Coherences of transmon qubits embedded in superconducting whispering gallery mode resonators

ORAL

Abstract

We describe the design and measurement of a planar uperconducting two-resonator one-qubit device. The two resonators are realized in a hardware-efficient way by the differential modes of a superconducting whispering gallery mode resonator [APL 103, 142604]. This device forms an integrated basis for a quantum memory [New J. Phys. 16, 045014 2014].
