Thermal entanglement of Bosonic atoms in an optical lattice with nonlinear couplings
L. Zhou, X. X. Yi, H. S. Song +1
The thermal entanglement of two spin-1 atoms with nonlinear couplings in optical lattices is investigated in this paper. It is found that the nonlinear couplings favor the thermal…
Dynamics of Distillability
W. Wu, W. Wang, X. X. Yi
The time evolution of a maximally entangled bipartite systems is presented in this paper. The distillability criterion is given in terms of Kraus operators. Using the criterion, we…
Quantum logic gates and maximally entangled states in microtraps
X. X. Yi
This paper has been withdrawn because the first author submitted the paper without previously consulting the rest of the authors.
Dynamics of optically driven exciton and quantum decoherence
G. R. Jin, Yu-xi Liu, D. L. Zhou +2
By using the normal ordering method, we study the state evolution of an optically driven excitons in a quantum well immersed in a leaky cavity, which was introduced by Yu-xi Liu et…
On mass-dependent subtraction and removal of the ambiguity in QED renormalization
Jun-Chen Su, Xue-Xi Yi, Ying-Hui Cao
The QED renormalization is restudied by using a mass-dependent subtraction which is performed at a time-like renormalization point. The subtraction exactly respects necessary physi…
