    "abstract": "The necessary and sufficient conditions of optimality of the decoding of\nquantum signals minimizing the Bayesian risk are generalized for the Shannon\nmutual information criteria. It is shown that for a linear channel with\nGaussian boson noise these conditions are satisfied by coherent\nquasi-measurement of the canonical annihilation amplitudes in the received\nsuperposition.",
