Query: Single-photon stimulated four wave mixing at telecom band   Single-photon stimulated four wave mixing (StFWM) processes have great
potential for photonic quantum information processing, compatible with optical
communication technologies and integrated optoelectronics. In this paper, we
demonstrate single-photon StFWM process in a piece of optical fiber, with
seeded photons generated by spontaneous four wave mixing process (SpFWM). The
effect of the single-photon StFWM is confirmed by time-resolved four-photon
coincidence measurement and variation of four-photon coincidence counts under
different seed-pump delays. According to the experiment results, the potential
performance of quantum cloning machine based on the process is analyzed.
