量子理论的经典公式?

A classical formulation of quantum theory?

William F. Braasch, William K. Wootters

摘要:

我们探索一种特殊的方式来重新制定量子理论在经典条款,开始与相空间,而不是希尔伯特空间,并与实际的概率分布,而不是准概率。我们开始的经典图像在认识上是受限制的,在精神上由Spekkens介绍了一个模型。我们得到量子理论只是通过组合一组有限的经典图像。我们在本文中的主要挑战是找到一个简单的方法来描述允许的经典图片集。我们提出了一个很有前途的方法来解决这个问题,并展示了它是如何工作的情况下,一个单一的量子位。

英文摘要:

We explore a particular way of reformulating quantum theory in classical terms, starting with phase space rather than Hilbert space, and with actual probability distributions rather than quasiprobabilities. The classical picture we start with is epistemically restricted, in the spirit of a model introduced by Spekkens. We obtain quantum theory only by combining a collection of restricted classical pictures. Our main challenge in this paper is to find a simple way of characterizing the allowed sets of classical pictures. We present one promising approach to this problem and show how it works out for the case of a single qubit.
