    "abstract": "Two observations are given on the fidelity of schemes for quantum information\nprocessing. In the first one, we show that the fidelity of a symplectic\n(stabilizer) code, if properly defined, exactly equals the `probability\u0027 of the\ncorrectable errors for general quantum channels. The second observation states\nthat for any coding rate below the quantum capacity, exponential convergence of\nthe fidelity of some codes to unity is possible.",
