量子超纠缠增强Einstein-Podolsky-Rosen局域实在论的破坏

Enhancing the Violation of the Einstein-Podolsky-Rosen Local Realism by Quantum Hyper-entanglement

Marco Barbieri, Francesco De Martini, Paolo Mataloni, Giuseppe Vallone, Adán Cabello

摘要:

Mermin的观察[Phys. Rev. Lett. { \bf 65},1838(1990)]的结果表明,对局域实在论的破坏(定义为量子预言与经典束缚之间的比值)的大小可以随着系统的大小呈指数增长,这一结果是利用在偏振自由度和路径自由度上纠缠的双光子超纠缠态以及同时对偏振和路径的局域测量来证明的。

英文摘要:

Mermin's observation [Phys. Rev. Lett. {\bf 65}, 1838 (1990)] that the magnitude of the violation of local realism, defined as the ratio between the quantum prediction and the classical bound, can grow exponentially with the size of the system is demonstrated using two-photon hyper-entangled states entangled in polarization and path degrees of freedom, and local measurements of polarization and path simultaneously.
