无限维希尔伯特空间的方程、状态和格

Equations, States, and Lattices of Infinite-Dimensional Hilbert Spaces

Norman D. Megill, Mladen Pavicic

摘要:

本文给出了关于量子态空间、无穷维Hilbert空间的子空间格、无穷维Hilbert空间方程以及它们之间的联系的几个新结果。特别地,我们得到了一个n元广义正交多项式方程,它在任意无穷维Hilbert空间都成立.然后,我们加强Godowski的结果表明,在正交格上的强状态定义的Godowski方程以及正交模举行。我们还证明了文献中提出的所有6-和4-变量orthogonesian方程可以分别简化为新的4-和3-变量方程,并且Mayet的例子来自Godowski方程。为了在测试这些庞大的方程方面取得突破,我们设计了几种新颖的算法,用于生成具有任意数量的块和原子的Greechie图(目前测试最多50个),并自动检查它们上的方程。本文提出了一种从Hilbert格出发,在不引入状态概念的情况下,通过几个附加条件得到复无穷维Hilbert空间的方法。可能的影响的结果量子计算问题进行了讨论。

英文摘要:

We provide several new results on quantum state space, on lattice of subspaces of an infinite dimensional Hilbert space, and on infinite dimensional Hilbert space equations as well as on connections between them. In particular we obtain an n-variable generalized orthoarguesian equation which holds in any infinite dimensional Hilbert space. Then we strengthen Godowski's result by showing that in an ortholattice on which strong states are defined Godowski's equations as well as the orthomodularity hold. We also prove that all 6- and 4-variable orthoarguesian equations presented in the literature can be reduced to new 4- and 3-variable ones, respectively and that Mayet's examples follow from Godowski's equations. To make a breakthrough in testing these massive equations we designed several novel algorithms for generating Greechie diagrams with an arbitrary number of blocks and atoms (currently testing with up to 50) and for automated checking of equations on them. A way of obtaining complex infinite dimensional Hilbert space from the Hilbert lattice equipped with several additional conditions and without invoking the notion of state is presented. Possible repercussions of the results to quantum computing problems are discussed.
