R. G. Herb Condensed Matter Seminar
Quantum FM radio for Quantum Computing
Time: 10:00 am
Place: 5310 Chamberlin Hall
Speaker: David Schuster, University of Chicago
Abstract: Individual superconducting qubits have seen impressive improvements in
nearly all aspects over the past decade and now sit at the threshold
of being able to perform quantum error correction. Scaling to larger
numbers of qubits is challenging both in the fundamental aspects of
understanding the behavior of large numbers of strongly coupled qubits
and in the technical aspects of controlling such systems. We take a
unique approach in which we use a superconducting qubit as a quantum
FM radio manipulate individual photons in a array of harmonic
oscillators. This allows control with a single qubit's worth of
classical hardware and simplifies the process of designing and
building large devices. Further, these techniques are compatible with
current brute force scaling efforts and represent a promising avenue
to reach hundreds of qubits in the next several years. In this talk,
I will describe the architecture and show how parametric control can
be used to realize universal quantum logic operations between
arbitrary memory modes
