Berry phase and entanglement of 3 qubits in a new Yang-Baxter system
Taotao Hu, Chunfeng Wu, Kang Xue
In this paper we construct a new matrix from the matrix, where / is the image of the braid group representation. The $ 8\tim…
Effective Hamiltonian Approach to Open Systems and Its Applications
X. L. Huang, X. X. Yi, Chunfeng Wu +3
By using the effective Hamiltonian approach, we present a self-consistent framework for the analysis of geometric phases and dynamically stable decoherence-free subspaces in open s…
A scheme for unconventional geometric quantum computation in cavity QED
Xun-Li Feng, Zisheng Wang, Chunfeng Wu +2
We present a scheme for implementing the unconventional geometric two-qubit phase gate with nonzero dynamical phase by using the two-channel Raman interaction of two atoms in a cav…
Quantum Nonlocality of N-qubit W states
Chunfeng Wu, Jing-Ling Chen, L. C. Kwek +1
An experimental setup for testing quantum nonlocality of N qubits is proposed. This method is a generalization of the optical setup proposed by Banaszek and Wodkiewicz [1]. The qua…
Violating Bell Inequalities Maximally for Two -Dimensional Systems
Jing-Ling Chen, Chunfeng Wu, L. C. Kwek +2
We investigate the maximal violation of Bell inequalities for two -dimensional systems by using the method of Bell operator. The maximal violation corresponds to the maximal eig…
Gisin's Theorem for Three Qubits
Jing-Ling Chen, Chunfeng Wu, L. C. Kwek +1
We present a Theorem that all generalized Greenberger-Horne-Zeilinger states of a three-qubit system violate a Bell inequality in terms of probabilities. All pure entangled states…
