Born's rule from measurements of classical signals by threshold detectors which are properly calibrated

摘要

The very old problem of the statistical content of quantum mechanics (QM) isstudied in a novel framework. The Born's rule (one of the basic postulates ofQM) is derived from theory of classical random signals. We present ameasurement scheme which transforms continuous signals into discrete clicks andreproduces the Born's rule. This is the sheme of threshold type detection.Calibration of detectors plays a crucial role.
