Synchronization Networks for Quantum DC

"Ya-Shian Li-Baboud (Computer Scientist) - Nist Precision time synchronization between quantum nodes is required to support quantum state distribution at practical rates and distances. This study explores an interoperable optical two-way time transfer method using existing telecommunications infrastructure to support rapid deployment of time synchronization capabilities in quantum research networks. An additional capability beneficial to quantum networks is co-existence among classical clock transfer with single-photon level entangled quantum state distribution. Co-existing clock signals enables in-situ path delay estimation for active phase delay compensation in order to achieve quantum interference between remote sources at higher rates.This study characterizes the clock synchronization precision achieved between different topologies and includes measurements of temperature effect on wavelength dispersion and polarization stability based on optical power for a fiber link pair comprised of both aerial and buried segments."
