Environment-enabled ground-state cooling of resonators

Achieving ground-state cooling of resonators is a prerequisite for many experiments and applications, including ultra-precise sensing and quantum information processing. Due to the unavoidable interaction of resonators with their environment, reaching the ground state is often challenging. To address this issue, we present a scheme for achieving simultaneous cooling of multiple resonators to their quantum ground state, which is otherwise difficult to achieve. In contrast to traditional laser cooling schemes that rely on coherence to reduce a resonator's motion to its ground state, our approach employs incoherent thermal sources to achieve the same aim.
