Axions are hypothetical pseudoscalar particles that naturally arise in
the Peccei-Quinn solution to the strong CP problem in QCD, and at the
same time provide one of the most compelling candidates for dark
matter. Among the various experimental approaches being pursued
worldwide, microwave cavity experiments are particularly well suited
to probe axions in the GHz frequency range.
Recent advances in quantum sensing offer a unique opportunity to
surpass the standard quantum limit, potentially extending the reach of
these experiments by orders of magnitude. Building on these
developments, the DarkQuantum project, in collaboration with RADES, is
developing a microwave cavity coupled to a superconducting transmon
device to detect the photons produced by axion conversion, operating
in the single-photon detection regime. In this contribution, we will
present the project concept and report first experimental results,
highlighting the promise of this technique for future dark matter
searches.
