The applications of the general and reduced Yangian algebras
Li-Guo Qin, Li-Jun Tian, Yan-Ling Jin +1
The applications of the general and reduced Yangian Y(sl(2)) and Y(su(3)) algebras are discussed. By taking a special constraint, the representation of Y(sl(2)) and Y(su(3)) can be…
Dynamics of quantum correlations for two-qubit coupled to a spin chain with Dzyaloshinskii-Moriya interaction
Yi-ying Yan, Li-jun Tian, Li-guo Qin
We study the dynamics of quantum discord and entanglement for two spin qubits coupled to a spin chain with Dzyaloshinsky-Moriya (DM) interaction. We numerically and analytically in…
Quantum correlation in three-qubit Heisenberg model with Dzyaloshinskii-Moriya interaction
Li jun Tian, Yi ying Yan, Li guo Qin
We investigate the pairwise thermal quantum discord in a three-qubit XXZ model with Dzyaloshinskii-Moriya (DM) interaction. We find that the DM interaction can increase quantum dis…
Quantum entanglement and teleportation in quantum dot
Li-Guo Qin, Li-Jun Tian, Guo-Hong Yang
We study the thermal entanglement and quantum teleportation using quantum dot as a resource. We first consider entanglement of the resource, and then focus on the effects of differ…
The sudden birth and sudden death of thermal fidelity in a two-qubit XY model
Li-Jun Tian, Li-Guo Qin, Ying Jiang +1
We study the energy level crossings of the states and thermal fidelity for a two-qubit system in the presence of a transverse and inhomogeneous magnetic field. It is shown clearly…
