Interview with Christopher Monroe, Gilhuly Family Distinguished Presidential Professor of Physics and Electrical Computer Engineering at Duke University. Monroe discusses his ongoing affiliation with the University of Maryland, and his position as chief scientist and co-founder of IonQ. He discusses the competition to achieve true quantum computing, and what it will look like without yet knowing what the applications will be. Monroe discusses his childhood in suburban Detroit and his decision to go to MIT for college, where he focused on systems engineering and electronic circuits. He explains his decision to pursue atomic physics at the University of Colorado to work under the direction of Carl Wieman on collecting cold atoms from a vapor cell, which he describes as a “zig zag” path to Bose condensation. Monroe discusses his postdoctoral research at NIST where he learned ion trap techniques from Dave Wineland and where he worked with Eric Cornell. He explains how he became interested in quantum computing from this research and why quantum computing’s gestation period is stretching into its third decade. Monroe explains his decision to join the faculty at the University of Michigan, where he focused on pulsed lasers for quantum control of atoms. He describes his interest to transfer to UMD partly to be closer to federal entities that were supporting quantum research and to become involved in the Joint Quantum Institute. Monroe explains the value of quantum computing to encryption and intelligence work, he describes the “architecture” of quantum computing, and he narrates the origins of IonQ and the nature of venture capitalism. He discusses China’s role in advancing quantum computing, and he describes preparations for IonQ to go public in the summer of 2021. At the end of the interview, Monroe discusses the focus of the Duke Quantum Center, and he asserts that no matter how impressive quantum computing can become, computer simulation can never replace observation of the natural world.
