Entanglement dynamics under local Lindblad evolution
Sandeep K. Goyal, Sibasish Ghosh · arXiv (Cornell University) · 2010
The phenomenon of entanglement sudden death (ESD) in finite dimensional composite open systems is described here for both bi-partite as well as multipartite cases, where individual subsystems undergo Lindblad type heat bath evolution. ESD is found to be generic for non-zero temperature of the bath. At T=0, one-sided action of the heat bath on pure entangled states of two qubits does not show ESD.
