揭示几乎所有quutrit状态中的语境性的实验建议

An experimental proposal for revealing contextuality in almost all qutrit states

Jayne Thompson, Robert Pisarczyk, Pawel Kurzynski, Dagomir Kaszlikowski

摘要:

背景性是量子理论和经典现实主义世界描述之间关键差异的基础现象。在这里,我们提出了一个实验测试,这是能够揭示在所有quutrit系统的上下文,除了完全混合状态,只要我们选择适当的测量基础。三能级系统由单个光子的偏振和空间自由度提供,其中包括三个正交模式。在三维希尔伯特空间中沿射线的投影测量是由线性光学元件和对单模敏感的探测器进行的。我们还讨论了检测器的效率低下和损失的影响,并审查了这项测试的理论基础。

英文摘要:

Contextuality is a foundational phenomenon underlying key differences between quantum theory and classical realistic descriptions of the world. Here we propose an experimental test which is capable of revealing contextuality in all qutrit systems, except the completely mixed state, provided we choose the measurement basis appropriately. The 3-level system is furnished by the polarization and spatial degrees of freedom of a single photon, which encompass three orthogonal modes. Projective measurements along rays in the 3-dimensional Hilbert space are made by linear optical elements and detectors which are sensitive to a single mode. We also discuss the impact of detector inefficiency and losses and review the theoretical foundations of this test.
