Researchers Boost Sensor Accuracy by Fifteen Per Cent

Until now, discerning information from quantum sensors required multiple measurements followed by classical computer analysis to refine signal estimates. Researchers at Cornell University and Massachusetts Institute of Technology have demonstrated quantum computational sensing, a new approach that integrates computation directly into the measurement process using a single superconducting qubit. This innovation concentrates relevant data within each individual measurement; for static magnetic field tasks, their protocol achieved up to fifteen percentage points better performance than existing methods. Researchers have developed a new form of quantum sensing…
