Abstract

During the past decade, quantum optics development has been an interesting platform option for experimental implementation of quantum information and fundamental quantum mechanic tests. Implementation using single photons, using heralded or entangled source, have versatility to be manipulated on free space, fiber optics or photonic chips. The encoding can be done in different degrees of freedom of a photon, e.g., path, transversal and polarization. In photonic chips all three cited encoding an be manipulated and used together to build a higher dimension system to implement quantum information protocols using qudits (d-level quantum system).
