Effect of thermal environment on quantum nonlocality of superposition of two coherent states (π/2 out of phase)
D. K. Mishra
Abstract
Recently we studied the tests of Bell-type inequalities with superposition of two coherent states (π/2 out of phase) [D. K. Mishra, Acta Phys. Pol. A. 123 , 21 (2013)]. Here, we study the effect of thermal environment on the Bell-CHSH inequality. As the state interacts with the thermal environment, the time evolution of the linear entropy to study the purity loss in the state has also been examined.
