Researchers at the University of New South Wales (UNSW) and the University of Melbourne have designed a 3D silicon chip architecture based on single atom quantum bits, providing a blueprint to build a large-scale quantum computer.
Scientists and engineers from the Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology, headquartered at UNSW, are leading the world in the race to develop a scalable quantum computer in silicon – a material favoured by the trillion-dollar computing and microelectronics industry.
Teams led by UNSW researchers have already demonstrated a unique fabrication strategy for realising atomic-scale devices and have developed the world’s most efficient quantum bits in silicon using either the electron or nuclear spins of single phosphorus atoms. Quantum bits – or qubits – are the fundamental data components of quantum computers.
This breakthrough has launched the research team over one of the final hurdles in their mission. They now know exactly what is required to scale up to an operational quantum computer; something that many others around the world are trying to achieve.
