The axion particle, a consequence of an elegant hypothesis that resolves the strong-CP problem of quantum chromodynamics, is a plausible origin for cosmological dark matter. In searches for axionic dark matter that detect the conversion of axions to microwave photons, the quantum noise associated with microwave vacuum fluctuations will soon limit the rate at which parameter space is searched. Here we show that this noise can be partially overcome either by squeezing the quantum vacuum using… 
Searching for Dark Matter with a Superconducting Qubit.
A novel microwave photon counting technique and a new exclusion limit on hidden photon dark matter are reported and a demonstrated noise reduction technique enables future dark matter searches to be sped up by a factor of 1,300.
Status of the HAYSTAC Experiment
Dark matter axions may be detected by their resonant conversion to photons in a tunable microwave cavity permeated by a strong magnetic field. HAYSTAC (Haloscope At Yale Sensitive To Axion Cold dark

A cavity entanglement and state swapping method to accelerate the search for axion dark matter
In cavity-based axion dark matter detectors, quantum noise remains a primary barrier to achiev-ing the scan rate necessary for a comprehensive search of axion parameter space. Here we introduce a

We introduce the concept of impedance matching to axion dark matter by posing the question of why axion detection is difficult, even though there is enough power in each square meter of incident
Proposal for gravitational direct detection of dark matter
The only coupling dark matter is guaranteed to have with the standard model is through gravity. Here we propose a concept for direct dark matter detection using only this gravitational coupling. We
