    "abstract": "In this letter, we prove that the classical capacity of quantum channel for\n$M$ symmetric states is achieved by an uniform distribution on a priori\nprobabilities. We also investigate non-symmetric cases such as a ternary\namplitude shift keyed signal set and a 16-ary quadrature amplitude modulated\nsignal set in coherent states.",
