广义量子理论

A Generalized Quantum Theory

Gerd Niestegge

摘要:

在量子力学中,自伴Hilbert空间算符发挥着三重作用,即可观测量、动力学群的生成元和定义混合态的统计算符。人们可能会认为这是希尔伯特空间量子力学的典型特征,但事实并非如此。在基于量子逻辑和条件概率演算(这是吕德斯-冯·诺依曼测量过程的量子逻辑模型)的更一般的理论中,某个有序Banach空间的元素也扮演着同样的三重角色。它显示了正群,自同构群,李代数和统计算子是如何从一个主要假设-三阶干涉的不存在性(三阶干涉及其在量子力学中的不可能性是由R. Sorkin in 1994)。这再次强调了条件概率演算与不存在三阶干扰的假设相结合的力量。在之前的两篇论文中,已经揭示了它对语境性和非定域性的影响。

英文摘要:

In quantum mechanics, the selfadjoint Hilbert space operators play a triple role as observables, generators of the dynamical groups and statistical operators defining the mixed states. One might expect that this is typical of Hilbert space quantum mechanics, but it is not. The same triple role occurs for the elements of a certain ordered Banach space in a much more general theory based upon quantum logics and a conditional probability calculus (which is a quantum logical model of the Lueders-von Neumann measurement process). It is shown how positive groups, automorphism groups, Lie algebras and statistical operators emerge from one major postulate - the non-existence of third-order interference (third-order interference and its impossibility in quantum mechanics were discovered by R. Sorkin in 1994). This again underlines the power of the combination of the conditional probability calculus with the postulate that there is no third-order interference. In two earlier papers, its impact on contextuality and nonlocality had already been revealed.
