Abstract

Due to the position-dependent atom-field interaction, the position information of the atom in the standing-wave fields can be obtained by means of the phase-sensitive excited state population. More importantly, the maximal probability of finding an atom within the sub-half-wavelength domain of the standing waves can reach 100 %. Thus, our scheme may be helpful in observing precision quantum measurement and computation for quantum information processing.
