Mermin的观察[Phys. Rev. Lett. 65，1838（1990）]，违反本地现实主义的幅度，定义为量子预测和经典约束之间的比率，可以指数增长的系统的大小被证明使用双光子超纠缠态纠缠在偏振和路径自由度，和本地测量偏振和路径的同时。
Mermin's observation [Phys. Rev. Lett. 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 hyperentangled states entangled in polarization and path degrees of freedom, and local measurements of polarization and path simultaneously.
