Entanglement and the wave function description are two of core concepts that make quantum mechanics such a unique theory. A method to directly measure function, using weak values, was demonstrated by Lundeen et al. [Nature 474, 188 (2011)]. However, it is not applicable scenario disjoint systems, where nonlocal entanglement can be crucial element, since requires obtaining values observables. Here, for first time, we propose bipartite system, modular values. The experimentally implemented...

We report the experimental measurement of winding number in an unitary chiral quantum walk. Fundamentally, spin-orbit coupling discrete time walks is implemented via birefringent crystal collinearly cut based on time-multiplexing scheme.
