Quantum Tunneling

Definition

Quantum tunneling refers to when particles move through a barrier that they theoretically shouldn't be able to pass according to classical physics, due solely to quantum mechanical phenomena.

Analogy

Imagine you're playing a video game and there's a wall you can't get past. But due to a glitch (quantum mechanics), your character suddenly appears on the other side of the wall. That's quantum tunneling!

Wave-Particle Duality: This principle in quantum mechanics suggests that all particles also have properties of waves, which is why they can "tunnel" through barriers.

Quantum Mechanics: The branch of physics dealing with atomic and subatomic systems, providing the framework for understanding phenomena like quantum tunneling.

Heisenberg Uncertainty Principle: A fundamental concept in quantum mechanics stating that it's impossible to simultaneously know both an electron’s position and momentum accurately - this uncertainty allows for phenomena like quantum tunneling.
