Open Quantum Dynamics: Memory Effects and Superactivation of Backflow of Information
arXiv:2405.11872 · doi:10.3390/math12010037
Abstract
We investigate the divisibility properties of the tensor products of open quantum dynamics with time-dependent generators. These dynamical maps emerge from a compound open system that interacts with its own environment in such a way that memory effects remain when the environment is traced away. This study is motivated by the following intriguing effect: one can have Backflow of Information (BFI) from the environment to without the same phenomenon occurring for either and . We shall refer to this effect as the Superactivation of BFI (SBFI).
