摘要
罗兰C系统受到原子钟工艺和无线电信号测量精度限制,难以实现台站间高精度时间同步。基于量子纠缠微波信号和腔电光力系统,通过将微波量子信号转换到光频域进行符合探测,可以得到更精准的罗兰C主副台的同步时差信息。经过理论分析和仿真,得出腔中微波和光转换的条件,以及腔内耗散对保真度的影响。通过控制腔的驱动场参数可实现最优相位灵敏度检测,精度水平能达到皮秒量级。相较于原有同步方式,无需使用昂贵原子时钟,无需测量脉冲到达时间,即能有效提高时间同步精度。
Abstract
Being limited by the accuracy of the atomic clock process and radio signal measurement, it’s difficult to achieve high-precision time synchronization between Roland C stations. Based on the quantum entangled microwave signal and cavity electro-opto-mechanical system, the more accurate synchronized time difference information of Roland C main and auxiliary stations can be obtained by converting the microwave quantum signal into the optical frequency domain for coincidence detection. Through theoretical analysis and simulation, the conditions of microwave and optical conversion in the cavity, as well as the effect of cavity dissipation on the fidelity are obtained. The optimal phase sensitivity detection can be realized by controlling the driving field parameters of the cavity, and the precision level can reach the picosecond level. Compared with the original synchronization method, this scheme can effectively improve the time measurement accuracy, without using expensive atomic clock and measuring the pulse arrival time.
