Improving measurement protocols for fast readout and high fidelity in a multi-qubit device

ORAL

Abstract

Fast qubit and cavity reset is an integral part of implementing the surface code and performing iterative algorithms. In combination with a Purcell filter and a Josephson Parametric Converter, we optimize cavity parameters and electronics for fast readout and fidelity. With this ability, we present some demonstrations of multi-qubit quantum information processing architectures.
