A first attempt to investigate nonlocality over large distances was reported in
-
A first attempt to investigate nonlocality over large distances was reported in 6. However, it contrasts with ours, as both analyzers were positioned next to the source, one connected with a 4.3 km fiber on a spool, while the other analyzer was directly connected to the source. Therefore, the physical distance between the two analyzers was of only a few meters.

We would like to mention that postselecting only events leading to the central coincidence peak in order to create the entangled state [Eq. (3)] constitutes a fundamental loophole in these kinds of Bell-type tests

To avoid this inconvenience, one could use type-II phase matching and exploit the fact that, in this case, signal and idler photons are orthogonally polarized in order to separate all pairs

There might be an interesting effect caused by the interplay of chromatic-dispersion-caused coincidence peak broadening and a coincidence window that selects only a subensemble of the whole peak. To simplify the argument, we neglect the intrinsic detector time jitter for a moment. Then, maximal or minimal values in the coincidence-detection time spectrum can be caused only by wave trains lying at the upper or lower end of the photon spectrum. The effect of a small coincidence window is then somehow similar to the use of a spectral filter. However, since the detection time jitter is dominant in our case, this filtering should be very small

The coincidence window has been set to a small value in order to achieve a better ratio of detected to accidental coincidences (Formula presented). However, a violation of Bell inequalities could have been achieved with a three-times-larger window as well. Due to a lower (Formula presented), the raw visibility of the coincidence fringes would drop from (Formula presented) to around (Formula presented) and still violate Eq. (10)

Unequal path-length differences in both interferometers (Formula presented) increase the possibility of differentiating between the long-long and short-short paths (by looking at the differences in photon arrival time), hence decreasing the visibility
