| Jan 5 at 2:50 | comment | added | PhysicsDave | Photon shot noise is the noise in light itself. For single photons this noise shows itself as statistical noise in the emission rate ….. i.e. if you energize the source at time t the photon will appear at some time t +/- sigma. | |

| Jan 4 at 17:46 | comment | added | A. P. | I recently answered a similar question: "What does $\tau$ mean in second-order correlation function?" The asker there was learning from a tutorial by qutools, which I can recommend. For characterizing single-photon sources, see Ch. 2.2 therein. | |

| Jan 4 at 17:32 | comment | added | Ang | @A.P. Thanks for your question. I'm asking if a single-photon detector/apparatus exists that provides information about each single emission event from the source. The information should be "I got a single-photon" or "I got more than 1 photon". | |
| Jan 4 at 17:21 | comment | added | A. P. | Since usually a large number of photons is used for the excitation, the established procedure verifies the single-photon character by inspecting the emission of the source instead of its effect on the excitation pulse. Is there any constraint in your specific experiment which makes you prefer investigating how much light is absorbed? | |
