Experimentally simulating the violation of Bell-type inequalities for generalized GHZ states

Using NMR techniques, we implemented the simulation of the violations of two Bell-type inequalities: Mermin-Ardehali-Belinskii-Klyshko (MABK) inequality and Chen's inequality, for the 3-qubit generalized GHZ states. The experimental results are in good agreement with the quantum predictions and show that Chen's inequality is more efficient than MABK inequality in the case of the generalized GHZ entangled states.
