The feasibility of creating and manipulating coherent quantum states on surfaces of functionalized semiconductor nanostructures is computationally investigated. Quantum dynamics simulations of electron-hole transfer between catechol molecules adsorbed on TiO_2 -anatase nanostructures under cryogenic and vacuum conditions indicate that laser induced coherent excitations can be prepared and manipulated to exhibit controllable spatial Rabi oscillations. The presented computational methods and results are particularly relevant to explore the basic model components of quantum-information electro-optic devices based on inexpensive and readily available semiconductor materials.
