- Abstract: We show that squeezing is a crucial resource for interferometers based on the
spatial separation of ultra-cold interacting matter. Atomic interactions lead
to a general limitation for the precision of these atom interferometers, which
can neither be surpassed by larger atom numbers nor by conventional phase or
number squeezing. However, tailored squeezed states allow to overcome this
sensitivity bound by anticipating the major detrimental effect that arises from
the interactions. We envisage applications in future high-precision
differential matter-wave interferometers, in particular gradiometers, e.g., for
gravitational-wave detection.

We develop and investigate an integrated multimode two-colour SU (1,1) interferometer that operates in a supersensitive mode.
By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern.
We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*104$ photons are generated.
