Characterization of Josephson phase-slip qubits, Part 2: Annealing

ORAL

Abstract

Josephson phase slip qubits (JPSQs) have been identified as a promising qubit with which to build next-generation quantum annealers. These qubits have charge tunability through the Aharanov-Casher effect. This charge tuning is a signature of their ability to achieve “strong” non-stoquastic XX couplings with “strong” indicating couplings that are large relative to residual single qubit fields. This coupling regime is not known to be possible to achieve with conventional flux qubits. In this talk we present initial characterization measurements of JPSQs that are annealing-compatible and have a large charge dispersion.
