Franson-type interference induced by the energy-time entanglement.

(a) A typical result of the coincidence in the experiment of Franson-type interference. The square with dashed line indicates the time domain filter used to extract the coincidence counts. (b) The interference fringes of the net coincidence counts in the experiment of Franson-type interference. The visibilities are 99 ± 1% (β = 6.38 rad), 99 ± 1% (β = 7.29 rad), calculated by curve fitting.
