Quantum tunneling is faster than light travel ? My reasoning is that the particle cannot be detected inside the tunnel so if it travels from A to B it must be instantly going from A to B , hence faster than light travel ?
This seems legit for the particle interpretation. And also for waves imho. Some people mention the uncertainty principle but I do not see how that explains it.
Answer
Faster-than-light tunneling appears only in non-relativistic quantum mechanics. As soon as you introduce the concept of relativity to QM, faster-than-light tunneling disappears.
