    "abstract": "This note presents a simple formula for the average fidelity between a\nunitary quantum gate and a general quantum operation on a qudit, generalizing\nthe formula for qubits found by Bowdrey et al [Phys. Lett. A 294, 258 (2002)].\nThis formula may be useful for experimental determination of average gate\nfidelity. We also give a simplified proof of a formula due to Horodecki et al\n[Phys. Rev. A 60, 1888 (1999)], connecting average gate fidelity to\nentanglement fidelity.",
