Device-independent quantum key distribution with random postselection
Feihu Xu, Yu-Zhe Zhang, Qiang Zhang +1
Device-independent quantum key distribution (QKD) can permit the superior security even with unknown devices. In practice, however, the realization of device-independent QKD is tec…
Photonic verification of device-independent quantum key distribution against collective attacks
Wen-Zhao Liu, Yu-Zhe Zhang, Yi-Zheng Zhen +6
In this paper, we employ theoretical and experimental efforts and realize a proof-of-principle verification of device-independent QKD based on the photonic setup. On the theoretica…
Non-line-of-sight imaging with picosecond temporal resolution
Bin Wang, Ming-Yang Zheng, Jin-Jian Han +5
Non-line-of-sight (NLOS) imaging enables monitoring around corners and is promising for diverse applications. The resolution of transient NLOS imaging is limited to a centimeter sc…
Measurement-Device-Independent Verification of a Quantum Memory
Yong Yu, Peng-Fei Sun, Yu-Zhe Zhang +9
In this paper we report an experiment that verifies an atomic-ensemble quantum memory via a measurement-device-independent scheme. A single photon generated via Rydberg blockade in…
Single-photon imaging over 200 km
Zheng-Ping Li, Jun-Tian Ye, Xin Huang +9
Long-range active imaging has widespread applications in remote sensing and target recognition. Single-photon light detection and ranging (lidar) has been shown to have high sensit…
Distributed quantum phase estimation with entangled photons
Li-Zheng Liu, Yu-Zhe Zhang, Zheng-Da Li +8
Distributed quantum metrology can enhance the sensitivity for sensing spatially distributed parameters beyond the classical limits. Here we demonstrate distributed quantum phase es…
