The results of numerous Bell tests are viewed as evidence of quantum entanglement: the instant inner connection between totally separated entangled particles, which explains the ‘spooky action at a distance’, a term coiled by Einstein. The paper proposes a variation to Bell tests, aiming to prove or disprove spooky action from a distance. The main variation is an added pair of half-waveplates, with which we can change the relative polarization angle of the entangled photon pairs and assess its impact. The paper has derived the quantum prediction of Bell tests due to the changes in both the relative polarization angle of the entangled photon pairs and in the relative angle of the polarization measurement devices. If the quantum prediction is proven correct by experiments, the claim of instant inner connection between entangled particles or spooky action from a distance must be false.
