Method of relativistic syntonization of quantum clocks: experimental studies

Abstract

A method of relativistic syntonization is proposed and experimentally investigated, which is designed to transfer the exact value of the frequency to remote quantum clocks, taking into account relativistic effects caused by the potential difference of the gravitational fi eld and the 2nd order Doppler effect. The implementation of the method is based on the use of relocated highly stable hydrogen quantum clocks. The purpose of the experimental study was to assess the accuracy of transmitting the frequency value from the time units, frequency and the national time scale State primary standard GET 1-2022 to a remote consumer located in Evpatoria. The experiment takes into account the initial discrepancy between the frequencies of the master oscillators of stationary and relocated quantum clocks and their temperature shifts along the way. The relative error of syntonization, taking into account all interfering factors, was 4,6∙10–16, which is 37 times less than as a result of code measurements from the signals of global navigation satellite systems, and 25 times less than when using satellite duplex comparisons. The investigated method is proposed for applying in the creation of measuring networks of highly stable quantum clocks.
