Dissipation as a resource in circuit quantum electromechanics

László Dániel Tóth

A primary challenge in quantum science and technology is to isolate the fragile quantum states from their environment in order to prevent the irreversible leakage of energy and information which causes decoherence. In the late 1990s, however, a new paradig ...
