Three Electrons Entangled

Posted by chrisd on from the happy-particles-of-fate dept.

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.""

    Wow! A real orgy! Now which States, exactly, is this legal in?

    I'm all for electron entanglement, as long as Ashcroft doesn't decide it's drug paraphernalia. I mean, after all, if one of those electrons was ever part of 9,1-tetrahydracannabinol (did I get that right?)...

    I remember a Bill Cosby skit about this subject. It went something like this:

    God: "I want you to build a quark."
    Noah: "Right... what's a quark?"
    God: " Make it 300 qubits by 80 qubits by 40 qubits."
    Noah: "Right... what's a qubit?"

    "I'm feeling a bit down today."

    The other two respond, "Wow, that really puts a whole new spin on things."

      Well the electron only said he was "feeling a bit down" ...=P

      I find it humorous that you're willing to tear apart my already-lame joke on something like whether the electron was "feeling" down or claiming to actually "be" down (which he wasn't), whilst completely ignoring the fact that these electrons are feeling and talking to a bartender in the first place, the more obvious impossibilities. ;)

    No. Since the three of them are entangled, they all collapse together when one is measured. The important thing about this article is that you need many entangled electrons to make most complicated calculations, the same way you want many logic gates connected to each other in a computer.

    ...it got "weird", and now the three electrons are not talking to each other.
