理想量子Gibbs系综的冯诺伊曼熵和信息率

The von Neumann entropy and information rate for ideal quantum Gibbs ensembles

Oliver Johnson, Yuri Suhov

摘要:

基于理想(自由)粒子(玻色子或费米子)的吉布斯系综,提出了一个量子信息源模型。我们确定(热力学)冯诺伊曼熵的信息率,并建立经典的Lempel-Ziv通用编码算法在Grassberger的形式,这样的源。这将舒马赫定理推广到非IID量子比特的情况。

英文摘要:

A model of a quantum information source is proposed, based on the Gibbs ensemble of ideal (free) particles (bosons or fermions). We identify the (thermodynamic) von Neumann entropy as the information rate and establish the classical Lempel--Ziv universal coding algorithm in Grassberger's form for such a source. This generalises the Schumacher theorem to the case of non-IID qubits.
