Quantum enhanced phase estimation and locking of metropolitan-scale fiber link with faint light
We demonstrate quantum-enhanced phase estimation and locking over deployed metropolitan links up to 120 km using faint light. Our time-division multiplexed stabilization protocol enables coexistence of quantum and classical signals within shared channels.
