Watch the Best Explanation for Quantum Entanglement Ever Given

Quantum entanglement is really cool. It's also really hard to understand. It allows us to transfer "information" "instantaneously" across vast distances. Hypothetically, we could use quantum entanglement in communication and other technological applications.

This video takes quantum entanglement, explains it in terms you're already familiar with, and then elaborates on the quantum aspect. It's one of the best explanations for quantum entanglement on YouTube and is narrated by Andrea Morello from the University of New South Wales.
