Accurate measurement of the position of an atom has been a problem of interest ever since the thought experiment posed by Werner Heisenberg through the so-called Heisenberg’s microscope. Modern quantum optical techniques have made it possible to realize such a device giving birth to the field of atom localization. In the last couple of decades the techniques have matured enough to offer atom localization along all three spatial dimensions in the subwavelength domain. Furthermore, ideas behind atom localization are general enough to apply to other fields requiring precise control or measurement of the position of atom-like entities such as microscopy, nano-lithography, optical trapping of atoms, optical lattices, and atom optics. I will discuss why such methods work in the context of the Rayleigh limit of resolution and review the progress in the field of atom localization both on the theoretical and experimental front. |
