Anomalous weak values via a single photon detection.

Is it possible that a measurement of a spin component of a spin-1/2 particle yields the value 100? In 1988 Aharonov, Albert and Vaidman argued that upon pre- and postselection of particular spin states, weakening the coupling of a standard measurement procedure ensures this paradoxical result. This theoretical prediction, called weak value, was realised in numerous experiments, but its meaning remains very controversial, since its "anomalous" nature, i.e.
