In this talk I will provide a gentle introduction to the recent advances on the use of scanning tunnelling microscope (STM) electrically to drive and detect spin resonance of individual atomic spins on surfaces. This new technique has made it possible to probe individual nuclear spins with STM, among other feats. I will discuss the theory of several physical mechanisms that account for the coupling of electric fields to spins in this system . I will also briefly discuss what are the prospects for using adatom spins as qubits, given the the recently reported coherent manipulation of adatom spins .
