Sufficient conditions for a disentanglement
arXiv:quant-ph/9907036 · doi:10.1103/PhysRevA.60.4341
Abstract
We consider a disentanglement process in which local properties of an entangled state are preserved, while the entanglement between the subsystems is erased. Sufficient conditions for a perfect disentanglement (into product states and into separable states) are derived, and connections to the conditions for perfect cloning and for perfect broadcasting are observed.
