Description

We demonstrate that radiation field in mixed thermal or phase-randomized coherent state can be entangled in such a way that Bell inequalities are violated. A counterintuitive result is obtained: a specific test reveals that maximal violation can be achieved with mixed states exhibiting large entropy
