Trends und Tweets der Deutschrap-Blase. Und im Oktober kam "Im Namen der Hose – der Sexpodcast von PULS" dazu, in dem Ariane Alter und Linda Becker offen über die "Oh ja!" und die "Oh no!"-Momente im Bett reden. Denn wer Bescheid weiß, hat mehr Spaß. Viel Podcast-Stoff für eine halbe Stunde Vortag also – auf den Punkt gebracht: 5 Dinge, die ich in einem Jahr übers Podcastmachen bei einem Radiosender gelernt habe – von Produktion, über Ansprache und Vermarktung bis hin zur Frage, wann es Sinn haben kann, einen Podcast auf YouTube zu veröffentlichen.

Sprechend Denken

uk: Комп'ютерні науки

description: Die gängige Bezeichnung dafür ist Laberpodcast - das wird dem Genre aber nicht zwingend gerecht. Wir fragen, ob denken im Sprechen anderes ermöglicht, als denken im Schreiben, oder schweigend zu denken... Und haben da so eine These: Denn im sprechenden Denken ergeben sich - für uns - mitunter ganz neue Perspektiven. Es werden Standpunkte erörtert, Argumente gesammelt - bisweilen sogar eine neue Streit- oder Diskussionskultur etabliert. Dabei ist es egal, wie banal das Thema zunächst scheint. Wir wollen ein Plädoyer für den Laberpodcast halten und erörtern: Was passiert eigentlich, wenn wir sprechend denken? Ob alleine, wie im Fall von Moritz Klenk - oder gemeinsam, wie im Fall vom Was denkst du denn? Podcast oder vom Sendegarten mit Martin Rützler.

description: Zuerst stand da die Idee, zum G20-Gipfel nach Hamburg zu fahren. Dann stand da die Erkenntnis, dass ich zu wenig Erfahrungen von solchen Ereignissen habe. Und dann stand da plötzlich ein Podcast-Konzept, das mich über vier Folgen begleiten sollte: Zuhörenden etwas über eigene Erlebnisse zu berichten und die Möglichkeit, sich auch als Demo-Neuling zurecht zu finden. Nach dem G20-Gipfel in Hamburg wurde mir klar, dass genau die Punkte, die mich zuerst zweifeln ließen ob ein Podcast zur Berichterstattung taugt, genau die Punkte sind, die ich mit der Erfahrung aus Hamburg als positiv bewerte. So war ich zum Beispiel nicht "gezwungen" in den Kanon der Polizeitweets einzustimmen und die PR-Arbeit mit Pressearbeit zu verwechseln. Das Podcasten nach einer Demonstration in einem ruhigen Umfeld bietet all denen Schutz, die sich ebenfalls auf dieser Demo befinden. Audio hat den Vorteil, kein Bildmaterial ins Netz zu blasen (Foto und Video). Mit etwas eigener Disziplin was andere Beteiligte an Demonstrationen angeht, war es möglich, vier Folgen lang keine Namen oder Orte zu nennen, an denen sich andere Personen aufgehalten haben. Es bleibt in Zukunft wichtig – und könnte sogar noch wichtiger werden (weitere Verschärfungen des Demonstrationsrechts sind geplant) – über Demonstrationen und Ereignisse wie den G20-Gipfel zu berichten.

Diese durften mit einer Anschubfinanzierung jeweils einen Dummy zu ihrem Konzept produzieren, alle Dummy-Episoden sind auf www.callforpodcast.de weiterhin parat zum Anhören. Die drei Gewinner "Ein Mann für Mama", "Fakecast" und "Was bisher geschah" haben mit dem Bayerischen Rundfunk Gespräche über eine gemeinsame Produktion geführt. "Ein Mann für Mama" wird vom Notizbuch auf Bayern2 produziert und wird im November 2017 starten, der "Fakecast" wird im Januar 2018 durch das Medienmagazin auf B5 veröffentlicht.

en: Law, Economics and Social Sciences

description: In this paper the representation of the knowledge base of firms, research organizations or fields of knowledge as a network will be described. Networks of this type have nodes constituted by units of knowledge defined at a given level of aggregation and links determined by the interactions of such units. Examples of such units are the technological classes associated to patents or the themes that can be identified in scientific publications or patents. The paper will describe the application of this approach to the dynamics of knowledge in firms, research organizations or fields of knowledge by mapping the changes occurring in the structure of knowledge and by measuring some relevant properties of the of the knowledge bases, such as their coherence, variety or cognitive distance. Among other applications this approach can allow us to detect the presence of knowledge discontinuities, such as technological paradigms, and their impact on the behaviour of firms or research organizations.

description: The goal of machine learning is to enable computers to learn and excel at performing specific tasks. Examples of these tasks range from driving a car and recognizing a face in a picture, to improving a web search. It has also been argued that, through machine learning, we can get closer to achieving the overarching goal of human-level Artificial Intelligence (AI). In the future, machine learning will play a signigficant role in many industries and institutions. This symposium will feature keynote presentations and discussions across a variety of topics at the frontier of machine learning and AI.

description: Many companies that integrate Ember into their stacks often have a hard time finding quality developers in an ever-changing job market. Because of this, we often resort to training new developers in-house on the ways of Ember and Glimmer. Yet, what is the most effective way for us to hire, teach, and train developers in this aspect? I want to offer some practical advice, stories, and lessons learned from my experience with this over the past few years.

Living Animation

uk: Комп'ютерні науки

description: Most animation on the web is canned, non-interactive, and inflexible. It doesn’t dynamically adjust itself to changing conditions and user interactions. It’s expensive to create and maintain because the programmer or designer is trying to micromanage the motion. It needs to be hand-tuned for each new feature, device, or media query breakpoint. There is an alternative: we can think more like game designers. We can build robust, dynamic systems that animate gracefully, with clear separation between app logic and app motion.

Creating forms isn’t always the most exciting part of development and, at times, it may seem daunting. Fear not! I’d like to talk through some pain points of building an important piece of user interface: we will discuss what to do, what not to do, and which Ember addons have come to the rescue.

Prying Open the Black Box

description: When your code doesn't work the way you expect, it could be a frustrating exercise to figure out what exactly went wrong. In this session, we will walk through the process of debugging an Ember app. Along the way, we will learn about some of the tools and techniques that could help shed light on the behavior of our code. Finally, we will also take a brief tour into the Ember codebase to look for clues. Upon completing this orientation, you will be well-equipped to pry open the mysterious black box the next time your app misbehaves!

The Future of Data in Ember

uk: Комп'ютерні науки

description: This talk will provide an overview of the latest developments in the realm of managing data in Ember applications. The focus will be the past, present, and future of Ember Data, which is becoming faster, lighter-weight, and more modular. The JSON:API specification, which provides the conventions that underpin Ember Data, is evolving through “operations” and other extensions. And new interfaces are being explored in Ember Data to allow interop with Orbit.js, which will unlock capabilities such as offline operation, store forking / merging, and more. This talk will also touch upon some popular data management solutions in the wider JavaScript ecosystem, both to show how they can be used in Ember applications and to compare and contrast them with Ember’s conventional data stack.

description: Ember is "the framework for building ambitious applications." But what happens when that ambition leaves some users behind? For many in the enterprise environment, accessibility is a legal requirement. For anyone building a new app elsewhere, the user data speaks for itself: nearly 10% of all users have some sort of a disability. So how can we make this easier? What already exists? Not only will we discuss how Ember supports this, we'll look at some imaging techniques being used in scientific research that may help us look at this challenge from a different angle.

Building a Memex in Ember

uk: Комп'ютерні науки

description: In 1945, the Memex was proposed as the ultimate personal library. In addition to storing information, users could navigate, organize, link, and share data with others. Tragically, zero of these devices were ever produced, but 72 years later, I’ve build my own Memex in Ember. I’ve created dozens of importers for different services, organized the 10M+ data points into a graph schema, and built a frontend with Ember. Almost all aspects of my personal history is available through this app. I’ll go over the history of the Memex, how I used Ember to build my own, and demo what I can do with it.
