Improved lower and upper bounds for entanglement of formation
Xue-Na Zhu, Shao-Ming Fei
We provide analytical lower and upper bounds for entanglement of formation for bipartite systems, which give a direct relation between the bounds of entanglement of formation and c…
Lower Bound of Multipartite Concurrence Based on Sub-quantum State Decomposition
Xue-Na Zhu, Ming-Jing Zhao, Shao-Ming Fei
We study the entanglement of tripartite quantum states and provide analytical lower bound of concurrence in terms of the concurrence of sub-states. The lower bound may improve all…
Lower Bound of Concurrence Based on Positive Maps
Xiao-Sheng Li, Xiu-Hong Gao, Shao-Ming Fei
We study the concurrence of arbitrary dimensional bipartite quantum systems. An explicit analytical lower bound of concurrence is obtained, which detects entanglement for some quan…
Coherent bimolecular reactions with quantum-degenerate matter waves
H. Jing, J. Cheng, P. Meystre
We demonstrate theoretically that the abstraction reaction can be driven coherently and efficiently with quantum-degenerate bosonic or fermionic matter waves. We s…
Quantum Noise in the Collective Abstraction Reaction A+B AB+B
H. Jing, J. Cheng, P. Meystre
We demonstrate theoretically that the collective abstraction reaction A+B AB+B can be realized efficiently with degenerate bosonic or fermionic matter waves. We show that t…
Coherent atom-trimer conversion in a repulsive Bose-Einstein condensate
H. Jing, J. Cheng, P. Meystre
We show that the use of a generalized atom-molecule dark state permits the enhanced coherent creation of triatomic molecules in a repulsive atomic Bose-Einstein condensate, with fu…
