Introduction to the concept
[edit]The section "Introduction to the concept" heads the entire article off in the wrong direction. The following statement is false:
- In quantum mechanics, a particle can, with a small probability, tunnel to the other side, thus crossing the barrier.
It is this kind of statement that makes quantum tunneling so puzzling and description of it borderline misinformation.
In quantum mechanics there is no particle on the inside of the barrier. It is not possible to measure a particle then send it through a barrier and find it on the other side. We randomly observe particles outside of system we believe to be meta-stable. The model that predicts this result has a barrier (to provide meta-stability) and probability of observations. That's it. The randomness is what is non-classical.
Someday I will get the energy to get refs and redo this section. Johnjbarton (talk) 01:05, 24 May 2024 (UTC)
