Simple is beautiful in quantum computing

Quantum computing could solve problems impossible for today's supercomputers. The challenge for this new form of computing is processing the quantum bits (qubits) that represent data. A qubit can be made by controlling the orientation of an electron's spin at a defect site in diamond. To solve a problem, a quantum computer uses logic gates to couple multiple qubits and output new information. Scientists designed a new protocol that can be used to develop fast, robust logic gates for qubits. The ...
