Journal ArticleDOI
Preparation of multi-photon states without optical interferometers
TL;DR: In this article, a linear optical experimental scheme was proposed to generate multi-photon states through degenerate collinear parametric down conversion process, which does not need optical interferometers and provides a convenient and reliable photon source in future quantum information science researches.
Journal ArticleDOI
Finite-key analysis for twin-field quantum key distribution based on generalized operator dominance condition
Rui-Qiang Wang,Zhen-Qiang Yin,Feng-Yu Lu,Rong Wang,Shuang Wang,Wei Chen,Wei Huang,Bing-Jie Xu,Guang-Can Guo,Zheng-Fu Han +9 more
TL;DR: An improved finite-key analysis of twin-field QKD is proposed through devising new operator dominance condition and it is shown that by adding the number of decoy states, the secret key rate can be furtherly improved and approach the asymptotic bound.
Journal ArticleDOI
Transcoder for the spatial and temporal modes of a photon.
TL;DR: The realization of a photonic transcoder is reported, by which light with an arbitrary OAM superposition is experimentally converted into a time-bin Gaussian pulse, and vice versa, which paves the way towards a mixed optical communication in free-space and optical fibre.

Temporal Wheeler's delayed-Choice Experiment based on Cold Atomic Quantum Memory
Ming-Xin Dong,Dong-Sheng Ding,Yi-Chen Yu,Ying-Hao Ye,Wei-Hang Zhang,En-Ze Li,Lei Zeng,Kan Zhang,Li Dachuang,Guang-Can Guo,Bao-Sen Shi +10 more
TL;DR: In this paper, the authors demonstrate a delayed choice experiment in an interface of light and atomic memory, in which the cold atomic memory makes the heralded single photon divided into a superposition of atomic collective excitation and leaked pulse, thus acting as memory beam splitters.

TL;DR: In this article, the optical manipulation of charge state and coherent control of multifold divacancy spins ensemble in silicon carbide (SiC) under resonant excitation was studied. And the results reveal that the resonantly excited divacance ensemble counts have dozens of enhancements by repumping a higher-energy laser.
