Quantum Computer Built Inside a Diamond

 USC News (04/04/12) Robert Perkins

University of Southern California (USC) scientists and a team of researchers have built a quantum computer in a diamond to demonstrate the viability of solid-state quantum computers.  The quantum computing system featured two quantum bits, known as qubits, made of subatomic particles.  The researchers took advantage of the impurities in the diamond, using a rogue nitrogen nucleus as the first qubit, and a flawed electron as the second qubit.  The researchers say the diamond-based quantum computer is the first to incorporate decoherence protection, using microwave pulses to continually switch the direction of the electron spin rotation.  The researchers demonstrated that the diamond-incased system operates in quantum fashion by seeing how closely it matched Grover’s algorithm, which is a search of an unsorted database.  Their system was able to find the correct answer as part of Grover’s algorithm on the first attempt about 95 percent of the time.  The researchers say the future of quantum computing may reside in solid-state quantum computers because they can be easily scaled up in size, in contrast to earlier gas- and liquid-state systems.
