Purification of multipartite entanglement by local operations
Ming Yang, Fei Yan, Zhuo-Liang Cao
Multipartite entanglement purification is revisited by using the Local operations and classical communications(LOCCs). We demonstrate our idea by considering the tripartite case, i…
Effect of different Dzyaloshinskii-Moriya interactions on entanglement in the Heisenberg XYZ chain
Da-Chuang Li, Zhuo-Liang Cao
In this paper, we study the thermal entanglement in a two-qubit Heisenberg XYZ system with different Dzyaloshinskii-Moriya (DM) couplings. We show that different DM coupling parame…
Thermal entanglement in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-Moriya interaction
Da-Chuang Li, Xian-Ping Wang, Zhuo-Liang Cao
The thermal entanglement is investigated in a two-qubit Heisenberg XXZ system with Dzyaloshinskii-Moriya (DM) interaction. It is shown that the entanglement can be efficiently cont…
Discrete quantum Fourier transform in coupled semiconductor double quantum dot molecules
Ping Dong, Ming Yang, Zhuo-Liang Cao
In this Letter, we present a physical scheme for implementing the discrete quantum Fourier transform in a coupled semiconductor double quantum dot system. The main controlled-R gat…
Generation of cluster states with Josephson charge qubits
Xiao-Hu Zheng, Ping Dong, Zheng-Yuan Xue +1
A scheme for the generation of the cluster states based on the Josephson charge qubit is proposed. The two-qubit generating case is first introduced, and then generalized to multi-…
Scheme for preparation of W state via cavity QED
Zhuo-Liang Cao, Ming Yang
In this paper, we presented a physical scheme to generate the multi-cavity maximally entangled W state via cavity QED. All the operations needed in this scheme are to modulate the…
