Quantum Tunneling: Faster than Light
The eighth unique feature of the quantum world is that a particle can tunnel spontaneously from one place to another, bypassing the limit of the speed of light. How far the particle goes after this tunneling effect is limited only by probabilities the farther, the less probable. It has important applications to modern devices such as the tunnel diode, quantum computing, and the scanning tunneling microscope. Particles have the ability to cross barriers they shouldn’t be able to and the reason for this is the particle’s wave function.
