We tune the single photon source and filters to heralded the presence of photons at $λ_s$ into the BS setup. The heralding rate is about 200 KHz for a detected pair rate of ~6000 #/s. Pumps can indeed be triggered to be generated on the event of a heralded photons, but the conversion efficiency is technically limited by the amplitude fluctuations introduced by the EDFA due to the random time between pulse generation. In this condition, the best conversion obtained is ??.  To overcome this limitation, we let the system run independently in condition similar to the classical measurement, and we record the three-fold coincidences between signal, herald and pump: in this condition the detected pair rate is ~20 pairs/s in a 0.8-nanosecond window. We show the results figure ?, where we observe a conversion efficiency of ?.  Unitary conversion efficiency is limited by the fact that single photon bandwidth ( δλ =0.57 $\delta \lambda =0.57$  nm FWHM) and the acceptance ( δλBS $\delta \lambda_{BS}  = 1.17(2) 1.17(2)$  nm FWHM) are comparable: theoretical calculation show a maximum efficiency $\eta$ of about $89%$.
