Photonic quantum information processing in metropolitan networks lays the foundation for cloud computing [1, 2], secure communication [3, 4], and realization of a global internet [5, 6]. This paradigm shift requires on-demand high-rate generation flying qubits their state teleportation over long distances [7]. Despite last decade has witnessed an impressive progress performances deterministic photon sources [8-11], exploitation distinct emitters to implement all-photonic among distant...
We report on an experiment in which orbital-angular-momentum (OAM)-entangled photon pairs generated by the spontaneous parametric down-conversion process can be engineered to have particular symmetry properties. Our method is based use of a Dove-prism pair conjunction with Hong-Ou-Mandel (HOM) interferometry resolved transverse position and OAM. The latter allows us engineer postselected two-photon state exhibit specific type symmetry. By selecting topological charge values for pump state,...
