Abrupt Changes in the Dynamics of Quantum Disentanglement
arXiv:quant-ph/0702246 · doi:10.1103/PhysRevA.75.062324
Abstract
Entanglement evolution in high dimensional bipartite systems under dissipation is studied. Discontinuities for the time derivative of the lower bound of entanglement of formation is found depending on the initial conditions for entangled states. This abrupt changes along the evolution appears as precursors of entanglement sudden death.
