  Quantum control techniques play an important role in manipulating and
harnessing the properties of different quantum systems, including isolated
atoms. Here, we propose to achieve quantum control over a single on-surface
atomic spin using Landau-Zener-St\"uckelberg-Majorana (LZSM) interferometry
implemented with Scanning Tunneling Microscopy (STM). Specifically, we model
how the application of time-dependent, non-resonant AC electric fields across
the STM tip-surface gap makes it possible to achieve precise quantum state
manipulation in an isolated Fe atom on a MgO/Ag(100) surface. We propose a
protocol to combine Landau Zener tunneling with LZSM interferometry that
permits one to measure the quantum spin tunneling of an individual Fe atom. The
proposed experiments can be implemented with ESR-STM instrumentation, opening a
new venue in the research of on-surface single spin control.
