Taco Cowboy writes "De Beers' ad slogan "A diamond is forever" may need some upgrading for someone has created a quantum computer inside a diamond
A team that includes scientists from USC has built a quantum computer in a diamond, in order to protect it against "decoherence" — noise that prevents the computer from functioning properly
The team's diamond quantum computer system featured two quantum bits (called "qubits"), made of subatomic particles
Like all diamonds, the diamond used by the researchers has impurities — things other than carbon. The more impurities in a diamond, the less attractive it is as a piece of jewelry, because it makes the crystal appear cloudy. The team, however, utilized the impurities themselves.
A rogue nitrogen nucleus became the first qubit. In a second flaw sat an electron, which became the second qubit. To put it more accurately, the "spin" of each of these subatomic particles was used as the qubit."
