Abstract

Exciton optomechanics, a hybrid platform facilitating nonlinear interactions among excitons, phonons, and photons, offers unique opportunities to explore light-matter interactions and their intrinsic nonlinearities. In this study, we propose a scheme to generate genuine tripartite entanglement among three exciton modes within an exciton-optomechanical system comprising a semiconductor optomechanical microcavity with three integrated quantum wells. The exciton modes supported by these quantum wells simultaneously interact with an optical cavity mode via a beam-splitter-type interaction and couple to a mechanical vibration mode through a nonlinear deformation potential interaction. By employing experimentally feasible parameters and carefully chosen detunings, the three exciton modes achieve resonance with the Stokes and anti-Stokes sidebands scattered by mechanical motion, enabling genuine tripartite entanglement. Notably, this steady-state entanglement is robust against thermal baths, providing a promising approach for generating excitonic multipartite entanglement.

通过激子光学力学实现激子模式的真正三方纠缠

激子光机械学是一个促进激子、声子和光子之间非线性相互作用的混合平台，为探索光-物质相互作用及其内在非线性提供了独特的机会。在这项研究中，我们提出了一种在激子-光机械系统中产生三种激子模式之间真正三方纠缠的方案，该系统由一个带有三个集成量子阱的半导体光机械微腔组成。这些量子阱支持的激子模式同时通过分光型相互作用与光腔模式相互作用，并通过非线性形变势相互作用与机械振动模式耦合。通过采用实验可行的参数和精心选择的失谐，三种激子模式与机械运动散射的斯托克斯和反斯托克斯边带实现了共振，实现了真正的三方纠缠。值得注意的是，这种稳态纠缠不受热浴的影响，为产生激子多方纠缠提供了一种前景广阔的方法。
