Abstract
A central challenge to high-rate entanglement distribution is creating and maintaining precision synchronization of entanglement sources in different locations. This may be particularly challenging for long-distance satellite-based entanglement distribution for which photons should be synchronized to ~1 ps over roughly 400-2000 km distances between platforms with ~7 km/s relative motion. This present technology includes an entanglement distribution architecture and an associated distributed control technique employing quantum interference to generate a timing discriminant that is robust under lossy, fading atmospheric channels and suitable for use with today's quantum entanglement distribution technologies that can enable high rate, long distance satellite-based quantum networking.
