Invariance of separability probability over reduced states in 4x4 bipartite systems [PDF]
, 2017 The geometric separability probability of composite quantum systems is extensively studied in the last decades. One of most simple but strikingly difficult problem is to compute the separability probability of qubit-qubit and rebit-rebit quantum states ...
