Tuesday Keynote Presentation:
A Quantum Leap in Computing Systems

Dr. Mark B. Ritter, Senior Manager Quantum Science Distinguished Research Staff Member IBM T. J. Watson Research Center

Abstract: An understanding of quantum mechanics, the theory that describes all matter, gave Richard Feynman insight leading to the idea that systems based on quantum technologies could solve problems intractable to von Neumann computing architectures. What are these principles, and how can we use them in a system for advanced computation? A review of quantum technologies and their fragility will set the stage for understanding the engineering complexities of “Noisy Intermediate Scale Quantum” systems (NISQ). We will describe the electrical, packaging, and cryogenic technologies necessary to control and protect the quantum processors, and the conventional control systems and software stack required to orchestrate quantum circuits. We will present examples of quantum chemistry and machine learning algorithms that have been demonstrated on NISQ systems, as well as successful approaches to mitigate errors. Finally, we will show the current estimates of the resource necessary to move beyond the NISQ era to fully fault-tolerant quantum computation, and what that implies about the technology development.

Dr. Ritter Bio: Dr. Ritter is a Distinguished Research Staff Member and senior manager of the Quantum Science group in the Physical Sciences Department at the IBM T.J. Watson Research Center. His group focuses on the experimental and theoretical science of quantum information, especially as applied to quantum computing. The IBM Quantum Experience was launched by his group in May of 2016, allowing users to access and program a five-qubit quantum processor through a GUI-enabled cloud interface. Dr. Ritter received M.S., M.Phil. and Ph.D. degrees in Applied Physics from Yale University in 1987. Dr. Ritter was the recipient of the 1982 American Physical Society Apker Award for his work on the optical and magnetic properties of solids.
