Exploring classical correlations in noise to recover quantum information using local filtering
arXiv:2007.12610 · doi:10.1088/1367-2630/ab990c
Abstract
A general quantum channel consisting of a decohering and a filtering element carries one qubit of an entangled photon pair. As we apply a local filter to the other qubit, some mutual quantum information between the two qubits is restored depending on the properties of the noise mixed into the signal. We demonstrate a drastic difference between channels with bit-flip and phase-flip noise and further suggest a scheme for maximal recovery of the quantum information.
