Experimental investigation of the connection between weak measurements and violation of the Leggett-Garg Inequality

ORAL

Abstract

By weakly measuring the polarization of a photon between two strong polarization measurements, we experimentally demonstrate that there is a one-to-one correlation between achieving strange weak values and violating the Leggett-Garg inequality (LGI) as was recently predicted by Williams and Jordan [N. S. Williams, and A. N. Jordan {\bf 100}, 026804 (2008)]. Furthermore, we investigate the effect of measurement strength on the magnitude of the anomalous weak values and the extent of the LGI violation.
