Journal ArticleDOI
Dynamical oscillator-cavity model for quantum memories
Qiongyi He,Margaret D. Reid,Margaret D. Reid,Elisabeth Giacobino,Jean Cviklinski,Peter D. Drummond +5 more
TL;DR: In this article, a dynamical approach to quantum memories using an oscillator-cavity model is proposed, which overcomes the known difficulties of achieving high quantum input-output fidelity with long storage times compared to the input signal duration.
Journal ArticleDOI
Deterministic Distribution of Multipartite Entanglement and Steering in a Quantum Network by Separable States.
Meihong Wang,Yu Xiang,Yu Xiang,Haijun Kang,Dongmei Han,Yang Liu,Qiongyi He,Qiongyi He,Qihuang Gong,Qihuang Gong,Xiaolong Su,Kunchi Peng +11 more
TL;DR: In this paper, the authors demonstrate the deterministic distribution of two-and three-mode Gaussian entanglement and steering by transmitting separable states in a network consisting of a quantum server and multiple users.
Journal ArticleDOI
Entanglement, number fluctuations and optimized interferometric phase measurement
Qiongyi He,Qiongyi He,Timothy G. Vaughan,Timothy G. Vaughan,Peter D. Drummond,Margaret D. Reid +5 more
TL;DR: In this paper, the authors derived a phase-entanglement criterion for two bosonic modes that is immune to number fluctuations, using the generalized Moore-Penrose inverse to normalize the phase-quadrature operator.
Journal ArticleDOI
Collective multipartite Einstein-Podolsky-Rosen steering: more secure optical networks.
TL;DR: The collective tripartite steering is formalized in terms of local hidden state model and the steering inequalities that act as signatures are given and how to optimize collective tri partite steering in specific optical schemes are suggested.
Journal ArticleDOI
Testing for Multipartite Quantum Nonlocality Using Functional Bell Inequalities
TL;DR: It is shown that arbitrary functions of continuous variables, e.g., position and momentum, can be used to generate tests that distinguish quantum theory from local hidden variable theories, and that optimized functional inequalities are resistant to standard forms of decoherence.
