Photonic path states produced when photon pairs generated by parametric downconversion cross double or multiple slits allowed us to study the generation of high dimension qudits states, measurement of its photonic path state entanglement and its characterization. We show in this talk two more recent quantum information experiments where photon pairs in path states and a spatial light modulator are employed for doing tomography in their state and for demonstrating the Deutsch algorithm with one path state qubit.
