The optimal unitary dilation for bosonic Gaussian channels
Filippo Caruso, Jens Eisert, Vittorio Giovannetti +1
A generic quantum channel can be represented in terms of a unitary interaction between the information-carrying system and a noisy environment. Here, the minimal number of quantum…
Generalized minimal output entropy conjecture for one-mode Gaussian channels: definitions and some exact results
V. Giovannetti, A. S. Holevo, S. Lloyd +1
A formulation of the generalized minimal output entropy conjecture for Gaussian channels is presented. It asserts that, for states with fixed input entropy, the minimal value of th…
Mutual and coherent informations for infinite-dimensional quantum channels
A. S. Holevo, M. E. Shirokov
The work is devoted to study of quantum mutual information and coherent information -- the two important characteristics of quantum communication channel. Appropriate definitions o…
On the Choi-Jamiolkowski Correspondence in Infinite Dimensions
A. S. Holevo
We give a mathematical formulation for the Choi-Jamiolkowski (CJ) correspondence in the infinite-dimensional case in the form close to one used in quantum information theory. We sh…
The entropy gain of infinite-dimensional quantum channels
A. S. Holevo
In the present paper we study the entropy gain for infinite-dimensional channels . We show that unlike finite-dimensional case where the minimal entropy gain is a…
