Description
QUAntum LImited PHotons In the Dark Experiment (QUALIPHIDE) utilizes novel receivers and detectors operating in the microwave to far infrared to search of Hidden Photons (HP). HPs are a candidate for wave like dark matter. Searches with quantum sensing techniques enables exploring new phase space for both HPs and axion like particles. The first version of QUALIPHIDE was done in the microwave with traveling wave parametric amplifiers. Now, we are probing deeper than standard quantum limit searches by using photon counting. This new iteration of QUALIPHIDE will operate in 8-16 THz (~50 meV hidden photon masses), with expected sensitivity of kinetic mixing ~10^-12. Our work focuses on the sensors, as we enable their reach with mHz dark count rates, and eventually towards operation at ~1 THz.
