我们提出了如何通过控制光学暗模（ODM）来产生三方光振动纠缠，光学暗模是由两个光学模耦合到一个共同的振动模引起的。该ODM与振动解耦，并且可以通过采用合成规范场来根据需要进行控制，这可以实现ODM未中断和ODM中断状态之间的有效切换。我们发现，三方光机械纠缠在很大程度上抑制了在ODM-unbreaking制度，但它是显着增强的ODM-breaking制度。特别地，在ODM-breaking机制下量子纠缠的噪声鲁棒性可以是在ODM-unbreaking机制下的两倍以上。该研究为保护和增强脆弱的量子资源，构建抗噪声和抗暗模的量子处理器和纠缠网络提供了一种方法。
We propose how to generate a tripartite light-vibration entanglement by controlling an optical dark mode (ODM), which is induced by the coupling of two optical modes to a common vibrational mode. This ODM is decoupled from the vibration, and it can be controlled on demand by employing a synthetic gauge field, which can enable efficient switching between the ODM-unbreaking and ODM-breaking regimes. We find that the tripartite optomechanical entanglement is largely suppressed in the ODM-unbreaking regime, but it is significantly enhanced in the ODM-breaking regime. In particular, the noise robustness of quantum entanglement in the ODM-breaking regime can be more than twice than that in the ODM-unbreaking regime. This study offers a method for protecting and enhancing fragile quantum resources and for constructing noise-tolerant and dark-mode-immune quantum processors and entangled networks.
