Genuine multipartite entanglement detection and lower bound of multipartite concurrence
Ming Li, Shao-Ming Fei, Xianqing Li-Jost +1
The problems of genuine multipartite entanglement detection and classification are challenging. We show that a multipartite quantum state is genuine multipartite entangled if the m…
Evolution equation for quantum coherence
Ming-Liang Hu, Heng Fan
The estimation of the decoherence process of an open quantum system is of both theoretical significance and experimental appealing. Practically, the decoherence can be easily estim…

Stimulated Raman adiabatic passage (STIRAP) offers significant advantages for coherent population transfer between un- or weakly-coupled states and has the potential of realizing e…
Optimizing Quantum Adiabatic Algorithm
Hongye Hu, Biao Wu
In quantum adiabatic algorithm, as the adiabatic parameter changes slowly from zero to one with finite rate, a transition to excited states inevitably occurs and this induce…
Efficient Scheme for Perfect Collective Einstein-Podolsky-Rosen Steering
M. Wang, Q. H. Gong, Z. Ficek +1
A practical scheme for the demonstration of perfect one-sided device-independent quantum secret sharing is proposed. The scheme involves a three-mode optomechanical system in which…
Self-Sustained Oscillation and Dynamical Multistability of Optomechanical Systems in the Extremely-Large-Amplitude Regime
Ming Gao, Fuchuan Lei, Chuanguang Du +1
Optomechanics concerns with the coupling between optical cavities and mechanical resonators. Most early works are concentrated in the physics of optomechanics in the small-displace…
