Popis:	We prepare single photons with a temporal envelope with rising exponential shape, resembling the time-reversed version of photons from the spontaneous decay process using a parametric conversion process in a cold atomic vapor. The mechanism is based on correlated photon pair preparation and heralding of one photon by the other one after engineering the temporal envelope of the herald.1 Such a temporal single photon profile is ideal for absorption by a two level system.2, 3 We demonstrate this in an experiment showcasing the absorption by a single Rubidium atom.4
