They have demonstrated an integrated silicon qubit platform that combines both single-spin addressability—the ability to 'write' information on a single spin qubit without disturbing its neighbours—and a qubit 'read-out' process that will be vital for quantum error correction.

Moreover, their new integrated design can be manufactured using well-established technology used in the existing computer industry.
