作为量子信息的量子力学(以及更多)

Quantum Mechanics as Quantum Information (and only a little more)

Christopher A. Fuchs

摘要:

在本文中,我再次试图引起一些善意的麻烦。问题仍然是,我们什么时候才能停止用专门讨论量子基础的会议来加重纳税人的负担?有人表示怀疑,除非找到一种方法,把量子理论简化为两三个具有明确物理意义(而不是抽象的、公理化的)的陈述,否则看不到尽头。在这方面,没有什么工具比量子信息理论更适合直接攻击。这种方法并不是将最新的时尚勉强应用于一个由来已久的问题,它之所以有希望,正是因为量子理论的大部分(但不是全部)结构总是与信息有关。只是物理学界需要提醒。本文虽然以quant-ph/0106166为核心,但纠正了一个错误,并提供了几个超出前一版本的观察结果。特别是,我确定了量子力学的一个元素,我不会在理论中标记一个主观术语-它是整数参数D传统上归因于量子系统通过其希尔伯特空间维度。

英文摘要:

In this paper, I try once again to cause some good-natured trouble. The issue remains, when will we ever stop burdening the taxpayer with conferences devoted to the quantum foundations? The suspicion is expressed that no end will be in sight until a means is found to reduce quantum theory to two or three statements of crisp physical (rather than abstract, axiomatic) significance. In this regard, no tool appears better calibrated for a direct assault than quantum information theory. Far from a strained application of the latest fad to a time-honored problem, this method holds promise precisely because a large part--but not all--of the structure of quantum theory has always concerned information. It is just that the physics community needs reminding. This paper, though taking quant-ph/0106166 as its core, corrects one mistake and offers several observations beyond the previous version. In particular, I identify one element of quantum mechanics that I would not label a subjective term in the theory--it is the integer parameter D traditionally ascribed to a quantum system via its Hilbert-space dimension.
