Anomalous weak values via a single photon detection

摘要

The vertical solid lines show the borders and centre of the eigenvalue spectrum of our observable, while the dashed line indicates its weak value calculated according to the experimental parameters, i.e., (σ3Σ)w=18.7. The experimental point, shown in white, gives the value (σ3Σ)w1click=21.4. The uncertainty, represented by the horizontal green bars, is specified by calculating the width of the spatial wave function of the quantum particle before the detection, and confirmed by repeating the experiment many times
