Abstract
We propose a fidelity measure for quantum channels in a straightforward ana logy to the corresponding mixed-state fidelity of Jozsa. We describe proper ties of this fidelity measure and discuss some applications of it to quantu m information science. (C) 2001 Elsevier Science B.V. All rights reserved.
