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.'"
optical radiation? so. . like cyclops rays or something?
If you are about to mod me down, keep in mind that this post was most likely sarcastic.
Nothing says I love you like a diamond quantum computer.
When computers are built with this technology, their prices will no longer tumble every 18 months! In fact, they will eventually become precious collectibles.
