"Essentially quantum entanglement suggests that acting on a particle here can instantly influence a particle far away, something that is often described as theoretical teleportation. And the implications are HUGE for quantum mechanics and quantum computing. But if it's so complicated that not even Einstein could get his head around it, how do you explain it on YouTube?
As Morello shows in this fantastic video, the best way is to first explain what it's not: classical correlation. And this can be done using a simple piece of paper and a red and blue text."
