11. Due to the different velocity of the light inside the crystals for ordinary and extraordinary propagation, narrow frequency bandwidth filters F and compensating crystals 7 can be used to produce the time superposition of the single-photon wave packets in coincidence counts. See the work of Kwiat et al. in Ref. 8. “Quasi-phase-matched” crystals eliminate the need of compensating crystals.
12. A tetrat set of wave functions providing only orthogonal singly polarized states can also be easily created with this same emitter and identified with a simple coincidence detection system, without need of the HOM interferometer. In this simpler experimental scheme, the code density for all elements is the classical one, (Formula presented) and again it cannot be made by a classical source.
