The actual location of an atom in three-dimensional (3D) space is described by spatial-dependent atom-field interaction, which has potential applications in many fields, including optical imaging techniques, 3D nanolithograghy, Bose–Einstein condensation, and dual-measurement of center-of-mass wave function. Here, we propose a scheme to realize single atom localization in 3D space based on double-channel interactions. By exploiting the property of the spontaneously emitted photon, high-precision 3D atom localization, such as sphere-like patter...
