Researchers develop new quantum sensor for dark matter detection
A team of scientists has unveiled a novel quantum sensor that could revolutionize the search for dark matter. The device, detailed in a recent study, uses advanced quantum technology to detect elusive particles with unprecedented sensitivity. This breakthrough promises to advance our understanding of the universe's hidden components.
In a study published on September 30, 2025, researchers from the University of California, Berkeley, announced the development of a quantum sensor designed specifically for detecting dark matter particles. Dark matter, which is estimated to make up about 85% of the universe's mass, has long eluded direct detection despite numerous experiments.
The sensor employs nitrogen-vacancy centers in diamond to measure subtle changes in magnetic fields potentially caused by weakly interacting massive particles (WIMPs), a leading dark matter candidate. Lead researcher Dr. Elena Rossi explained, 'This quantum approach allows us to probe signals that traditional detectors might miss, offering a sensitivity boost of up to 100 times.' The technology builds on quantum sensing principles first explored in the early 2010s, with prototypes tested in laboratory conditions from 2023 to 2025.
The team's experiments involved cooling the sensor to near-absolute zero temperatures and exposing it to simulated dark matter interactions. Results showed the device could distinguish potential dark matter signals from background noise with high precision. 'We've crossed a critical threshold in sensitivity,' Rossi added, emphasizing the sensor's potential for integration into larger underground detectors like those at the Sanford Underground Research Facility.
This development comes amid ongoing challenges in particle physics, where previous searches, such as those by the LUX-ZEPLIN experiment, have yielded null results. The new sensor addresses some limitations by operating at room temperature for certain components, reducing operational costs. Implications include not only dark matter hunts but also applications in medical imaging and navigation systems.
While the study marks progress, the researchers caution that field deployment and real-world validation are needed. The findings were published in the journal Nature, peer-reviewed by experts in quantum physics and astrophysics.
