Abstract
Temporal Bell-like inequalities are derived taking into account the influence of the measurement apparatus on the observed magnetic flux in an rf-SQUID. Quantum measurement theory is shown to predict violations of these inequalities only when the flux states corresponding to opposite current senses are not distinguishable. Thus rf-SQUIDs cannot help to discriminate realism and quantum mechanics at the macroscopic level.File in questo prodotto:
