Patent number: 10187205Abstract: System and methods for synchronizing and aligning quantum channel for Quantum Key Distribution. The primary object of the invention is to allow a Quantum Key Distribution (QKD) apparatus to work continuously with only two communication channels, a quantum communication channel and a service channel. This is achieved by linking the clock frequencies of both channels and completed by an over-sampling method for phase synchronization tracking. Clock signal carry is done through data using a clock data recovery encoding techniques. Having a continuous operating QKD system is not possible without a tracking system that enables phase alignment. This synchronization and alignment system and method for QKD has multiple benefits as it allows real-time synchronization with continuous data flow and is not dedicated to a specific quantum protocol.Type: GrantFiled: October 28, 2015Date of Patent: January 22, 2019Assignee: Université de GenèveInventors: Olivier Guinnard, Raphael Houlman
