Testing macroscopic quantum coherence

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

Summary

The compatibiity of Macrorealism and Quantum Mechanics is discussed in the light of some recent experimental proposals based on non-invasive measurements realized via SQUID techniques that aim at evidentiating violation of a class of Bell-like inequalities. In particular, it is pointed out that the assumption of «non-invasivity» with respect to a measurement process is independent of any «macrorealistic» assumption about physical reality and that the conjunction of both assumptions ultimately amounts to a request of classical behaviour.
