SUMMARY:Achieving the Ultimate Timing Resolution\, Wisconsin Quantum I
 nstitute\, Luis Sanchez-Soto\, Complutense University of Madrid
DESCRIPTION:Measuring small separations between two optical sources\, 
 either in space or in time\, constitutes an important metrological cha
 llenge. 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 a
 rbitrarily small separations with quantum-limited precision. This has 
 been demonstrated in the lab\, both in the spatial and the temporal do
 main. However\, the question of whether the optical coherence brings a
 ny metrological advantage to mode projections is still a point of deba
 te. Here\, I will discuss this problem and show new experiments puting
  forwards the effect of varying coherence on estimating the temporal s
 eparation between two single-photon pulses.
