Abstract

Standard EPR-type experiments, both of the Bohm-Bell and the GHZ kind, are operationally signified by the property that each of the correlated particles can be detected in either one of the two output ports of the measuring device. These may be the two channels of a polarizer^[1] or the two output beams of an interferometer.^[2] Consequently, formulations of Bell’s inequalities and of the GHZ theorem employ two-valued, i.e. dichotomic, output variables.
