产品状态,纠缠和测量

Product states, entanglement, and measurement

Art Hobson

摘要:

复合量子系统AB的乘积态通常被物理解释为子系统A具有性质A1,子系统B具有性质B1。但这种解释与理论和对两个光子动量纠缠态的非局域干涉实验的观察结果相矛盾。这些实验表明,产品状态必须被物理解释为相关性,即产品状态意味着A具有属性A1,当且仅当B具有属性B1。这一澄清解决了确定结果的问题,并随之解决了衡量问题。

英文摘要:

A product state of a composite quantum system AB is customarily interpreted physically to mean subsystem A has property A1 and subsystem B has property B1. But this interpretation contradicts both the theory and observed outcomes of non-local interferometry experiments on the momentum-entangled state of two photons. These experiments demonstrate that product states must be interpreted physically as correlations, i.e. the product state means A has property A1 if and only if B has property B1. This clarification resolves the problem of definite outcomes and, with it, the measurement problem.
