| contents | The Rayleigh's criterion infamously imposes a minimum separation between two incoherent sources for them to be distinguishable via classical methods. In this work, we demonstrate the emergence of two-photon beats from the interference of a single reference photon and a photon coming from one of two transversally displaced incoherent sources. We also show that, apart from a factor of two, the ultimate quantum precision in the estimation of any value of the distance between two thermal sources is achievable independently of the wavepacket spatial structure, by performing a relatively low number of sampling measurements of the transverse momenta of the interfering photons, without the need of any additional optics. The feasibility of this technique makes it an optimal candidate to important applications in microscopy, astronomy and remote sensing |
