I do believe there have been experiments that have successfully transmitted data via quantum entanglement.
I don't really feel like digging up a source at the moment though.
- Ralith 16y agoWait, what? Instantaneously?
- teilo 16y agoYes. Instantaneously. Always. But this fact cannot be used to transfer information from point A to point B instantaneously. Nothing ever discovered in the weird world of quantum entanglement allows information to exceed the speed of light.
- Ralith 16y agoNo, I know entanglement changes are instantaneous, I just thought exactly what you're confirming; that you can't communicate with it.
- splat 16y agoNo data is ever transmitted via quantum entanglement (at least, data from the perspective of the observer). Entanglement is simply when two particles exist in the same quantum state. (Or, to be more precise, in the same superposition of quantum states.) When the state is observed (say, an experimenter examines one of the particles), then the entire wavefunction collapses to a single quantum state. The two particles in the system therefore collapse to the same state instantaneously, but no information can ever be transmitted in this way.
