Scientists Develop Ultra-Sensitive Quantum Detectors to Hunt Dark Matter

New experiments using supercold quantum technology aim to directly detect elusive particles that make up most of the universe's mass.

Two experiments, QUEST-DMC and QSHS, are being conducted by UK universities to detect different hypothetical dark matter particles.
QUEST-DMC uses superfluid helium-3 to search for weakly interacting new particles with masses between 0.01 to a few hydrogen atoms.
QSHS focuses on detecting axions, extremely light particles, by measuring tiny electrical signals from their decay in a magnetic field.
Both experiments require chilling equipment to a thousandth of a degree above absolute zero to prevent interference in measurements.
The public can view these experiments and learn about dark matter detection at Lancaster University's Summer Science Exhibition.
