An international team of researchers (Australia, the Netherlands, Japan, USA – industry) has demonstrated an integrated device platform incorporating a silicon metal-oxide-semiconductor double quantum dot that is capable of single-spin addressing and control via electron spin resonance, combined with high-fidelity spin readout in the singlet-triplet basis. They have shown that they can combine this with a special type of quantum readout process known as Pauli spin blockade, a key requirement for quantum error correcting codes that will be necessary to ensure accuracy in large spin-based quantum computers. The new integrated design can be manufactured using well-established technology used in the existing computer industry…read more. Open Access TECHNICAL ARTICLE
