Hidden variables in Mermin GHZ machine with quantum assistance
Three experiments, with an IBM superconducting quantum computer, are
presented, where the setting combinations on a three qubit GHZ(like) state were
selected by two additional assistant qubits. The average of the polynomial of
Mermin for the three entangled qubits was calculated; the results showed
violation of the inequality of Mermin. However, given that the assistant qubits
selected, imposed and informed the type of settings, it was possible to
interpret the results in terms of arranged relations among hidden variables of
the assistants and the entanglement BEFORE each shot; the hidden variables may
or may not be local depending on the way the qubits were initialized.
