Sensitive qubit-based technique to accelerate search for dark matter

The blue cylinder in this diagram represents a superconducting microwave cavity used to accumulate a dark matter signal. The purple is the qubit used to measure the state of the cavity, either 0 or 1. The value refers to the number of photons counted. If the dark matter has successfully deposited a photon in the cavity, the output would measure 1. No deposition of a photon would measure 0. Credit: Akash Dixit, University of Chicago
Scientists at the Department of Energy’s Fermi National Accelerator Laboratory and the University of Chicago have demonstrated a new technique based on quantum technology that will advance the search for dark matter, the invisible stuff that accounts for 85% of all matter in the universe.
