First Quantum Computing Gate on a Chip

Posted by Zonk on from the next-advance-is-really-tiny-stargates dept.

An anonymous reader writes "After recent success in using quantum computing for superconducting qubits, researchers from Delft have formed the first Controlled-NOT quantum gate. 'A team has demonstrated a key ingredient of such a computer by using one superconducting loop to control the information stored on a second. Combined with other recent advances, the result may pave the way for devices of double the size in the next year or two--closer to what other quantum computing candidates have achieved, says physicist Hans Mooij of the Delft University of Technology in the Netherlands. Unlike today's computers, which process information in the form of 0s and 1s, a quantum computer would achieve new levels of power by turning bits into fuzzy quantum things called qubits (pronounced cue-bits) that are 0 and 1 simultaneously. In theory, quantum computers would allow hackers to crack today's toughest coded messages and researchers to better simulate molecules for designing new drugs and materials.'"

  1. Double the size of a single not gate? by Spazntwich · · Score: 5, Funny

    I know grammar has been taking a hit in society as of late, but now even our computers are blatantly spewing out double negatives?

    We're not in for an unrough ride, gentlemen.

  2. They say that it works by zmollusc · · Score: 4, Funny

    but how can they test it when the output is always either 0, meh, pfft or 1?

    They're opening the quantum gates now? They're insane! Who knows what might pour out of them... I hope they're at least doing it on the moon.

    The future of the human race is up to one lone marine now. Thanks a lot, scientists.

    but it was my understanding that there are 32 quantum states of electrons, not just on/off (1/0) like in the binary computer world. So, if we now have a quantum NOT gate, doesn't that mean there are 32 possible states of the NOT gate? Well, yes and no...

    At home you will use these for ever more sophisticated rendering of artificially intelligent virtual reality porn.

    At work it will be more useful in the advanced simulation of a mechanical process for imprinting letter glyphs on sheets of wood fiber.

    Hmm, seems like they've successfully performed a NOT on Moore's law.

    There will be a small market. I think the world needs only 5 or so quantum computers.
