Some simple remarks about quantum nonseparability for systems composed of identical constituents

Некоторые простые замечания о квантовой неразделимости для систем, образованных из тождественных подсистем

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

Summary

It is shown that, for a system composed of two identical subsystems, the only states for which definite physical properties can be attributed to the constituents are those obtained by symmetrizing or antisymmetrizing a factorized state.

Riassunto

Si mostra che, per un sistema composto di due sottosistemi identici, i soli stati per i quali è possibile attribuire proprietà fisiche definite ai costituenti sono quelli ottenuti tramite la simmetrizzazione o l'antisimmetrizzazione di uno stato fattorizzato.

Резюме

Показывается, что для системы, образованной двумя тождественными подсистемами, единственными состояниями, для которых определенные физические свойства могут быть приписаны составляющим частям, являются такие состояния, которые получаются посредством симметризации или антисимметризации факторизованного состояния.
