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.
