What is quantum entanglement?

409 viewsOtherPhysics

My husband is watching YouTube and there’s a man discussing quantum entanglement.

His description: There are two particles. They can be either green or red, but they are both colors until they’re measured. Once you measure one, though, it automatically determines that the other is the same. No matter how many times you measured, or how far you separated the particles, the two would always be the same color.

Why does one being one color guarantee that the other one would be? How do they “know” to always be that color? And what sort of implication does that have for science/real world, other than being really cool?

Quantum Entanglement is really fucking weird and not fully understood yet. The idea is that if you do some special trickery to two or more atoms, they become sort of “linked” together in such a way that all their properties are now related to their partner’s properties. The why is even more complicated so we’ll leave that there.

Now that you have 2 or more atoms linked together, you can move them all around in space and different speeds and any other way you can think of. No matter how far apart these partners are, you will ALWAYS be able to determine the state of the other simply based on the one in front of you.

To be clear, this is not a transference of information. It’s more like we’re deducing from really far away.
