- Abstract summary: We present a method for manipulation and readout of the state of trapped clouds of ultra-cold bosonic atoms.
We discuss the creation of coherent and squeezed states of quasiparticles and the coupling of quasiparticle modes through an external cavity field.
This enables operations like state swapping and beam splitting which can be applied to realize a Mach-Zehnder interferometer (MZI) in frequency space.

- Abstract: Ensembles of ultra-cold atoms have been proven to be versatile tools for high
precision sensing applications. Here, we present a method for manipulation and
readout of the state of trapped clouds of ultra-cold bosonic atoms. In
particular, we discuss the creation of coherent and squeezed states of
quasiparticles and the coupling of quasiparticle modes through an external
cavity field. This enables operations like state swapping and beam splitting
which can be applied to realize a Mach-Zehnder interferometer (MZI) in
frequency space. We present two explicit example applications in sensing: the
measurement of the healing length of the condensate with the MZI scheme, and
the measurement of an oscillating force gradient with a pulsed optomechanical
readout scheme. Furthermore, we calculate fundamental limitations based on
parameters of state-of-the-art technology.

We present a method to prepare non-classical states of the electromagnetic field in a microwave resonator.
It is based on a controlled gate that applies a squeezing operation on a SQUID-terminated resonator conditioned on the state of a dispersively coupled qubit.
We explore the use of this tool to map an arbitrary qubit state into a superposition of squeezed states.

Atomic superfluids formed using Bose-Einstein condensates (BECs) in a ring trap are being investigated in the context of superfluid hydrodynamics, quantum sensing and matter-wave interferometry.
Recent studies have proposed coupling the ring BEC to optical cavity modes carrying orbital angular momentum to make minimally destructive measurements of the condensate rotation.
We present a detailed theoretical analysis to demonstrate that the use of squeezed light and backaction evasion techniques allows the angular momentum of the condensate to be sensed with noise well below the standard quantum limit.

We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator.
This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.
