Measures of non-Markovianity: Divisibility versus backflow of information
Dariusz Chruściński, Andrzej Kossakowski, ́Angel Rivas · Physical Review A · 2011
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.
