Conceptual scheme of the proposed protocol.

Caption

Conceptual scheme of the proposed protocol. Manipulating the polarization and OAM of single photons generated from a QD source in a nearly deterministic fashion, intraparticle entangled states are generated by making the two degrees of freedom interact through a q-plate. In the interparticle regime, two photons characterized by specific states in the hybrid space composed of polarization and OAM interfere using a beam-splitter. Post-selecting on the coincidence counts, a probabilistic entangling gate has been implemented.
