Circuit QED with multi-pole microwave cavity filters

ORAL

Abstract

Circuit QED has proven to be a successful architecture for quantum computing and quantum optics. In this architecture multiple superconducting qubits are coupled to a high-Q microwave resonator, allowing for control, coupling and readout of qubit states. However, as we scale to larger systems and longer coherence times, reducing residual couplings become more important. We discuss multi-pole cavity filters as isolating elements between qubits, used as a technique for producing improved gates.
