Quantum entanglement is where it's at. Can't hack it if it uses magic ✨

Except no one has figured out how to communicate properly with entanglement.

It's easy. You just need a second line of communication to share which spin your source particle has and then they know which spin the entangled one has.

I too used to think this. There are lots of videos online that can and do explain how and why that doesn't work much better than I can.

People much more intelligent than you or I have attempted to solve this problem and failed. I challenge you to find a peer reviewed video of article explaining how it does work if you don't believe me.

It was a joke - if you always communicate the particle state it defeats the purpose of having the particles.

Alright then. Thought you were the one who downvoted me so thought you were serious.

You can't. If you could it would break the speed of causality and that would be a very big no no in terms of the laws of physics as we understand them.

Oh good, quantum stuff gets even more weird

(paraphrasing Sean Carroll from memory here)

As I understand it, even though the action is instantaneous over distance due to entanglement, because neither party can communicate this to the other, information isn’t traveling faster than the speed of light.

Then how did he explain it as one of the particles can be many light years away and know the Planck time moment it's mated pair changes.?


kindle139 t1_jegjh8r wrote

I don’t know, I think he might say something like if you look at the equations then you can see that distance is not a relevant factor.

That's why Einstein hated the idea so much, it broke one of his fundamental laws.
