sqc.com.au/2024/02/08/silicon-quantum-computing-demonstrates-high-fidelity-initialisation-of-nuclear-spins-in-a-4-qubit-device/ points to one of their papers: www.nature.com/articles/s41565-023-01596-9 High-fidelity initialization and control of electron and nuclear spins in a four-qubit register
Their approach seems to be more precisely called: Kane quantum computer and uses phosphorus embedded in silicon.
They come from the University of New South Wales.
