Despite being very inuential on both foundations and applications of quantum mechanics, weak values arestill somewhat controversial. Although there are some indications that weak values are physical properties ofa single quantum system, the common way weak values are presented is statistical: it is commonly believedthat for measuring weak values one has to perform many weak measurements over a large ensemble of pre- andpostselected particles. Other debates surround the anomalous nature of weak value and even their quantumness.To address these issues, we present some preliminary data showing that anomalous weak values can be measuredusing just a single detection, i.e. with no statistics. In our experiment, a single click of a detector indicatesthe weak value as a single photon property, which moreover lies well beyond the range of eigenvelues of themeasured operator. Importantly, the uncertainty with which the weak values is measured is smaller than thedi erence between the weak value and the closet eigenvalue. This is the rst experimental realization of robustweak measurements.
