Quantum efficiency of binary-outcome detectors of solid-state qubits
arXiv:0806.3614 · doi:10.1103/PhysRevB.78.174512
Abstract
We discuss definitions of the quantum efficiency for binary-outcome qubit detectors with imperfect fidelity, focusing on the subclass of quantum non-demolition detectors. Quantum efficiency is analyzed for several models of detectors, including indirect projective measurement, linear detector in binary-outcome regime, detector of the superconducting phase qubit, and detector based on tunneling into continuum.
