Single molecule techniques improve our understanding of the photon and light. If the single photon double slit experiment is performed at the single photon limit of a multi-atom light source, faint light pulses with more than one photon hamper the interpretation. Single molecules, quantum dots or defect centres in crystals should be used as light source. Single photon detectors do not meet their promise-only photon number resolving single photon detectors do so. Particularly, the accumulation time argument, the only safe basis for the postulate of a strictly particle like photon, has so far not yet been verified.
