We propose a realistic protocol for the preparation and readout of mechanical Bell states in an optomechanical system. The proposal relies on parameters characterizing a photonic crystal cavity mode, coupled to two localized flexural modes of the structure, but equally applies to other optomechanical systems in the same parameter range. The nonclassical states are heralded via optical postselection and revealed in specific interference patterns characterizing the emission at the cavity frequency.
我们提出了一种用于在光机械系统中制备和读出机械贝尔态的现实协议。该协议依赖于表征光子晶体腔模的参数，该腔模与结构的两个局域弯曲模耦合，但同样适用于相同参数范围内的其他光机械系统。通过光学后选择来预示非经典态，并在表征腔频率发射的特定干涉图样中揭示这些态。
