Robust Weak Measurements with Certified Single Photons (Adv. Quantum Technol. 7/2025)
Robust weak measurements are an experimental protocol able to reliably obtain (anomalous) weak values with single quantum systems even without averaging over multiple experimental runs. The picture shows an optical implementation able to extract the polarization weak value of heralded single photons, certifying the true single-particle, nonclassical nature of weak values.
