Abstract: Developing a large-scale quantum information processor has become a major industrial challenge over the last few years. Of the many quantum systems available to tackle this challenge, superconducting circuits have shown impressive results thus far and appear to be posed to scale up rapidly. In this presentation, I will discuss some of the materials challenges associated with developing superconducting circuits for large scale quantum information processors. This includes providing a basic introduction to superconducting qubits, their fabrication, measurement, and coupled operations. I will then explore some of the emerging opportunities for improving, connecting, and expanding these systems for processing quantum information. In particular, I will highlight some of the efforts at the National Institute of Standards & Technology in Boulder, Colorado, USA.
Dr. Raymond W. Simmonds received his B.A. (1995), M.S. (1999), and Ph.D. (2002) in Physics from the University of California, Berkeley. From 2002 to 2004, Dr. Simmonds held an NRC Postdoctoral Fellowship with Dr. John Martinis at NIST, Boulder, developing coupled superconducting phase qubits. Dr. Simmonds joined the NIST faculty as a Physicist in 2004 and was Project Leader from 2012 to 2014. He currently conducts research in the Advanced Microwave Photonics Group in the Applied Physics Division of the Physical Measurement Laboratory (PML) at NIST, Boulder, focusing on developing Quantum Information Technology with superconducting circuits. His research is centered on the application of microwave techniques at low temperatures to enable the control and measurement of quantum information for simulations or computing.
