Additivity for transpose depolarizing channels
Nilanjana Datta, Alexander S. Holevo, Yuri Suhov
Additivity of the minimal output entropy for the family of transpose depolarizing channels introduced by Fannes et al. [quant-ph/0410195] is considered. It is shown that using the…
Remarks on the classical capacity of quantum channel
A. S. Holevo
A direct proof of the relation between the one-shot classical capacity and the minimal output entropy for covariant quantum channels is suggested. The structure of covariant channe…
Evaluating capacities of Bosonic Gaussian channels
A. S. Holevo, R. F. Werner
We show how to compute or at least to estimate various capacity-related quantities for Bosonic Gaussian channels. Among these are the coherent information, the entanglement assiste…
Sending Quantum Information with Gaussian States
Alexander S. Holevo
Quantum information characteristics, such as quantum mutual information, loss, noise and coherent information are explicitly calculated for Bosonic attenuation/amplification channe…
Coding Theorems for Quantum Communication Channels
A. S. Holevo
The more than thirty years old issue of the information capacity of quantum communication channels was dramatically clarified during the last period, when a number of direct quantu…
On Quantum Communication Channels with Constrained Inputs
A. S. Holevo
The purpose of this work is to extend the result of previous papers quant-ph/9611023, quant-ph/9703013 to quantum channels with additive constraints onto the input signal, by showi…
