Device-independent quantum key distribution over 100 km with single atoms
Bo-Wei Lu, Chao-Wei Yang, Run-Qi Wang +15
Device-independent quantum key distribution (DI-QKD) is a key application of the quantum internet. We report the realization of DI-QKD between two single-atom nodes linked by 100-k…

Compact and fully functional high-frequency sine wave gating InGaAs/InP single-photon detector module
Qi Xu, Chao Yu, Dajian Cui +7
High-frequency sine wave gating (SWG) InGaAs/InP single-photon detectors (SPDs) are widely used for synchronous near-infrared single-photon detection. For practical use, the size o…
