Nonreciprocal transition between two indirectly coupled energy levels
Xun-Wei Xu, Hai-Quan Shi, Ai-Xi Chen
We propose a theoretical scheme to realize nonreciprocal transition between two energy levels that can not coupled directly. Suppose they are coupled indirectly by two auxiliary le…

Generation of single entangled photon-phonon pairs via an atom-photon-phonon interaction
Xun-Wei Xu, Hai-Quan Shi, Jie-Qiao Liao +1
Quantum blockade and entanglement play important roles in quantum information and quantum communication as quantum blockade is an effective mechanism to generate single photons (ph…

Cross-correlation between photons and phonons in quadratically coupled optomechanical systems
Xun-Wei Xu, Hai-Quan Shi, Ai-Xi Chen +1
We study photon, phonon statistics and the cross-correlation between photons and phonons in a quadratically coupled optomechanical system. Photon blockade, phonon blockade and stro…
