A theory developed out of the University of Sydney (USyd) has been successfully demonstrated by engineers at the University of New South Wales (UNSW), a joint research paper has detailed. Calling it a "world-record result", USyd said the experimental result saw the reduction of errors in semiconductor "spin qubits" -- quantum bits -- which are a type of building block for quantum computers. A spin qubit is a quantum bit that encodes information based on the quantised magnetic direction of a quantum object, such as an electron. The experiment demonstrated error rates as low as 0.043%, which the pair of universities said was lower than any other spin qubit. The result was achieved using the theoretical work of quantum physicists at USyd's Nano Institute and School of Physics and performed by UNSW engineers.
