A fidelity measure for quantum channels
arXiv:quant-ph/0107108 · doi:10.1016/S0375-9601(01)00640-5
Abstract
We propose a fidelity measure for quantum channels in a straightforward analogy to the corresponding mixed-state fidelity of Jozsa. We describe properties of this fidelity measure and discuss some applications of it to quantum information science.
