# Bell inequality and the locality loophole: Active versus passive switches

@article{Gisin1999BellIA, title={Bell inequality and the locality loophole: Active versus passive switches}, author={Nicolas Gisin and Hugo Zbinden}, journal={Physics Letters A}, year={1999}, volume={264}, pages={103-107} }

Abstract All experimental tests of the violation of Bell's inequality suffer from some loopholes. We show that the locality loophole is not independent of the detection loophole: in experiments using low efficient detectors, the locality loophole can be closed equivalently using active or passive switches.
