Interference of photons emerging from independent sources is essential for modern quantuminformation 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)%.
