Author(s): Giuseppe D’Auria, Giovanna Morigi, Fabio Anselmi, and Fabio Benatti We propose a novel, feedback-free method to cancel the effects of dephasing in the dynamics of open quantum systems. The protocol makes use of the coupling with an auxiliary system when they are both subjected to the same noisy dynamics in such a way that their interaction leads to cancellation of t… [Phys. Rev.
