Fast and high-fidelity dispersive readout of a spin qubit with squeezed microwave and resonator nonlinearity
Abstract Fast and high-fidelity qubit measurement is essential for quantum error correction in universal quantum computing. This study examines dispersive measurement of a spin in a semiconductor double quantum dot using a nonlinear microwave resonator. By employing displaced squeezed vacuum states,...
