Abstract
Using energy correlated photon pairs created in parametric down-conver sion we demonstrate two-photon interference effects in fiber interfero meters separated by 4.3 km of optical fiber. The measured 86% interfer ence visibilities confirm the purely quantum mechanical origin of thes e correlations.
