冷杂原子分子的Bell型不等式

Bell-type inequalities for cold heteronuclear molecules

Perola Milman, Arne Keller, Eric Charron, Osman Atabek

摘要:

我们引入贝尔型不等式,允许非局域性和纠缠测试与两个冷的异质结分子。所提出的不等式是基于每个分子空间取向之间的相关性,这是一个可以用当今技术实验测量的可观察值。在不同的时间对每个子系统进行定向测量。这些时间在用光子实现的贝尔测试中起偏振器角度的作用。我们讨论了所提出的测试,这也可以适用于其他高维量子角动量系统的实验实现。

英文摘要:

We introduce Bell-type inequalities allowing for non-locality and entanglement tests with two cold heteronuclear molecules. The proposed inequalities are based on correlations between each molecule spatial orientation, an observable which can be experimentally measured with present day technology. Orientation measurements are performed on each subsystem at diferent times. These times play the role of the polarizer angles in Bell tests realized with photons. We discuss the experimental implementations of the proposed tests, which could also be adapted to other high dimensional quantum angular momenta systems.
