Well then set up two particles on opposite sides of the planet and send communications via this entanglement at the speed of.. light?
And yes, I have near zero knowledge of particle physics!

- skybrian 7y agoThe mathematics of entanglement doesn't allow it to be used for communication.
- shdh 7y agoWhat specifically prevents entanglement for being used in communication?
- ksaj 7y agoEinstein described quantum mechanics as "spooky" because of the __instantaneousness__ of the apparent remote interaction...
- coolio2657 7y agoBasically, what skybrian has, in a rather short way, said. As far as I have been able to find out over the years, quantum entanglement "does" operate at speeds greatly exceeding that of the speed of light, but, because of the weird properties of quantum mechanics, no "operation" that could ever be used to transfer data between two sets of particles is possible. So while they "are" entangled, they are apparently not entangled enough in a stable way such that a change to atom A would be picked up as a new change to atom B (thus, having successfully transferred some sort of information), because the quantum state breaks down somehow.
