Abstract
A clock synchronization method is disclosed. The method comprises receiving master timing synchronization data from a master clock device, wherein the master timing synchronization data is based at least in part on quantum data obtained from a first quantum device of the master clock device. The method comprises determining local timing synchronization data that is based at least in part on local quantum data obtained from a second local quantum device, wherein the second local quantum device is entangled with the first quantum device such that the local quantum data and the quantum data obtained from the first quantum device are identical at a same time. The method comprises using the determined local timing synchronization data and the received master timing synchronization data to determine a timing correction factor. The method comprises correcting a local system time using the timing correction factor.
