    "abstract": "We theoretically demonstrate a method for producing the maximally\npath-entangled state (1/Sqrt[2]) (|N,0\u003e + exp[iN phi] |0,N\u003e) using\nintensity-symmetric multiport beamsplitters, single photon inputs, and either\nphoton-counting postselection or conditional measurement. The use of\npostselection enables successful implementation with non-unit efficiency\ndetectors. We also demonstrate how to make the same state more conveniently by\nreplacing one of the single photon inputs by a coherent state.",
