Cascaded Microwave Frequency Transfer over 300-km Fiber Link with Instability at the 10<sup>−18</sup> Level
Comparing and synchronizing atomic clocks between distant laboratories with ultra-stable frequency transfer are essential procedures in many fields of fundamental and applied science. Existing conventional methods for frequency transfer based on satellite links, however, are insufficient for the req...
