  Phase super-sensitivity is obtained when the sensitivity in a phase
measurement goes beyond the quantum shot noise limit, whereas super-resolution
is obtained when the interference fringes in an interferometer are narrower
than half the input wavelength. Here we show experimentally that these two
features can be simultaneously achieved using a relatively simple setup based
on Gaussian states and homodyne measurement. Using 430 photons shared between a
coherent- and a squeezed vacuum state, we demonstrate a 22-fold improvement in
the phase resolution while we observe a 1.7-fold improvement in the
sensitivity. In contrast to previous demonstrations of super-resolution and
super-sensitivity, this approach is fully deterministic.
