... photon state ( Fig . 2b ) . We now explain how our scheme can be generalized to four ( 1 ) photons and even higher photon numbers . Consider the case where four photons are emitted on a double pass of the pump beam through the crystal ...

... photons in a single pulse , so we can infer with near - certainty the absence of photons in the ' dark ' port from the presence of both photons in the ' bright ' port . Using a weak coherent state to supply the third photon , we can ...
