On Diamond-Based Quantum Computing

Roland Piquepaille writes "Quantum computing is usually associated with extremely low temperatures. Physicists at Harvard University have shown that diamonds can be used to create stable quantum computing building blocks at room temperature. A nitrogen vacancy in diamond could lead to quantum registers able to store or retrieve data. '"The problem is, what makes single nuclear spin so stable - its weak interaction with its surroundings - also prevents us from directly manipulating it," Lukin says. "How do you control something that can't interact with anything?" You do it gingerly and indirectly, the Harvard physicists report in Science. They found that nuclear spins associated with single atoms of carbon-13 - which make up some 1.1 percent of natural diamond - can be manipulated via a nearby single electron whose own spin can be controlled with optical and microwave radiation.'"

  1. HARDEST METAL KNOWN TO MAN by Anonymous Coward · · Score: -1, Offtopic

    Due to extensive research done by the Fourchon University of Science, diamond has been confirmed as the the hardest metal known the man. The research is as follows.

    Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed.

    They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an out into the wall, and the wall came out fine.

    They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors.

    They crashed 400 miles per hour into a diamond traveling at iron car. Western New York was powerless for hours.

    They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards midwestern Prussia at 400 billion miles per hour.

    They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused two wayward airplanes to lose track of their bearings, and make a fatal crash with two buildings in downtown New York.

    They spun 400 miles at diamond into iron per wall. The results were inconclusive.

    Finally, they placed 400 diamonds per hour in front of a car made of wall traveling at miles, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known to man.
