Abstract
We derive a lower bound for the concurrence of mixed bipartite quantum states, valid in arbitrary dimensions. As a corollary, a weaker, purely algebraic estimate is found, which detects mixed entangled states with a positive partial transpose.Year: 2004 PMID： 15169261 DOI： 10.1103/PhysRevLett.92.167902
