    "abstract": "Multiphoton entanglement is an important resource for linear optics quantum\ncomputing. Here we show that a wide range of highly entangled multiphoton\nstates, including W-states, can be prepared by interfering single photons\ninside a Bell multiport beam splitter and using postselection. A successful\nstate preparation is indicated by the collection of one photon per output port.\nAn advantage of the Bell multiport beam splitter is that it redirects the\nphotons without changing their inner degrees of freedom. The described setup\ncan therefore be used to generate polarisation, time-bin and frequency\nmultiphoton entanglement, even when using only a single photon source.",
