Li-Zheng Liu,Yu-Zhe Zhang,Zheng-Da Li,Rui Zhang,Xu-Fei Yin,Yue-Yang Fei,Li Li,Nai-Le Liu,Feihu Xu,Yu-Ao Chen,Jian-Wei Pan +10 more
TL;DR: In this paper, the authors demonstrate distributed quantum phase estimation with discrete variables to achieve Heisenberg limit phase measurements, based on parallel entanglement in modes and particles, with an error reduction up to 1.4 dB and 2.7 dB below the shot-noise limit.

Wen-Zhao Liu,Yu-Zhe Zhang,Yi-Zheng Zhen,Ming-Han Li,Yang Liu,Jingyun Fan,Feihu Xu,Xiang Zhang,Jian-Wei Pan +8 more
TL;DR: In this article, the authors reported a proof-of-principle experiment of device-independent quantum key distribution (QKD) based on a photonic setup in the asymptotic limit and showed that the measured quantum correlations are strong enough to ensure a positive key rate under the fiber length up to 220m.

Device-independent quantum key distribution with random post selection.
TL;DR: In this paper, the authors proposed a device-independent QKD protocol with random post selection, where the secret keys are extracted only from the post-selected subset of outcomes.
