Random access quantum information processing in multimode cavities 1

ORAL

Abstract

Multimode cavities are a promising resource for quantum information and simulation, due to their large Hilbert space, restricted set of decoherence channels, and large single-photon lifetimes. We describe the design of a novel seamless superconducting multimode cavity with a tailored mode spectrum and single-photon lifetimes on the order of a millisecond. Universal quantum control of the modes of the cavity is performed using a superconducting transmon circuit, realizing a random access quantum information processor [1] in a 3D architecture. We construct quantum gates using sideband transitions with the transmon and characterize their fidelities.
