Via quantum interference mechanisms, we exhibit precise atomic positioning by utilizing the strong electromagnetic field confinement and enhanced near field interactions inherent to (SPPs). Our model employs specialized probe and control fields to generate spatially dependent absorption, thereby facilitating atomic localization with nanometer scale precision. We have identified sharply defined localization patterns that are regulated by phase modulation and detuning parameters through comprehensive numerical simulations. The conventional diffraction limit is effectively overcome by the coupling between (SPP) modes and atomic states, while quantum coherence is maintained. These findings provide practical implications for applications in plasmon enhanced spectroscopy, nanolithography, and atomic trapping, as they open new frontiers for quantum-scale manipulation. Additionally, we establish the optimal operational parameters that optimize spatial resolution and suppress decoherence in plasmonic nanostructures.
