- Abstract: We use time-frequency continuous variables as the standard framework to
describe states of light in the subspace of individual photons occupying
distinguishable auxiliary modes. We adapt to this setting the interplay between
metrological properties and the phase space picture already extensively studied
for quadrature variables. We also discuss in details the Hong-Ou-Mandel
interferometer, which was previously shown to saturate precision limits, and
provide a general formula for the coincidence probability of a generalized
version of this experiment. From the obtained expression, we systematically
analyze the optimality of this measurement setting for arbitrary unitary
transformations applied to each one of the input photons. As concrete examples,
we discuss transformations which can be represented as translations and
rotations in time-frequency phase space for some specific states.
