On estimating from below for the output entropy of a tensor product of two quantum channels G. G. Amosov Steklov Mathematical Institute of the Russian Academy of Sciences |

Abstract: The notion of a phase-damping channel in infinite dimensional Hilbert space is introduced. It is shown that the decreasing property of the quantum relative entropy allows to estimate from below the output entropy of a tensor product of the phase-damping channel and an arbitrary channel. The connection with the strong superadditivity property for quantum channels is discussed. Language: English |
