SYDNEY, Sept. 25 (Xinhua) -- An Australian nanotech startup has demonstrated that its silicon-based quantum computer chips can be mass-produced with high accuracy.
The quantum processors of Diraq, a startup of Australia's University of New South Wales (UNSW), consistently perform with exceptional accuracy in an industrial production environment, according to a UNSW statement released Thursday.
Diraq has shown its quantum chips aren't just lab-perfect prototypes. They can be manufactured in an industrial setting, maintaining the 99 percent accuracy needed to make quantum computers viable, it said.
Published in Nature, the research was in collaboration with Belgium-based European nanoelectronics institute Interuniversity Microelectronics Center (IMEC).
Together they demonstrated the Diraq-designed, IMEC-fabricated chips worked just as reliably coming off a semiconductor chip fabrication line as they do in the experimental conditions of a research lab at UNSW, the statement said.
Achieving over 99 percent fidelity in two-qubit (quantum bits) operations marks a key milestone for Diraq's quantum processors to achieve utility scale, the point at which a quantum computer's commercial value exceeds its operational cost, it said. ■
