Ground-State Cooling of a Mechanical Oscillator via a Hybrid Electro-Optomechanical System (2107.00510v1)

Published 1 Jul 2021 in quant-ph, cond-mat.mes-hall, and physics.optics

Abstract: We present a scheme for ground-state cooling of a mechanical resonator by simultaneously coupling it to a superconducting qubit and a cavity field. The Hamiltonian describing the hybrid system dynamics is systematically derived. The cooling process is driven by a red-detuned ac drive on the qubit and a laser drive on the optomechanical cavity. We have investigated cooling in the weak and the strong coupling regimes for both the individual system, i.e., qubit assisted cooling and optomechanical cooling, and compared them with the effective hybrid cooling. It is shown that hybrid cooling is more effective compared to the individual cooling mechanisms, and could be applied in both the resolved and the unresolved sideband regimes.
