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…

Continuous Multipartite Entangled State in Wigner Representation and the Violation of Zukowski-Brukner Inequality
Chunfeng Wu, Jing-Ling Chen, L. C. Kwek +2
We construct an explicit Wigner function for N-mode squeezed state. Based on a previous observation that the Wigner function describes correlations in the joint measurement of the…
