Abstract
We present the design and status of a detector to search for axions and axion-like particles in the galactic halo using quantum-enhanced interferometry. The operating principle is related to previously reported ideas, but aims for axions in the mass range from 10−16 eV up to 10−8 eV. We also show how to apply squeezed states of light to enhance the sensitivity similar to the gravitational-wave detectors. This experiment has the potential to be further scaled up to a multi-kilometre long detector and to then set constraints of the axion-photon coupling coefficient of ∼ 10−18 GeV−1 for axion masses of 10−16 eV, or detect a signal.
