Biography

Dr. David Awschalom is the Liew Family Professor and Vice Dean of the Pritzker School for Molecular Engineering at the University of Chicago, a Senior Scientist at Argonne National Laboratory, and Director of the Chicago Quantum Exchange. He is also the inaugural director of Q-NEXT, one of the US Department of Energy Quantum Information Science Research Centers. Before arriving in Chicago, he was the Director of the California NanoSystems Institute and Professor of Physics, Electrical and Computer Engineering at the University of California – Santa Barbara, and previously a Research Staff Member and Manager at the IBM Watson Research Center. He works in spintronics and quantum information engineering, studying the quantum states of electrons, nuclei, and photons in semiconductors and molecules for quantum information processing. Awschalom received the APS Oliver Buckley Prize and Julius Edgar Lilienfeld Prize, the EPS Europhysics Prize, the MRS David Turnbull Award and Outstanding Investigator Prize, the AAAS Newcomb Cleveland Prize, the International Magnetism Prize from the International Union of Pure and Applied Physics, and an IBM Outstanding Innovation Award. He is a member of the American Academy of Arts & Sciences, the National Academy of Science, the National Academy of Engineering, and the European Academy of Sciences.

Abstract

Traditional electronics are rapidly approaching the length scale of atoms and molecules: the latest computer chips in development include transistors the size of a single strand of DNA.  In this regime, a single atom out of place can have outsized negative consequences and so scaling down classical technologies requires ever-more perfect control of materials.  Surprisingly, one of the most promising pathways out of this conundrum may emerge from current efforts to embrace these atomic ‘defects’ to construct devices that enable new information processing, communication, and sensing technologies based on the quantum nature of electrons and atomic nuclei. In addition to their charge, the property of electrons used in classical computing, individual defects in semiconductors and molecules possess an electronic spin state that can be employed as a quantum bit.  These qubits can be manipulated and read using a simple combination of light and microwaves with a built-in optical interface and retain their quantum properties over millisecond to second timescales. With these foundations in hand, we discuss emerging opportunities and the importance of national quantum research centers to collaborate with industry and atomically-engineer qubits for nuclear memories, entangled registers, sensors and networks for science and technology.
