Entanglement evolution of bipartite m?n-dimensional systems

Abstract

Entanglement evolution in high dimensional bipartite systems under dissipation is studied through a lower bound of entanglement of formation. Discontinuities for the time derivative of these quantity are found depending on the initial conditions for entangled states. These abrupt changes along the evolution appear as precursors of entanglement sudden death. © 2007 IOP Publishing Ltd.
