Rydberg-atom-based single-photon detection for haloscope axion searches

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 b...

Summary: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.
