翻译后摘要:我们证明了遍历版本的量子斯泰因引理,这是由Hiai和Petz。结果提供了一个操作和统计解释的量子相对熵作为统计测量的可解释性,并包含作为一个特殊情况的量子版本的香农-麦克米伦定理遍历状态。给出了量子相对渐近均分性质的一种形式。
Abstract:We prove the ergodic version of the quantum Stein’s lemma which was conjectured by Hiai and Petz. The result provides an operational and statistical interpretation of the quantum relative entropy as a statistical measure of distinguishability, and contains as a special case the quantum version of the Shannon-McMillan theorem for ergodic states. A version of the quantum relative Asymptotic Equipartition Property (AEP) is given.
