Direct Measurement of a Nonlocal Entangled Quantum State.
Wei-Wei Pan,Xiao-Ye Xu,Yaron Kedem,Qin-Qin Wang,Zhe Chen,Munsif Jan,Kai Sun,Jin-Shi Xu,Yong-Jian Han,Chuan-Feng Li,Guang-Can Guo +10 more
TL;DR: Here, for the first time, a method is proposed to directly measure a nonlocal wave function of a bipartite system, using modular values, and is experimentally implemented for a photon pair in a hyperentangled state.
Journal ArticleDOI
Hybrid-cascaded generation of tripartite telecom photons using an atomic ensemble and a nonlinear waveguide
TL;DR: In this paper, a spontaneous Raman scattering process in a hot atomic ensemble cascaded by a spontaneous parametric downconversion process in periodically poled nonlinear waveguide was used to generate photon triplets in the telecommunications band.
Journal ArticleDOI
Minimal Tradeoff and Ultimate Precision Limit of Multiparameter Quantum Magnetometry under the Parallel Scheme.
Zhibo Hou,Zhao Zhang,Guo-Yong Xiang,Chuan-Feng Li,Guang-Can Guo,Hongzhen Chen,Liqiang Liu,Haidong Yuan +7 more
TL;DR: This work provides an approach to characterize the minimal tradeoff among the precisions of multiple parameters that arise from the incompatibility of the optimal probe states, which leads to the identification of the ultimate precision limit for the estimation of all three components of a magnetic field under the parallel scheme.
Journal ArticleDOI
Quantum coherence and state conversion: theory and experiment
Kang-Da Wu,Thomas Theurer,Guo-Yong Xiang,Chuan-Feng Li,Guang-Can Guo,Martin B. Plenio,Alexander Streltsov +6 more
TL;DR: In this article, the authors considered the problem of assisted incoherent state conversion, where the process is enhanced by making use of correlations with a second party, and showed that the optimal state-conversion probabilities can be achieved in a linear optics setup.
