Noise Reduction in Qubit Readout with a Two-Mode Squeezed Interferometer

2022 · Physical Review Applied

Fault-tolerant quantum information processing with flawed qubits and gates requires highly efficient, quantum nondemolition qubit readout. In superconducting circuits, qubit readout using coherent light with fidelity above 99% has been achieved by using quantum limited …
