Are Bell’s type inequalities sufficient conditions for local hidden-variable theories?

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

It is shown that however three unit vectorsi, j, kR 3 and three numbersR ij, Rik, Rjk are given satisfying the condition 0≤R ij,R ik,R jk≤1/2 and the Bell's type inequalities |1/2−R ij−Rik|≤Rjk≤1/2−|Rij−Rik|, three functionsf 1i, f1j, f1k exist which are a model of postulates of hidden-variable theories considered in a previous paper. Implications of this result are discussed, both from a mathematical and a physical point of view.

Riassunto

Si dimostra che, comunque dati tre vettori unitarii, j, kR 3 e tre numeriR ij, Rik, Rjk, soddisfacenti alla condizione 0≤R ij, Rik, Rjk≤1/2 e alle diseguaglianze del tipo di Bell |1/2−R ij−Rik|≤Rjk≤1/2−|Rij−Rik|, esistono tre funzionif 1i, f1j, f1k, che sono un modello dei postulati della teoria a variabili nascoste considerata in un precedente lavoro. Si discutono le implicazioni di tali risultati da un punto di vista sia matematico che fisico.
