Quantum-limited optical time transfer for future geosynchronous links

June 21, 2023
Author(s)
Emily Caldwell, Jean-Daniel Deschenes, Jennifer Ellis, William C. Swann, Benjamin Stuhl, Hugo Bergeron, Nathan R. Newbury, Laura Sinclair
The combination of optical time transfer and optical clocks opens up the possibility of large-scale free-space networks that connect both ground-based optical clocks and future space-based optical clocks. Such networks promise better tests of general

Photon Efficient Optical Time Transfer

Emily Caldwell, Laura Sinclair, William C. Swann, Nathan R. Newbury, Benjamin Stuhl, Jean-Daniel Deschenes
We present a novel frequency comb-based system for optical two-way time-frequency transfer to support very long distance free-space links between clocks. Our Photon-Efficient Agile Comb Optical Clock Synchronization (PEACOCS) system supports sub
