Investigating a Quantum Key Distribution Scheme with Independent Detection and Sideband Encoding
The authors propose and test a quantum key distribution scheme with independent detection using sideband encoding and a Sagnac interferometer. The scheme provides automatic compensation for phase fluctuations in optical channels and demonstrates stable interference of weak coherent states over a 25-km link with a low error rate, confirming it can be used to build secure quantum networks.
