摘要:

我们研究了在含光学参量放大器(OPA)的旋转激子-光力学系统(EOMS)中非互易的双粒子和三粒子纠缠。我们证明在实验可行的参数下,光子、激子和声子之间的非互易纠缠可以实现。我们发现由萨格纳克效应引起的非互易纠缠可通过OPA调节。特别地,我们显示OPA显著增强了光子-激子纠缠和三粒子纠缠,但削弱了光子-声子和激子-声子纠缠。此外,我们发现光子-激子非互易纠缠不仅可以在室温甚至更高温度下生成,而且对谐振腔损耗具有高度鲁棒性。我们的工作为操控室温非互易纠缠开辟了道路,这可能对开发非互易量子技术有所帮助。

英文摘要:

We study nonreciprocal bipartite and tripartite entanglement in a spinning exciton-optomechanical system (EOMS) with an optical parametric amplifier (OPA). We demonstrate that nonreciprocal entanglement among photons, excitons, and phonons can be achieved under experimentally feasible parameters. We find that the nonreciprocal entanglement induced by Sagnac effects can be regulated through the OPA. Particularly, We show that the OPA significantly enhances photon-exciton entanglement and tripartite entanglement but weakens photon-phonon and exciton-phonon entanglement. Moreover, we find that the photon-exciton nonreciprocal entanglement not only can be generated at room temperature and even higher temperature but also exhibits highly robustness to cavity dissipation. Our works open a way to manipulate the room-temperature nonreciprocal entanglement, which may be useful for developing nonreciprocal quantum technologies.
