Hi,

In Decoherence all is quantum, is there a Counterfactual Definiteness in Decoherence?
 
Physics news on Phys.org
No. Decoherence says that when a quantum object interacts with a measuring device, the system will very quickly evolve into a state corresponding to one of the possible results. This isn't going to tell us anything about some other measurement that we haven't made so there's no measuring device with which to interact.
