A fidelity measure for quantum channels

Research output: Contribution to journalArticlepeer-review


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.
