摘要:

我们提出了一种描述和表征N粒子的状态的方法,该方法原则上可以区分,但由于实验的限制,在实践中无法区分。该技术依赖于一个仔细的治疗之间的交换对称性的状态实验上可访问和实验上不可访问的自由度。我们提出的方法允许一个新的形式化的概念的不可分割性,可以很容易地实现使用目前可用的实验技术。我们的工作是直接相关的量子光学,为此我们提供了一个具体的实施目前的实验。

英文摘要:

We present a method for describing and characterizing the state of N particles that may be distinguishable in principle but not in practice due to experimental limitations. The technique relies upon a careful treatment of the exchange symmetry of the state among experimentally accessible and experimentally inaccessible degrees of freedom. The approach we present allows a new formalisation of the notion of indistinguishability and can be implemented easily using currently available experimental techniques. Our work is of direct relevance to current experiments in quantum optics, for which we provide a specific implementation.
