Secure Key from Quantum Discord
Rong Wang, Guan-Jie Fan-Yuan, Zhen-Qiang Yin +6
The study of quantum information processing seeks to characterize the resources that enable quantum information processing to perform tasks that are unfeasible or inefficient for c…
Long-distance continuous-variable measurement-device-independent quantum key distribution with discrete modulation
Hong-Xin Ma, Peng Huang, Dong-Yun Bai +4
We propose a long-distance continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) protocol with discrete modulation. This kind of discrete-modulat…
Experimental Blind Quantum Computing for a Classical Client
He-Liang Huang, Qi Zhao, Xiongfeng Ma +8
To date, blind quantum computing demonstrations require clients to have weak quantum devices. Here we implement a proof-of-principle experiment for completely classical clients. Vi…
Ground state cooling in a hybrid optomechanical system with a three-level atomic ensemble
Tan Li, Shuo Zhang, He-Liang Huang +4
Cooling mechanical resonators is of great importance for both fundamental study and applied science. We investigate the hybrid optomechanical cooling with a three-level atomic ense…
Detection efficiency and noise in semi-device independent randomness extraction protocol
Hong-Wei Li, Zhen-Qiang Yin, Marcin Pawlowski +2
In this paper, we analyze several critical issues in semi-device independent quantum information processing protocol. In practical experimental realization randomness generation in…
Tight finite-key analysis for passive decoy-state quantum key distribution under general attacks
Chun Zhou, Wan-su Bao, Hong-wei Li +5
For quantum key distribution (QKD) using spontaneous parametric-down-conversion sources (SPDCSs), the passive decoy-state protocol has been proved to be efficiently close to the th…
