Photon number conservation and photon interference

Mátyás Koniorczyk, József Janszky

Research output: Contribution to journalConference article


The group theoretical aspect of the description of passive lossless optical four-ports (beam splitters) is revisited. It is shown through an example, that this approach can be useful in understanding interferometric schemes where a low number of photons interfere. The formalism is extended to passive lossless optical six-ports, their SU(3)-theory is outlined.
