Multicore fiber harnesses correlated noise between cores to stabilize a quantum channel to 100 attoseconds jitter over 40 km at 100% duty cycle with only 0.01 spurious photons per second from Raman scattering.
Delivering the same optical frequency at two places: accurate cancellation of phase noise introduced by an optical fiber or other time -varying path,

Sub-femtosecond stabilization of multicore fiber for high-fidelity quantum networking at 100% duty cycle
Multicore fiber harnesses correlated noise between cores to stabilize a quantum channel to 100 attoseconds jitter over 40 km at 100% duty cycle with only 0.01 spurious photons per second from Raman scattering.
