abstract

We propose a Rydberg-atom-based single-photon detector for signal readout in dark matter haloscope experiments between 40 ${\mu}$eV and 200 ${\mu}$eV (10 GHz and 50 GHz). At these frequencies, standard haloscope readout using linear amplifiers is limited by quantum measurement noise, which can be avoided by using a single-photon detector. Our single-photon detection scheme can offer scan rate enhancements up to a factor of $10^4$ over traditional linear amplifier readout, and is compatible with many different haloscope cavities. We identify multiple haloscope designs that could use our Rydberg-atom-based single-photon detector to search for QCD axions with masses above 40 ${\mu}$eV (10 GHz), currently a minimally explored parameter space.

  1. Three-dimensional trapping of circular Rydberg atoms by a superimposed vortex light beam

    physics.atom-ph 2025-08 conditional novelty 6.0 of 10

    A counterpropagating pair of opposite-charge Bessel vortex beams creates a three-dimensional ponderomotive lattice that can confine circular Rydberg atoms at its intensity minima.

  2. Search for dark-matter axions beyond the quantum limit: the Cosmological Axion Sarov Haloscope (CASH) proposal

    hep-ph 2025-06 conditional novelty 6.0 of 10

    The CASH haloscope proposal projects that Josephson-junction single-photon detectors can reach axion-photon couplings below 1e-15 GeV^-1 in the 38-54 micro-eV mass range, beating the standard quantum limit.
