Bell inequalities for continuous-variable measurements
TL;DR: In this article, a comparison of local hidden-variable theories using measurements with continuous-variable (CV) outcomes is presented, and the results show that the moment-based Cavalcanti-Foster-Reid-Drummond inequalities with an optimal function have greater robustness to both loss and noise.
Journal ArticleDOI
Phase control of entanglement and quantum steering in a three-mode optomechanical system
Feng-Xiao Sun,Feng-Xiao Sun,D. Mao,Y. T. Dai,Zbigniew Ficek,Zbigniew Ficek,Qiongyi He,Qiongyi He,Qihuang Gong,Qihuang Gong +9 more
TL;DR: In this article, the phase control of coherence, entanglement and quantum steering in an optomechanical system composed of a single mode cavity containing a partially transmitting dielectric membrane and driven by short laser pulses is investigated.
Journal ArticleDOI
Role of thermal noise in tripartite quantum steering
TL;DR: In this paper, the influence of thermal noise on bipartite and tripartite quantum steering induced by a short laser pulse in a hybrid three-mode optomechanical system is investigated.
Journal ArticleDOI
Dynamics of transient cat states in degenerate parametric oscillation with and without nonlinear Kerr interactions
R. Y. Teh,Feng-Xiao Sun,Feng-Xiao Sun,R. E. S. Polkinghorne,Qiongyi He,Qihuang Gong,Peter D. Drummond,Peter D. Drummond,Margaret D. Reid,Margaret D. Reid +9 more
TL;DR: In this article, the authors studied the dynamics of the creation and decoherence of cat states in degenerate parametric oscillation, both with and without the Kerr nonlinearity found in recent superconducting-circuit experiments that generate cat states.
Journal ArticleDOI
Dynamical preparation of Einstein-Podolsky-Rosen entanglement in two-well Bose-Einstein condensates
TL;DR: In this paper, a dynamical process similar to that employed in quantum optics is proposed to generate entanglement between groups of atoms in a two-well Bose-Einstein condensate.
