Inverse coding theorem for infinite-dimensional quantum channels / A. A. Kuznetsova. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2013. ? 1. P. 32-37 [Moscow Univ. Math. Bulletin. Vol. 68, N 1, 2013.].

In this paper we make a conjecture about the quantum capacity of an infinite-dimensional quantum channel. The proof of the inverse theorem is given based on definitions and properties of the coherent information in the infinite-dimensional case.

Key words: coherent information, quantum channel, quantum capacity.
