“…Although the mechanical resonator can be coupled to electromagnetic fields at very different wavelengths, most recent experiments use optomechanical couplings from microwave to optical wavelengths. It has been shown both theoretically [38][39][40] and experimentally [41][42][43] that mechanical resonators can be used to convert optical quantum states to microwave ones via optomechanical interactions between a mechanical resonator and a single-mode field of both optical and microwave wavelengths. Hybrid electro-optomechanical systems can exhibit controllable strong Kerr nonlinearities even in the weak- * Electronic address: yuxiliu@mail.tsinghua.edu.cn coupling regime [44].…”

Some optomechanical systems can be transparent to a probe field when a strong driving field is applied. These systems can provide an optomechanical analogue of electromagnetically-induced transparency (EIT). We study the transmission of a probe field through a hybrid optomechanical system consisting of a cavity and a mechanical resonator with a two-level system (qubit). The qubit might be an intrinsic defect inside the mechanical resonator, a superconducting artificial atom, or another two-level system. The mechanical resonator is coupled to the cavity field via radiation pressure and to the qubit via the Jaynes-Cummings interaction. We find that the dressed twolevel system and mechanical phonon can form two sets of three-level systems. Thus, there are two transparency windows in the discussed system. We interpret this effect as an optomechanical analog of two-color EIT (or double-EIT). We demonstrate how to switch between one and two EIT windows by changing the transition frequency of the qubit. We show that the absorption and dispersion of the system are mainly affected by the qubit-phonon coupling strength and the transition frequency of the qubit.

“…Ideally the compliant mirror should merely allow for the conversion between microwave and optical photons so as to avoid unwanted energy losses through mechanical excitations. This suggests exploiting the "polaritonic dark mode"Ĉ = (−G bâ + G ab )/ G 2 a + G 2 b and externally varying G a,b to achieve the adiabatic conversion between the microwave and optical photons free of the mechanical noise [23][24][25][26]. However the realization of a perfect dark mode requires −∆ a = −∆ b = ω m , preventing the extraction of work in the adiabatic conversion.…”

We propose a realization of a quantum heat engine in a hybrid microwave-optomechanical system that is the analog of a classical straight-twin engine. It exploits a pair of polariton modes that operate as out-of-phase quantum Otto cycles. A third polariton mode that is essential in the coupling of the optical and microwave fields is maintained in a quasi-dark mode to suppress disturbances from the mechanical noise. We also find that the fluctuations in the contributions to the total work from the two polariton modes are characterized by quantum correlations that generally lead to a reduction in the extractable work compared to its classical version.

“…In this regard, there has been a growing effort in exploiting the mechanical degrees of freedom to engineer devices such as a microwave-to-optical (or vise versa) frequency converter [1,2] and quantum memory [3,4]. Moreover, quantum mechanical oscillator has been used as an interface to transfer a quantum state from an optical cavity to a microwave cavity [5,6]. Interest in merging optomechanical resonators with solid-state systems has been growing [7]; examples include, ultrastrong optomechanical coupling in GaAl vibrating disk resonator [8,9], cooling of phonons in a semiconductor membrane [10], a strong optomechanical coupling in a vertical-cavity resonator [11], and surface-emitting laser [12].…”

Entanglement between exciton and mechanical modes via dissipation-induced coupling

We analyze the entanglement between two matter modes in a hybrid quantum system consisting of a microcavity, a quantum well, and a mechanical oscillator. Although the exciton mode in the quantum well and the mechanical oscillator are initially uncoupled, their interaction through the microcavity field results in an indirect exciton-mode-mechanical-mode coupling. We show that this coupling is a Fano-Agarwal-type coupling induced by the decay of the exciton and the mechanical modes caused by the leakage of photons through the microcavity to the environment. Using experimental parameters and for slowly varying microcavity field, we show that the generated coupling leads to an exciton-mode-mechanical-mode entanglement. The maximum entanglement is achieved at the avoided level crossing frequency, where the hybridization of the two modes is maximum. The entanglement is also robust against the phonon thermal bath temperature.
