Witnessing entanglement via the geometric phase in a impurity-doped Bose-Einstein condensate
X. Wu, S. P. Jia, C. L. Cai +1
We propose a theoretical scheme to witness quantum entanglement via the geometric phase in an impurity-doped Bose-Einstein condensate (BEC), which is a micro-macro quantum system c…

Reversible optical-microwave quantum conversion assisted by optomechanical dynamically-dark modes
Ling-Ying Zhu, Yong Dong, Ji Zhang +2
We propose a dynamically-dark-mode (DDM) scheme to realize the reversible quantum conversion between microwave and optical photons in an electro-optomechanical (EOM) model. It is s…

Mechanical engineering of photon blockades in a cavity optomechanical system
Cuilu Zhai, Ran Huang, Baijun Li +2
We propose to mechanically control photon blockades (PB) in an optomechanical system with driving oscillators. We show that by tuning the mechanical driving parameters we achieve s…
