Three Electrons Entangled

An anonymous reader writes "Science Blog reports on Michigan researchers who have managed to entangle three electrons at once. "The quantum entanglement of three electrons, using an ultrafast optical pulse and a quantum well of a magnetic semiconductor material, has been demonstrated in a laboratory at the University of Michigan, marking another step toward the realization of a practical quantum computer. While several experiments in recent years have succeeded in entangling pairs of particles, few researchers have managed to correlate three or more particles in a predictable fashion.""

Quantum Teleportation?

[bill_mcgonigle]

So does this mean you can now do Quantum Teleportation without destroying the original? Well, the original could be momentarily destroyed, but if you have a second entangled particle you can rebuild it almost instantly, so it's like it's never destroyed. For all I know it wouldn't surprise me if you could destroy the particle after it's been recreated, seeing how quantum physics exists primarily to remind me how dumb I really am.
