In this area, Argonne is exploiting a variety of quantum mechanical features — such as quantized energy levels, quantum state squeezing, superposition, interference, and entanglement — to perform highly sensitive measurements, sometimes in ways that can effectively evade the Heisenberg uncertainty principle.

Argonne’s projects in this area include developing superconducting detectors for particle and nuclear physics applications, quantum-enhanced metrology for dark matter detection, and the sensing of magnetic fields with quantum defect qubits.
