- Abstract: Measuring small separations between two optical sources, either in space or in time, constitutes an important metrological challenge. Standard intensity detection fails for vanishing separations, as quantified by the time-honored Rayleigh's criterion. Recently, it has been established that appropriate mode projections can appraise arbitrarily small separations with quantum-limited precision. This has been demonstrated in the lab, both in the spatial and the temporal domain. However, the question of whether the optical coherence brings any metrological advantage to mode projections is still a point of debate. Here, I will discuss this problem and show new experiments puting forwards the effect of varying coherence on estimating the temporal separation between two single-photon pulses.
