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