Quantitative measures of entanglement in pair-coherent states
G S Agarwal, Asoka Biswas · Journal of Optics B Quantum and Semiclassical Optics · 2005
The pair-coherent states for a two-mode radiation field are known to belong to a family of states with non-Gaussian wavefunction. The nature of quantum entanglement between the two modes and some features of non-classicality are studied for such states. The existing criterion for inseparability are examined in the context of pair-coherent states.
