In quantum tunneling, when two states have a certain energy barrier, a wave effect can be created in such a way that the barrier can be breached from one state to another less energetic state through the interaction of third quantum state. This other player acts as an intermediary of exchange. One way to do this is to phase interfere a particle which kicks it from one state to the other through a constructive interference. It never actually exists in the place where the energy barrier (or exclusion zone) exists so it literally "tunnels" from one state to the other. Catalysts work this way. You can react H2 on a Pt-Pd plated ceramic sphere without ever getting to the ignition temperature of H2 (like at room temperature). Of course you get the right amount of heat out, just a lot less heat to start it. In this case it is lowering the barrier through the interaction of H2 with the metals on the surface.

Here is a link to a tunnel diode (where I learned about this effect first). It exhibits "negative resistance" behavior at a certain bias. Very cool. You increase the current and the voltage drop decreases.
