Quantification and manipulation of quantum non-Markovianity
SONG Hong-ting
Abstract：The research of quantum non-Markovianity has rapidly developed and many important theoretical and ex-perimental progresses have been made. In this work, we will mainly introduce two criteria to detect and quantify quantum non-Markovianity from the perspective of quantum mutual information and Fisher information matrix, respectively, and illustrate their basic features through two typical examples. The relationship between them and other approaches is eluci-dated, and a hierarchial aspect of quantum non-Markovianity is revealed. Furthermore, we adopt quantum control method to manipulate this quantum feather, and effectively modify the quantum Markovian dynamics to non-Markovian process.
