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 counterexample and point to other factors affecting evolution in mixed states, including classical correlations and entropy.
