Scanning tunneling microscopy was used for the quantum tunneling of single hydrogen atoms. Inelastic electron tunneling spectroscopy was used to detect the vibrations of the individual hydrogen atoms against the copper surface. The variable temperature measurements of the hydrogen atom diffusion, showed a transition from thermally activated diffusion to quantum tunneling at 60 K temperature.
