Quantum nonlocality of N-qubit W states
Quantum nonlocality of N-qubit W states
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 W\'odkiewicz [Phys. Rev. Lett. 82, 2009 (1999)]. The quantum nonlocality of $N$ qubits can be obtained through its violation of $N$-qubit Bell inequalities. The correlation …
