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.""

"These devices will offer enormously enhanced computing power"

Promises, promises. They've been saying that since at least the 80s. This is vaguely reminiscent of the AI (Turing Test) story a few days ago.

Sure, they can factor the number 15 (or so they claim), but I know a counting horse who can do the same.

YAW.
