TY - JOUR ID - 395393 AU - Bouda, Jan - Bůžek, Vladimír PY - 2002 TI - Purification and correlated measurements of bipartite mixed states JF - Physical Review A VL - 65 IS - 03 SP - 034304-1;034304-4 EP - 034304-1;034304-4 PB - American physical society SN - 10502947 KW - quantum information theory KW - entanglement KW - separability KW - factorability N2 - We prove that all purifications of a nonfactorable state (i.e., the state that cannot be expressed in a form $\rho_{AB}=\rho_A\otimes\rho_B$) are entangled. We also show that for any bipartite state there exists a pair of measurements that are correlated on this state if and only if the state is nonfactorable. ER -
