非锐化观测量EPR Bell检验与相对论量子测量

EPR-Bell Tests with Unsharp Observables and Relativistic Quantum Measurement

P. Busch

摘要:

在这方面的贡献,我将审查分析的爱因斯坦波多尔斯基罗森的论点,贝尔不等式和相关的实验自旋的积极运营商价值的措施。具体来说,我将探讨Clauser-Horne-Shimony-Holt不等式和观测量的一个基本\emph{classicality}性质--观测量的\emph{coexistence}之间的关系。贝尔不等式的推导unsharp自旋将给出以下重建Mittelstaedt和Stachow的原始EPR参数。在这方面,我们讨论了需要一个一致的相对论性描述的局部测量,在空间扩展的,纠缠系统的时空中的类空分离区域进行。

英文摘要:

In this contribution I will review the analysis of the Einstein-Podolsky-Rosen argument, Bell's inequalities and of associated experiments for spins in terms of positive operator valued measures. Specifically, I will explore the relation between the Clauser-Horne-Shimony-Holt inequality and a fundamental \emph{classicality} property of observables -- their \emph{coexistence}. A derivation of Bell's inequalities for unsharp spins will be given which follows a reconstruction by Mittelstaedt and Stachow of the original EPR argument. In this context we discuss the need for a consistent relativistic description of localised measurements, carried out in spacelike separated regions of spacetime on spatially extended, entangled systems.
