@article{Kaltenbaek2006ExperimentalIO, title={Experimental interference of independent photons.}, author={R. Kaltenbaek and B. Blauensteiner and M. Zukowski and M. Aspelmeyer and A. Zeilinger}, journal={Physical review letters}, year={2006}, volume={96 24}, pages={ 240502 } }

Interference of photons emerging from independent sources is essential for modern quantum-information processing schemes, above all quantum repeaters and linear-optics quantum computers. We report an observation of nonclassical interference of two single photons originating from two independent, separated sources, which were actively synchronized with a rms timing jitter of 260 fs. The resulting (two-photon) interference visibility was (83+/-4)%.
