Towards Robust Optimal Measurements Against Noise in Quantum Metrology Measurements previously assessed for precision are now demonstrably ranked by their susceptibility to noise, revealing which schemes falter most under real-world conditions. Experiments utilising a polarizing Mach-Zehnder interferometer confirm that Fisher information measurement noise susceptibility (FI MENOS) defines the absolute limit of estimation precision. This work offers a new means of evaluating how well quantum m...
