Indirect control of the asymptotic states of a dynamical semigroup (original) (raw)

This paper investigates the potential for modifying the stationary states of a quantum system evolving under a quantum dynamical semigroup by incorporating an auxiliary system. By enlarging the original system to include this ancillary system and analyzing their joint evolution, the researchers explore how the correlations between the two systems influence the stationary states of the original system. The work reveals various scenarios in which these stationary states can be affected, providing both theoretical insights and practical examples for quantum control applications.
