  We propose a versatile quantum sensing protocol based on two dissipatively
coupled distant atoms embedded as impurities in a two-dimensional
sub-wavelength atomic array. The array acts as a waveguide for the emitter
light, creating cooperative enhancement that allows for more efficient
population transfer. By monitoring the population of one of the impurity atoms,
it is possible to detect frequency shifts in the emitters' resonance
frequencies. We analytically estimate achievable sensitivities as well as the
dependence on various system parameters. The proposed protocol is robust
against various environmental factors and perturbations, which enhances its
applicability in real-world scenarios.
