Accelerating the search for axions with entangled cavity states
ORAL
Abstract
Haloscopes are tunable microwave-cavity devices used to search for axionic dark matter by resonantly converting it to fluctuations in the electromagnetic field. While haloscopes have already successfully excluded several ranges of possible axion masses, a comprehensive search is hindered by noise at or near the standard quantum limit. Here, we present design, simulations, and initial tests of a novel haloscope concept utilizing entangled states between two microwave cavities, capable of increasing the rate at which haloscopes can search for the axion by 20x.
