Rydberg single photon detection for probing 0.1-10 meV dark matter with BREAD

Author(s): Abhishek Banerjee, Reza Ebadi, and Surjeet RajendranWe introduce a Rydberg-based single photon detector (SPD) for probing dark matter in the 0.1–10 meV mass range (20 GHz–2 THz). The Rydberg SPD absorbs photons produced and focused by the BREAD dish antenna and trades them for free, detectable electrons. At the lower end of the mass range, photons dr…[Phys. Rev.
