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…
On the multiplicativity conjecture for quantum channels
G. G. Amosov, A. S. Holevo
A multiplicativity conjecture for quantum communication channels is formulated, validity of which for the values of parameter close to 1 is related to the solution of the funda…
On some additivity problems in quantum information theory
G. G. Amosov, A. S. Holevo, R. F. Werner
A class of problems in quantum information theory, having an elementary formulation but still resisting solution, concerns the additivity properties of various quantities character…
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…
