论文摘要
我们研究了通过混合光电机械系统中的机械谐振器，超导乘以与外部光场的同步。量子轨迹方法用于研究同步。对于单个量子轨迹运行，观察到量子旋转旋转的量子旋转量的量子偏振矢量之一中的双重性。稳定状态之一的旋转与外部光学驱动器同步。当轨迹的数量显着增加时，量子量将不再显示双重性。但是，仍然观察到与量子波动较少的同步。该方案可用于通过同步将微波量子旋转的旋转相传递到长寿命的光光子，这可能会在长距离量子通信中找到应用。同样，该混合系统可用于研究量子同步。
We study the synchronization of a superconducting qubit to an external optical field via a mechanical resonator in a hybrid optoelectromechanical system. The quantum trajectory method is employed to investigate synchronization. The bistability in one of the qubit polarization vectors, where the qubit rotates about the polarization vector, is observed for a single quantum trajectory run. The rotation in one of the stable states is synced with the external optical drive. When the number of trajectories is significantly increased, the qubit no longer displays bistability. However, synchronization with less quantum fluctuations is still observed. The scheme could be used to transfer the phase of the microwave qubit's rotation to a long-lived optical photon through synchronization, which may find applications in long-distance quantum communication. Also, this hybrid system can be used to study quantum synchronization.
