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.
Through the company Silicon Quantum Computing, this has been Australia's national quantum computing focus.

Nuclear Magnetic Resonance (NMR) quantum computing is a type of quantum computing that uses the principles of nuclear magnetic resonance to manipulate quantum bits, or qubits. In this approach, the states of qubits are represented by the nuclear spins of atoms (often isotopes like carbon-13, nitrogen-15, or phosphorus-31) within a molecule.
