Measurement of Planar Fluxonia

ORAL

Abstract

Superconducting qubits are a promising approach to realizing quantum computers. One challenge to this realization is the finite coherence times of these qubits. Fluxonium, with its long coherence times, is a promising qubit modality to use to build up such a quantum processor. Here we measure various fluxonia of different circuit parameters and geometries, characterizing the coherence and single qubit gate fidelities of planar aluminum on silicon designs.
