Entanglement and the Speed of Evolution in Mixed States
arXiv:0806.2456 · doi:10.1103/PhysRevA.78.042305
Abstract
Entanglement speeds up evolution of a pure bipartite spin state, in line with the time energy uncertainty. However if the state is mixed this is not necessarily the case. We provide a counter example and point to other factors affecting evolution in mixed states, including classical correlations and entropy.
