Let’s Begin…

The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms). One great example of quantum physics’ weirdness can be shown in the Schrödinger's cat thought experiment. Josh Samani walks us through this experiment in quantum entanglement.

Quantum entanglement turns out to be useful in fields like quantum cryptography where scientists study ways in which information can be securely shared. Can you think of a way that you could use entanglement to perform a useful task?
