By exploiting two mechanical modes in an optomechanical resonator, photon–phonon single pairs with both discrete- and continuous-variable entanglements can be generated in a waveguide that is coupled to the resonator. The discrete- and continuous-variable entanglements in the photon–phonon pair can be independently controlled via adjusting the central frequency and spectral width of the input optical pump, respectively.

光机械产生的光子-声子单对，具有离散和连续变量纠缠

通过利用光机械谐振器中的两种机械模式，可以在耦合到谐振器的波导中生成具有离散和连续变量纠缠的光子-声子单对。光子-声子对中的离散变量和连续变量纠缠可以分别通过调整输入光泵的中心频率和光谱宽度来独立控制。
