Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

Scientists have demonstrated a new method for measuring how long ultrashort events like quantum tunneling to occur at quantum scale time.

In this experiment I show you to perform quantum tunneling. I first explain what quantum tunneling actually is, then I show you how to make it happen. I talk about total internal reflection and how ...
