Testing separability of mixed states by looking at them

Research output: Chapter in Book/Report/Conference proceedingConference contribution


By focusing on the X-matrix part of a two-qubit density matrix we provide a lower bound for the concurrence. We then generalize the result and provide an algebraic separability test for a mixed bipartite state of arbitrary dimension.
