量子信道的熵传输

On Entropy Transmission for Quantum Channels

Nasir Ganikhodjaev, Farrukh Mukhamedov

摘要:

本文引入了量子信道的熵传输概念,作为Ohya熵的自然推广。这里的量子信道是指$B(H)$到其自身的单位完全正映射(ucp),其中$H$是无限维希尔伯特空间。利用ucp映射的表示定理,我们将每一个ucp映射对应一个唯一确定的状态,并证明了ucp映射的熵小于对应状态的Ohya熵。

英文摘要:

In this paper a notion of entropy transmission of quantum channels is introduced as a natural extension of Ohya's entropy. Here by quantum channel is meant unital completely positive mappings (ucp) of $B(H)$ into itself, where $H$ is an infinite dimensional Hilbert space. Using a representation theorem of ucp mapping we associate to every ucp map a uniquely determined state, and prove that entropy of ucp map is less then Ohya's entropy of the associated state.
