Quantum tunneling is one of the most intriguing phenomena in quantum mechanics. It describes a particle’s ability to pass through a potential barrier that, according to classical physics, should be impenetrable. Imagine a ball thrown against a wall: in the macroscopic world, it would stop upon impact. However, in the quantum realm, there’s a small probability that the ball “tunnels” through the wall and appears on the other side. … More Quantum Tunneling: A Gateway to the Subatomic World
