meQuanics - QSI@UTS Seminar Series - S13 - Tom Stace (University of Queensland)

meet the meQuanics - Quantum Computing Discussions

During this time of lockdown, the centre for quantum software and information (QSI) at the University of Technology Sydney has launched an online seminar series. With talks once or twice a week from leading researchers in the field, meQuanics is supporting this series by mirroring the audio from each talk. I would encourage if you listen to this episode, to visit and subscribe to the UTS:QSI YouTube page to see each of these talks with the associated slides to help it make more sense.

Building a bigger Hilbert space for superconducting devices, one Bloch state at a time.

TITLE: A new kind of qubit SPEAKER: Prof Tom Stace

AFFILIATION: School of Mathematics and Physics, University of Queensland

HOSTED BY: A/Prof. Nathan Langford, UTS Centre for Quantum Software and Information

ABSTRACT: Noise and errors have been the bottlenecks for building robust quantum machines. I will describe a proposed new class of superconducting devices that has built-in error rejection. Fundamentally, the encoding that facilitates this intrinsic robustness comes from the recognition that the Bloch band structure of these systems leads to a much bigger Hilbert spaces than has been traditionally considered. The extra space affords new qubit encodings, which I describe in two different instantiations.
