We study a system consisting of three identical two-level atoms where two atoms are assumed to be close to each other such that they interact via the dipole-dipole interaction while the third atom is located at a distance d ≫ λ, with λ the atomic transition wavelength. Although the distant third atom does not directly interact with the collective two-atom subsystem, it can be used to alter the total system’s spontaneous emission properties via measurement-induced entanglement. We present a detection scheme for which Glauber’s third-order photon correlation function displays an oscillatory behavior in time, with a frequency determined by the coherent coupling parameter of the dipole-dipole interaction between the first two atoms. This parameter crucially depends on the two-atom separation allowing to resolve the distance between the two adjacent atoms with sub-Abbe resolution.
