    Title: A Practical Quantum Programming Workshop

    Abstract: Recent progress on quantum computing hardware, especially in superconducting qubit systems, highlights the need for practical programming models and tools for these first devices. In particular, many near-term applications are quantum/classical hybrid algorithms, that treat the quantum computer as a co-processor. In this workshop, we present an open source quantum programming toolkit targeting near-term applications and devices. This toolkit includes an intermediate quantum instruction language (Quil) and Python libraries for generating and executing Quil code in either a simulated environment or on a quantum processor. This workshop will be interactive, so bring your laptops and Python 2.7 installations!

    Microsoft LIQUi|> – Tuesday, January 17, 8:00pm-9:30pm

    Title: Language Integrated Quantum Operations (LIQUi|>) – A User’s Tutorial

    Abstract: LIQUi|> provides a modular software architecture for the simulation of quantum algorithms. It provides a high-level interface and is independent of a specific quantum architecture. In the past year, we’ve released LIQUi|> to the public for academic use. It is a free package that runs on Windows, Linux and OSX as a provided library and executable with built-in examples and sample scripts as well as a development environment (using Visual Studio or mono, also freely available) that allows the user to compile their own quantum algorithms into an executable. The package includes a 100-page user’s manual as well as over 700 pages of API documentation. This tutorial will focus on:

    • Obtaining and installing the package from http://stationq.github.io/Liquid/
    • Obtaining and installing Visual Studio and mono as development environments (best for attendees to do this beforehand, following instructions on the above website, see “Getting Started”)
    • Getting the system running using built in examples (e.g., Shor)
    • How to draw circuits (e.g., Teleport)
    • Editing, compiling and running your own circuit (step-by-step)
    • Use of scripting (e.g., controlling and creating Quantum Chemistry tests)
    • Overview of documentation (User’s Manual, API docs, Videos, GitHub community)

    To follow along during the tutorial, please download the software from http://stationq.github.io/Liquid/ in advance.

  • Garnet Chan – Simulating quantum systems on classical computers

    Tuesday, January 17, 9:00AM – 10:00AM

    Abstract: I will describe the landscape of classical simulations of the quantum mechanics of materials, chemistry, and biology and the role that quantum information theory has played. I will showcase the current state-of-the-art and highlight challenges, with some speculation as to where quantum computing may be important.

    Chaoyang Lu – Racing classical computers with quantum boson-sampling machines

    Tuesday, January 17, 3:50PM – 4:50PM

    Abstract: In this talk, I will report two routes towards experimental BosonSampling with many photons. We developed SPDC two-photon source with simultaneously a collection efficiency of ~70% and an indistinguishability of ~91% between independent photons. With this, we demonstrate genuine and distillable entanglement of ten photons under different pump power [1]. Such a platform will provide enabling technologies for teleportation of multiple properties of photons [2] and efficient scattershot BosonSampling. Self-assembled InGaAs QDs are in principle deterministic single-quantum emitters with near-unity quantum efficiency and fast decay rate. Using a QD coupled to a micropillar, we produced single photons with high purity, near-unity indistinguishability [3], and high extraction efficiency, all combined in a single device compatibly and simultaneously [4]. Long streams of >1000 single photons separated by tens of microseconds maintain a >92% indistinguishability, which are shown to be near transform limit [5]. The single photons are used for 3-, 4-, and 5-bosonsampling experiments, more than 24,000 times faster than all previous experiments, and more than 10 times faster than through calculating the matrices permanents using the first electronic computer (ENIAC) and transistorized computer (TRADIC) in the human history [6]. Our architecture is feasible to be scaled up to a larger number of photons and with higher rate to race against increasingly advanced classical computers in the near term.

    James Lee – Spectrahedral lifts and quantum learning

    Thursday, January 19, 9:00AM – 10:00AM

    Abstract: Semidefinite programming (SDP) is one of the most powerful general purpose methods in combinatorial optimization, and understanding its strengths and limitations is a central focus of research in mathematical optimization. In joint work with Raghavendra and Steurer, we showed recently that polytopes associated to NP-hard problems (like Max-Cut and the Traveling Salesman Problem) do not admit SDP characterizations of subexponential size. Previously, it was unclear how to achieve such strong lower bounds for any explicit family of polytopes. A key insight involves associating a large quantum-classical state to an SDP and then learning a “simple” approximation to that state via a boosting process guided by the von Neumann entropy. The idea of viewing certain kinds of classical objects as points in a relaxed quantum landscape has other potential applications in the theory of computation.

    Resources: Following are some blog entries about entropy optimization, lifts of polytopes, and related things.

  • Steve Flammia – Debugging the next generation of quantum devices

    Saturday, January 14, 9:30AM – 12:00PM

    Abstract: Recent years have witnessed tremendous progress in laboratory experiments for quantum computing. As the complexity of these experiments increases, however, so too does the difficultly in verifying the quality of the experiment by some objective measure, and in characterizing any undesired noise processes therein so as to improve the next generation devices. In particular, in the absence of a full-fledged quantum computer, we are left with the question: how can we tell if our quantum computer is really working? In this tutorial I will present an overview of the core methods that experimentalists use to address these tasks. The two main tools can be broadly classified as being either tomography or randomized benchmarking, and I will discuss the strengths and weaknesses of these methods. I will describe the theoretical challenges that remain both for mathematical analysis of these ideas as well as for practical data analysis from real experiments.

    Lidia Del Rio – Quantum Thermodynamics

    Saturday, January 14, 2:00PM – 4:30PM

    Abstract: How much heat is dissipated in a quantum computer? Just how small can thermal engines be? When can we model a device’s environment as a heat bath? As technology miniaturizes, we find that traditional thermodynamics is inadequate to study heat and work at the nanoscale, due for example to finite-size effects, emergence of quantum effects, subjectivity of information, and relevance of single-shot results. To tackle these challenges, a new theory of quantum thermodynamics is emerging, drawing insights from quantum information theory. In this tutorial, we will see how tools developed to study entanglement and quantum communication can be applied to thermodynamics. First, we will explore the relationship between information and thermodynamics, from Maxwell’s demon to the work cost of quantum computations. I will then motivate and lay out the resource-theoretic approach to thermodynamics, which allows us to derive the thermodynamic laws from first principles. Finally, I will give a brief overview of the state of the art and promising directions in the field. The tutorial will be accessible to any quantum mechanic with a background in CS, mathematics, or physics.

    Norbert Schuch – Matrix Product States and Tensor Networks

    Sunday, January 15, 9:30AM – 12:00PM

    Abstract: Interacting systems of many quantum particles exhibit rich physics due to their underlying entanglement, and are a topic of major interest in several areas of physics. In recent years, quantum information ideas have allowed us to understand the entanglement structure of such systems, and to come up with novel ways to describe and study them. In my lecture, I will first explain how we can describe such systems based on their entanglement structure, giving rise to so-called Tensor Network States. I will then discuss how these concepts can be used to model strongly interacting many-body systems and to study the different exotic topological states of matter based on their entanglement, and I will briefly highlight their suitability for numerical simulations. Finally, I will discuss open mathematical and physical challenges in the field.

    John Preskill – Quantum Information and Spacetime

    Sunday, January 15, 2:00PM – 4:30PM

    Abstract: I will review how tools from quantum information theory are providing a fresh perspective on some of the deepest problems in particle physics and gravitation. The first lecture will be a brisk overview of the current status of fundamental physics, followed by a discussion of entanglement in quantum field theory and of the properties of quantum black holes. The second lecture will be an introduction to AdS/CFT duality in quantum gravity, emphasizing the emergence of spacetime from entanglement and the role of quantum error correction. I know it sounds scary, but I’m a physicist, so it will be perfectly safe.
