Universal separability criterion for arbitrary density matrices from causal properties of separable and entangled quantum states
Abstract General physical background of famous Peres–Horodecki positive partial transpose (PH- or PPT-) separability criterion is revealed. Especially, the physical sense of partial transpose operation is shown to be equivalent to what one could call as the “local causality reversal” (LCR-) procedur...
