Key Points

Measured core-to-core time deviation is below 1×10-16, ensuring precise timing in quantum networks.
Cross-talk to a quantum channel is estimated to be less than 0.1 photons/second, enhancing stability and performance.
The method involves stabilization across 40 km of 7-core optical fiber, using separate cores for stabilization and quantum channels.
These findings support the development of more robust quantum communication systems in various applications.

Implication

Demonstration of link stabilization with quantum channels in separate optical fiber cores, indicating minimal cross-talk.

Abstract

We demonstrate link stabilization across 40 km of 7-core optical fiber, with stabilization and quantum channels in separate cores. Measured core-to-core time deviation is below 1×10 -16 and estimated cross-talk to a quantum channel <0.1 photons/second.
