Quantum techniques boost dark matter detection sensitivity significantly

phys.org — August 1, 2024, 01:00 PM UTC

Summary: Researchers at Fermi National Accelerator Laboratory and the University of Chicago enhanced dark matter detection by 2.78 times using quantum techniques. By preparing a microwave cavity in a special quantum state and employing superconducting qubits, they increased measurement sensitivity while reducing noise. This method allows for better detection of weak dark matter signals, potentially accelerating discoveries in fundamental physics. The findings were published in *Physical Review Letters*.
