On measures of non-Markovianity: divisibility vs. backflow of information
arXiv:1102.4318 · doi:10.1103/PhysRevA.83.052128
Abstract
We analyze two recently proposed measures of non-Markovianity: one based on the concept of divisibility of the dynamical map and the other one based on distinguishability of quantum states. We provide a toy model to show that these two measures need not agree. In addition, we discuss possible generalizations and intricate relations between these measures.
