Measures of non-Markovianity: Divisibility versus backflow of information

Year: 2011

Type: article

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 model to show that these two measures need not agree. In addition, we discuss possible generalizations and intricate relations between these measures.
