Quantum interference induced by hyper-entanglement in energy-time and discrete-frequency.

(a) The interference fringes of the net coincidence counts in the experiment of Franson-type interference. The interference visibilities are 98 ± 1% (β = 6.38 rad) and 99 ± 1% (β = 7.29 rad), respectively. (b) The spatial quantum beating fringe of the net coincidence counts induced by the frequency entanglement. The visibility of the spatial quantum beating fringe is 91 ± 3%.
