Abstract

Abstract The classification of qubit channels is known since 2002. However, that of rebit channels has never been studies so far, maybe because of the scarcity of concrete rebit examples. In this paper we point out that the strategy used to classify qubit channels cannot be pursued in the rebit case and we propose an alternative which allows us to complete the rebit channel classification. This mathematical result has not only a purely abstract interest: as we shall briefly mention, it may have applications in the analysis of local properties and temporal evolution of real quantum systems and also in a recent color vision model based on quantum information.

rebit量子通道的分类
自2002年以来,人们已经知道了量子比特通道的分类。然而,可能是由于缺乏具体的钢筋混凝土实例,目前尚未对钢筋混凝土通道进行研究。在本文中,我们指出用于分类量子比特信道的策略不能在rebit情况下进行,并提出了一种替代方案,使我们能够完成rebit信道分类。这个数学结果不仅具有纯粹的抽象意义:正如我们将简要提到的,它可以应用于分析真实量子系统的局部特性和时间演化,也可以应用于最近基于量子信息的色觉模型。
