Imaging a donor-based quantum dot wavefunction in silicon

Spins in silicon have proven to be a suitable platform for the development quantum technologies. Understanding and controlling spin coupling is now a formidable challenge to overcome. In this talk our most recent results will be reviewed, where atomic scale STM fabrication is combined with low temperature donor imaging to enable local measurements of quantum dots in the STM. This technique will allow manipulation and local read-out of donor states, beneficial from the understanding of qubit coupling in quantum computation to the topological properties of large scale complex arrays of spins.
