Description:
Author(s): Shao-xiong Wu and Chang-shui Yu In this paper, we show that the average three-tangle of the reduced tripartite density matrix for some quadripartite pure states can be increased by some potential measurements on the fourth subsystem, which means this type of quadripartite entanglement can be localized. In particular, we prove that... [Phys. Rev. A 85, 032332] Published Thu Mar 29, 2012
