Until now, pinpointing exceptional points in quantum systems offered no guarantee signals weren’t lost or simply unobserved by detectors. This work delivers the first method definitively establishing whether observed responses reflect actual behaviour at these sensitive junctures, or limitations within experimental apparatus. Using a red-sideband optomechanical system, scientists can now certify access to two or three dynamic directions with quantifiable error bounds.
