Some aspects of separability
arXiv:quant-ph/0112177 · doi:10.1016/S0375-9601(02)00279-7
Abstract
We present three necessary separability criteria for bipartite mixed states, the violation of each of these conditions is a sufficient condition for entanglement. Some ideas on the issue of finding a necessary and sufficient criterion of separability are also discussed.
