Some remarks on weak measurements and weak values
After a brief review of how weak measurements plus post- selection give rise to the weak value concept, I concentrate on its application to the so called Leggett-Garg inequalities, speculating also on what relevance these results may have to the basic assumptions behind the Bell inequality. I then criticize an interpretation of a weak value as any sort of bona fide property of the system under investi- gation. I even question whether the system can at all be said to “carry” its weak value.
