Interplay of dissipative and coherent processes in engineered quantum systems — •Anja Metelmann — Free University Berlin, Berlin, Germany

The concept of dissipation engineering has enriched the methods available for state preparation, dissipative quantum computing and quantum information processing. Combining such engineered dissipative processes with coherent dynamics allows for new effects to emerge. For example, we found that any factorisable (coherent) Hamiltonian interaction can be rendered nonreciprocal if balanced with the corresponding dissipative interaction. In this talk, we illustrate the basic recipe on how to realize nonreciprocity via reservoir engineering, and show that the dissipative process by itself can yield a purely unitary evolution on one subsystem.
