    "abstract": "In this paper we fill the gap in previous works by proving the formula for\nentanglement-assisted capacity of quantum channel with additive constraint\n(such as bosonic Gaussian channel). The main tools are the coding theorem for\nclassical-quantum constrained channels and a finite dimensional approximation\nof the input density operators for entanglement-assisted capacity. The new\nversion contains improved formulation of sufficient conditions under which\nsuprema in the capacity formulas are attained.",
