Hyper-Entangled Brains

Hyper-Entangled Photons --'Superdense' Coding Gets Denser - Slashdot

Advances in particle science like this one are what make me happy to wake up in the morning. The idea of quantum entanglement (or as Einstein put it, "spooky action at a distance") is that you have a pair of subatomic particles whose properties are related to each other. If one particle has an up spin then the other has a down spin. Now take those particles and separate them by a thousand miles. Would the same relation apply? As far as experimentation has show, yes, the relation remains, meaning that information such as whether a particle is to spin up or down can travel faster than the speed of light. It seems that hyper-entanglement involves several particles all arranged together and then given an appropriate separation. And the results are that the same relation between a single pair of particles can also apply to multiple particles. The implications are staggering, from true teleportation to the sending of encrypted data to multi-line processing in computer chips. Hyper-entanglement could go even larger, to the point that our entire universe might have a hyper-entanglement with another universe where changes in either universe are reflected in the other universe. Amazing stuff really and I love it.
