World-Record in Reducing Errors in Spin Qubits Announced

(ScienceDaily) A world-record result in reducing errors in semiconductor electron ‘spin qubits’, a type of building block for quantum computers, was announced by the University of Sydney Nano Institute and School of Physics and University of New South Wales in the Nature Electronics cover story for April.
“Reducing errors in quantum computers is needed before they can be scaled up into useful machines,” said Professor Stephen Bartlett, a corresponding author of the paper. “Once they operate at scale, quantum computers could deliver on their great promise to solve problems beyond the capacity of even the largest supercomputers. This could help humanity solve problems in chemistry, drug design and industry.”
