Summary
University College Dublin researchers and collaborators published a practical guide in PRX Quantum showing how critical quantum sensing can be built on existing experimental platforms.
The method exploits quantum phase transitions—tipping points where tiny changes in temperature, pressure or magnetic fields trigger large responses—to amplify weak signals beyond classical sensing limits.
Near those critical points, the team says sensors can gain precision while staying more resilient, because collective system behavior can blunt some environmental noise that usually disrupts quantum devices.
The guide also maps implementation challenges, including keeping systems tuned close to instability without losing control, as researchers push toward real-world uses in navigation, medical imaging and experiments such as LIGO.
