Universal separability criterion for arbitrary density matrices from causal properties of separable and entangled quantum states

no code implementations17 Dec 2020 Gleb A. Skorobagatko

In particular, for the family of such EC-density matrices it has been found that there exists a number of $ N $- and $ D $-dependent separability (or entanglement) thresholds $ p_{th}(N, D) $ which in the case of a qubit-pair density matrix in $ \mathcal{H}_{2} \otimes \mathcal{H}_{2} $ Hilbert space are shown to reduce to well-known results obtained earlier by Peres [5] and Horodecki [6].
