提出了一种在光电机械混合系统中实现光子和微波光子关联的方案，其中机械谐振器与光场和微波场耦合。分析和数值模拟结果表明，Stokes光子和反Stokes光子之间的互相关函数强烈地违反了Cauchy-Schwarz不等式，证实了可见光光子和微波光子之间的非经典关联.值得注意的是，可能用于量子通信的具有巨大不同波长的非经典光子对是在实验上可达到的弱耦合极限而不是单光子强耦合机制下产生的。此外，该协议提供了一种可能的途径，联合收割机的各自的优点，光学光子，微波光子，声子在混合电光机械系统。
A scheme to correlate optical and microwave photons is proposed in a hybrid electro-optomechanical system, where mechanical resonator is coupled to both optical and microwave fields. Analytical and numerical simulation results show that the cross-correlation function between Stokes and anti-Stokes photons strongly violates the Cauchy–Schwarz inequality, which confirms the nonclassical correlation between the optical and microwave photons. It is worth noting that the nonclassical photon pairs with vast different wavelengths, which may be useful for quantum communication, are generated under the experimentally accessible weak coupling limit rather than single-photon strong coupling regime. In addition, the protocol provides a possible route to combine the respective advantages of optical photons, microwave photons, and phonons in a hybrid electro-optomechanical system.
