Dynamics of nonlocality for a two-mode squeezed state in a thermal environment
Hyunseok Jeong, Jinhyoung Lee, M. S. Kim · Physical Review A · 2000
We investigate the time evolution of nonlocality for a two-mode squeezed state in a thermal environment. The initial two-mode pure squeezed state is nonlocal with a stronger nonlocality for a larger degree of squeezing. It is found that the larger the degree of initial squeezing, the more rapidly the squeezed state loses its nonlocality. We explain this by the rapid destruction of quantum coherence for the strongly squeezed state.
