Quantum efficiency of binary-outcome detectors of solid-state qubits
Alexander N. Korotkov
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 e…

Bell inequality violation versus entanglement in presence of local decoherence
A. G. Kofman, A. N. Korotkov
We analyze the effect of local decoherence of two qubits on their entanglement and the Bell inequality violation. Decoherence is described by Kraus operators, which take into accou…
