Title: QSPIN: A High Level Java API for Quantum Computing Experimentation

Abstract: QSPIN is a high level Java language API for experimentation in QC models used in the calculation of Ising spin glass ground states and related quadratic unconstrained binary optimization (QUBO) problems. The Java API is intended to facilitate research in advanced QC algorithms such as hybrid quantum-classical solvers, automatic selection of constraint and optimization parameters, and techniques for the correction and mitigation of model and solution errors. QSPIN includes high level solver objects tailored to the D-Wave quantum annealing architecture that implement hybrid quantum-classical algorithms [Booth et al.] for solving large problems on small quantum devices, elimination of variables via roof duality, and classical computing optimization methods such as GPU accelerated simulated annealing and tabu search for comparison. A test suite of documented NP-complete applications ranging from graph coloring, covering, and partitioning to integer programming and scheduling are provided to demonstrate current capabilities.

Jerry Chow, IBM Title: Getting Quantum Ready with Near Term Quantum Processors

Abstract: Quantum computing is a new computational paradigm that is expected to lie beyond the standard model of computation. This implies a quantum computer can solve problems that cannot be solved by a conventional computer with tractable overhead. To fully harness this power we need a universal fault-tolerant quantum computer. However, the overhead in building such a machine is high and a full solution appears to still be many years away. Nevertheless, we believe that we can build machines in the near term that cannot be emulated by a conventional computer. It is then interesting to ask what these can be used for. In this talk we will present IBM’s advances in simulating complex quantum systems with real experimental noisy quantum computers. We will also discuss programming quantum computers over the cloud, and specifically building up a quantum ecosystem via the IBM Q Experience.

Blake Johnson, Rigetti Corp. Title: Parametrically-enabled entangling gates on a multi-qubit lattice

Abstract: An important requirement for scalable quantum computers based on superconducting qubits is the availability of fast entangling gates that maintain good fidelities in a high-connectivity lattice. We discuss a family of such gate operations that are activated by radio-frequency flux pulses applied to tunable transmon qubits. By parametrically modulating the frequency of the transmon, we actuate resonant exchange of excitations with a statically coupled, but otherwise off-resonant, neighboring transmon. The operation is highly selective and does not require mediator qubits or resonator modes, and is therefore ideal for scalable, high-connectivity lattices. In this talk I will discuss the implementation of this gate scheme on an 8-qubit chip.

Sabre Kais, Purdue University Title: “Near term applications of small scale quantum computing for quantum chemistry”

Abstract: The exact solution of the Schrödinger equation for atoms, molecules and extended systems continues to be a “Holy Grail” problem for the field of atomic and molecular physics since inception. Recently, breakthroughs have   been made in the development of hardware-efficient quantum optimizers and coherent Ising machines capable of simulating hundreds of interacting spins through an Ising-type Hamiltonian. One of the most vital questions associated with these new devices is: “Can these machines be used to perform electronic structure calculations?” In this talk I will discuss the possibility of mapping between the electronic structure Hamiltonian and the Ising Hamiltonian and present the simulation results of the transformed Ising Hamiltonian for small molecules such as H2, He2, HeH+,  LiH and H2O. Future directions for scaling up the simulations to larger systems will  be also discussed.

David Keyes, KAUST Title: “A Baseline for Quantum Competitiveness”

Abstract: To project the niches in which quantum computing achieves competitiveness, we need to project forward the capabilities of classical computing – a task that has historically surprised experts in both hardware and algorithms.  Even specifying a suitable metric for comparison is nontrivial, and this talk succeeds at neither.  Its charge is simply to bring the two magisteria into conversation in a workshop that majors in the advances of quantum computing by providing baseline and wishlist for a basket of computations of importance to NASA and similar agencies, from the perspective of such initiatives as DOE’s Scientific Discovery through Advanced Computing and the G-8’s International Exascale Software Project.

Jeremy Levy, Pittsburgh Quantum Institute Title: Simulating Quantum Computers with Correlated Nanoelectronics

Abstract:  Increasing control over quantum mechanical phenomena promises to herald a “second quantum revolution” that will provide new computational resources as well as yield insight into the quantum nature of matter. Despite many impressive early demonstrations, no single physical platform has yet been established. The development of new growth techniques for complex oxides have enabled new families of heterostructures which can be electrostatically gated between insulating, ferromagnetic, conducting and superconducting phases. We are investigating how these phases can be controlled in ways that might be suitable for future quantum technologies. Specifically, we use a conductive AFM probe to “write” and “erase” conducting nanostructures at the LaAlO3/SrTiO3 interface, and probe the resulting electronic phases at millikelvin temperatures. The design process is similar to that of an Etch-a-Sketch toy, but with a resolution of two nanometers, comparable to the spacing between electrons. We are using this precision to “simulate” novel forms of quantum matter with properties that differ significantly from the underlying material. Theoretical frameworks for understanding high-temperature superconductivity (i.e., Hubbard model) might be tested on this hardware platform; alternatively, quantum materials with new and emergent properties could potentially be designed and utilized in a quantum computer (i.e., spin qubit or non-abelian anyon).

 John Martinis, Google Title: Quantum hardware at Google: progress towards exponentially growing computational complexity

Abstract: The quantum-hardware group at Google is building superconducting qubit devices for quantum annealing, quantum simulation and gate-model quantum computing.  A large effort this year is focused on demonstrating quantum supremacy on a 49 qubit device.  Here the output of a quantum computer can only be checked with a large classical supercomputer, which is limited by the memory storage of the 2^49 state space.  I will show experimental data towards this demonstration from a 9 qubit adjustable-coupler “gmon” device, which implements the basic sampling algorithm of supremacy for a computational (Hilbert) space of about 500.  Fidelities in the 90% range indicate that huge Hilbert space computations should be possible with 20-49 qubit devices, which are presently being designed, built and tested.  We have also gone beyond checking whether our quantum computer is operating properly: a quantum-materials simulation shows that complex energy spectra can be accurately predicted on our quantum computer.

Chris Monroe, University of Maryland and IonQ Title: Reconfigurable Quantum Computing with Trapped Ions

Abstract:  Trapped atomic ions are standards for quantum information science, acting as qubits that have unsurpassed levels of quantum coherence, can be replicated and scaled with atomic clock accuracy, and allow near-perfect measurement.  Controllable interactions are mediated by modulating the Coulomb repulsion between ions with control laser beams, allowing the qubit connectivity graph to be reconfigured and optimally adapted to a given algorithm or mode of computing.  Gate fidelities (including measurement) between pairs of qubits in excess of 99.9%, universal and fully-connected control of up to 7 qubits, and quantum simulations with >50 qubits have all been demonstrated in trapped ion systems, and I will speculate on combining all of this into a single universal quantum computing architecture that can be scaled indefinitely with photonic networks.

Biography: Christopher Monroe is a leading atomic physicist and quantum information scientist.  He demonstrated the first quantum gate in any platform at NIST in the 1990s, and at U. Michigan and U. Maryland he discovered new ways to scale trapped ion qubits and simplify their control with semiconductor chip traps, simplified lasers, and photonic interfaces for long-distance entanglement.  He is Co-Founder and Chief Scientist at IonQ in College Park, MD.

Eleanor Rieffel, NASA Ames  Title: A NASA perspective on quantum computing: Opportunities and challenges

Abstract: In the last couple of decades, the world has seen several stunning instances of quantum algorithms that provably outperform the best classical algorithms. For most problems, however, it is currently unknown whether quantum algorithms can provide an advantage, and if so by how much, or how to design quantum algorithms that realize such advantages. Many of the most challenging computational problems arising in the practical world are tackled today by heuristic algorithms that have not been mathematically proven to outperform other approaches but have been shown to be effective empirically. While quantum heuristic algorithms have been proposed, empirical testing becomes possible only as quantum computation hardware is built. The next few years will be exciting as empirical testing of quantum heuristic algorithms becomes more and more feasible. While large-scale universal quantum computers are likely decades away, special-purpose quantum computational hardware has begun to emerge, which will become more powerful over time, as well as small-scale universal quantum computers.

In this talk, I will give an overview of the NASA QuAIL team’s ongoing quantum annealing investigations, with a focus on planning and scheduling, fault diagonosis, and machine learning, as well as its more recent work on gate-model quantum-heuristic algorithms. The talk will conclude with a discussion of research challenges, particularly in optimization and sampling, and of the potential of quantum computing for computational challenges arising in future agency missions.

Martin Roetteler, Microsoft Title: Quantum resource estimates and libraries for computing elliptic curve dlogs

Abstract: We give precise quantum resource estimates for Shor’s algorithm to compute discrete logarithms on elliptic curves over prime fields. The estimates are derived from a simulation of a Toffoli gate network for controlled elliptic curve point addition, implemented in Microsoft’s quantum computing software toolsuite LIQUi|>. We determine circuit implementations for reversible modular arithmetic, including modular addition, multiplication and inversion, as well as reversible elliptic curve point addition. This allows to classically simulate the Toffoli networks corresponding to the controlled elliptic curve point addition as the core piece of Shor’s algorithm for the NIST standard curves P-192, P-224, P-256, P-384 and P-521. The results confirm estimates given earlier by Proos and Zalka and indicate that, for current parameters at comparable classical security levels, the number of qubits required to tackle elliptic curves is less than for attacking RSA, suggesting that indeed elliptic curve cryptography is an easier target than RSA. Based on joint work with Michael Naehrig, Krysta Svore, and Kristin Lauter.

Robert Schoelkopf, Yale University Title: The Prospects for Robust, Modular Quantum Computing with Superconducting Circuits

Abstract: Quantum computation is a completely new and different paradigm for how to store and process information. It offers the possibility of exponential computational advantage for certain types of hard problems, but the hardware for implementing quantum algorithms is still at an early stage. Remarkably, in the last two decades there has been an accumulation of scientific progress that shows that superconducting qubits can perform well enough to actually enable the construction of large scale quantum information systems in the foreseeable future. This also means that one can begin to talk about choice of architectures and algorithms to implement on early quantum machines.

Rolando Somma, Los Alamos National Lab Title: Quantum Algorithms for Turbulent Mixing Simulation

Abstract: Probability density function (PDF) methods have been useful in describing many physical aspects of turbulent mixing. In applications of these methods, modeled PDF transport equations are commonly simulated via classical Monte Carlo techniques, which provide estimates of moments of the PDF at arbitrary accuracy. In this talk, I will describe recently developed techniques in quantum computing and quantum enhanced measurements (quantum metrology) and use them to construct a quantum algorithm that accelerates the computation of such estimates. I will show that the quantum algorithm provides a quadratic speedup over classical Monte Carlo methods in terms of the number of repetitions needed to achieve the desired precision. I will provide a simple illustration of the power of the algorithm by considering a binary scalar mixing process modeled by means of the coalescence/dispersion (C/D) closure.

Jeffrey Yepez, University of Hawaii Title: Quantum computational methods for fluid dynamics

Abstract: An efficient quantum computational model of Navier-Stokes fluid dynamics can be used to emulate classical turbulence.  In this talk I will present the quantum lattice gas model of quantum computation that uses a tensor network constructed over an interconnected parallel array of qubits.  Such a qubit-based quantum system can emulate a Bose-Einstein condensate when it has quantum entanglement confined to local clusters.  Quantum fluids such as Bose-Einstein condensates naturally manifest energy cascades associated with classical fluid turbulence with an emergent inertial range and well defined viscous dissipation scale.  In this talk, I will describe a way to model classical turbulence on a quantum fluid-based quantum computer. Such a quantum computer should outperform upcoming exascale supercomputers for the same task in terms of both computational efficiency and reduced electrical power consumption.
