Daniele Cozzolino, Emanuele Polino, Mauro Valeri, Gonzalo Carvacho, Davide Bacco, Nicoló Spagnolo, Leif Katsuo Oxenløwe and Fabio Sciarrino Distribution of photonic entangled states using optical fiber links is fundamental for quantum networks. The orbital angular momentum (OAM) is one of the most promising degree of freedom due to its capability to encode high-dimensional states. We demonstrate fiber distribution of hybrid polarization-vector vortex entangled photon pairs by exploiting an air-core fiber which supports OAM modes. Distribution of the entangled states is demonstrated by performing quantum state tomographies, by violations of Bell inequalities and multipartite entanglement tests. The present results open new scenarios for quantum applications where correlated complex states can be transmitted by exploiting the vectorial nature of light.
