Query: Revisiting the experimental test of Mermin's inequalities at IBMQ   Bell-type inequalities allow for experimental testing of local hidden
variable theories. In the present work we show the violation of Mermin's
inequalities in IBM's five-qubit quantum computers, ruling out the local
realism hypothesis in quantum mechanics. Furthermore, our numerical results
show significant improvement with respect to previous implementations. The
circuit implementation of these inequalities is also proposed as a way of
assessing the reliability of different quantum computers.
