The HAYSTAC team, including Assistant Professor Danielle Speller, have published a paper in Nature reporting on the use of novel new technology they have developed to increase our power to search for one of the most likely candidates for dark matter, axions. The team used vacuum squeezing to circumvent the quantum limit in a search for dark matter. Breaking through the quantum limit invites an era of fundamental physics searches in which noise reduction techniques yield unbounded benefit compared with the diminishing returns of approaching the quantum limit.
