Centre National De La Recherche Scientifique (2007, April 2). Life And Death Of A Photon 'Filmed' For The First Time. ScienceDaily. Retrieved March 22, 2008Arkiveret 20. april 2008 hos Wayback Machine Citat: "...A photon is an elementary particle of light. In general it can only be observed when it disappears...The end result is that the atom changes to state 1 if the cavity contains a photon and remains at state 0 if it is empty, as in the standard method. However, this time the energy absorbed by the atom is taken from the auxiliary field and not from that of the cavity. As a result, the photon is still there after having been seen, and is ready to be measured again...Suddenly the atoms appear in state 1, showing that a photon has been trapped between the mirrors. The photon comes from the residual thermal radiation which surrounds the cavity..The moments at which the photons appear and disappear reveal the quantum jumps of light, which occur at random..."
