Phononic entanglement concentration via optomechanical interactions
Shan-Shan Chen, Hao Zhang, Qing Ai +1
Low dissipation, tunable coupling to other quantum systems, and unique features of phonons in the aspects of propagation, detection and others suggest the applications of quantized…
Fast and robust quantum control for multimode interactions by using shortcuts to adiabaticity
Hao Zhang, Xue-Ke Song, Qing Ai +3
Adiabatic quantum control is a very important approach for quantum physics and quantum information processing. It holds the advantage with robustness to experimental imperfections…
Universal single-qubit non-adiabatic holonomic quantum gates in optomechanical system
Shan-Shan Chen, Hao Zhang, Xue-Ke Song +5
The non-adiabatic holonomic quantum computation with the advantages of fast and robustness attracts widespread attention in recent years. Here, we propose the first scheme for real…
Stability and phase transition of localized modes in Bose-Einstein condensates with both two- and three-body interactions
Xiao-Dong Bai, Qing Ai, Mei Zhang +3
We investigate the stability and phase transition of localized modes in Bose-Einstein Condensates (BECs) in an optical lattice with the discrete nonlinear Schrödinger model by cons…
