Electro-optic modulated Franson interferometer for deterministic photon routing. a Energy basis regime to maximise counts flowing into the interfering state and confirm channel security. b Time basis regime to deterministically split qubits in time and use them as source of secure quantum information. Example two dimensional histograms and state representation in the Bloch sphere are reported on the side panels for the two cases.
