Distillation of quantum non-Markovianity
arXiv:2308.05867 · doi:10.1016/j.physleta.2024.129582
Abstract
Non-Markovianty of open quantum systems dynamics is a physically relevant property which is usually associated with the backflow of (quantum) information. Using this paradigmatic marker, we develop an operational framework to investigate how non-Markovianity for qubit dynamics can be distilled when many copies of the channels are used, possibly allowing for a stronger effect on the backflow of information.
