Diamond Quantum Computer System
A group of researchers including the USC Professor Daniel Lidar and USC postdoctoral researcher Zhihui Wang, as well as researchers from the Delft University of Technology in the Netherlands, Iowa State University and the University of California have managed to design a quantum computer in a diamond. The small quantum computers cannot yet compete with the speed of larger, traditional computers, though unlike gas- and liquid-state systems, the solid-state quantum computers can be easily scaled up in size and thus might represent the future of quantum computing. The solid-state computing systems have existed before, but this computer is the first to feature decoherence protection (protection from noise that prevents a computer from functioning properly). The team’s diamond quantum computer system features two quantum bits, called “qubits”, which unlike traditional computer bits encoding distinctly either a one or a zero, can encode a one and a zero at the same time.
