Free-Space Phase-Matching Quantum Key Distribution

2021 · 2021 13th International Conference on Wireless Communications and Signal Processing (WCSP)

As a practical version of twin-field quantum key distribution (TF-QKD), phase-matching quantum key distribution (PM-QKD) is able to surpass the linear bound without quantum repeaters. Implementing PM-QKD through free space can guarantee two parties to …

Phase-matching quantum key distribution with light source monitoring

2021 · Chinese Physics B

The transmission loss of photons during quantum key distribution (QKD) process leads to the linear key rate bound for practical QKD systems without quantum repeaters. Phase matching quantum key distribution (PM-QKD) protocol, an novel QKD …
