Exploration of potential multi-mode architectures for 3D SRF QPUs

POSTER

Abstract

Decoherence is a key limiting parameter in quantum computing that determines the lifetime of quantum states. Multi-cell superconducting (SRF) cavities with long coherence are promising devices to achieve a large computational quantum volume for a prospective quantum processor based on bosonic qubits. We present preliminary architectural studies and solutions to determine optimal multi-mode devices as quantum processing units (QPUs) via 3D circuit Quantum Electrodynamics (cQED).
