Twin-field quantum key distribution over 830-km fibre

Nature Photonics, Published online: 17 January 2022; doi:10.1038/s41566-021-00928-2Twin-field (TF) quantum key distribution (QKD) over a secure distance of 833.8 km is demonstrated even in the finite-size regime. To this end, an optimized four-phase TF-QKD protocol and a high-speed low-noise TF-QKD system are developed.

Subradiant directional memory in cooperative scattering

Nature Photonics, Published online: 10 January 2022; doi:10.1038/s41566-021-00926-4A theoretical study of the time dependence of backscattering enhancements is presented, where strongly scattering media present a directional memory for time-varying signals even when the direct input signal has long decayed, providing opportunities for controlling the...
