Creation of Entanglement with Nonlocal Operations
Yong Zhang, Cao Wan-Cang, Gui‐Lu Long · Communications in Theoretical Physics · 2005
We discuss how to create more entanglement with nonlocal operations acting on two-particle states. For a given nonlocal operation, we find that some input states cannot produce entanglement and some produce the maximal entanglement, and find that any initial entangled states can produce more entanglement than initial product states.
