Tunneling - Overview

Tunneling is the quantum mechanical phenomenon where a particle moves through a potential barrier that it classically could not surmount. A classic example of tunneling is the passage of a classical electron through the potential barrier formed by the edges of a square potential well. Quantum mechanically, tunneling can be understood using the Heisenberg uncertainty principle and the wave–particle duality of matter. Tunneling is commonly observed in atomic, molecular, and solid-state systems. Tunneling is of particular importance in the field of quantum computing, and is the mechanism responsible for the quantum tunnelling effect, a process by which a particle tunnels through a barrier that it classically would not be able to surmount.
