  "abstract": "Weak values are traditionally obtained using a weak interaction between the measured system and a pointer state. In this paper, we show that weak values can also be measured using strong interaction accompanied by either a suitably prepared pointer state or quantum erasure. Presented theoretical derivations prove analytical equivalence of these approaches. Moreover, we have performed an experimental verification of our model on a linear-optical controlled phase gate. Our results open new ways of performing non-invasive quantum measurements without collapsing the measured system.",
