Right. Decoherence is really uncontrolled and "in practice irreversible" entanglement, but in practice != in principle. The state is still in a superposition; it has just become practically impossible to demonstrate the fact.
- Filligree 9y agoThat just describes MWI, though. You can recover normality from it, so I don't see the unending superposition as being a problem.
- kgwgk 9y agoHow can you recover “normality” from it?
- AstralStorm 9y agoHow do you tell you have reached "normality" or whatever state you wished without perturbing the quantum system? (Yes there are some tricks like observing phase angle while changing velocity etc. Used in quantum cryptology.)
