In this thesis, the quantum interference of two single photons with individually tunable wavelength is studied. The photons are generated one-after-the-other using an adiabatic passage in an atom-cavity system. They travel through two different optical fibers and impinge simultaneously on a beam splitter. The photon duration is much longer than the time resolution of the detectors placed at the two output ports of the beam splitter, therefore the coincidence of photodetections can be studied as a function of the time between two detections. Simultaneous detections are never observed, even in the case that the photons are distinguishable in frequency, or have a bad overlap in time. If the interfering photons have a frequency difference, the coincidence probability oscillates as a function of the time between the detections. This oscillation shows a visibility of nearly 100 %, which results from the quantum nature of light and cannot be explained classically.
