We propose a table-top experiment to search for axions and
axion-like-particles in the galactic halo using quantum-enhanced
interferometry. This proposal is related to the previously reported ideas
(Phys. Rev. D 98, 035021, Phys. Rev. Lett. 121, 161301, Phys. Rev. D 100,
023548) but searches for axions in the mass range from $10^{-17}$ up to
$10^{-7}$ eV using two coupled optical cavities. We propose to further enhance
the sensitivity of the experiment using squeezed states of light similar to the
gravitational-wave detectors. Our layout can be implemented as a table-top
experiment and then further scaled to a multi-km long detector. We show that
such an instrument has the potential to set constraints of the axion-photon
coupling coefficient of $10^{-18}$ GeV$^{-1}$ for axion masses of $10^{-17}$ eV
or detect the signal.
