Abstract

We show a simulation of quantum random walks with multiple photons using a\nstaggered array of 50/50 beam splitters with a bank of detectors at any desired\nlevel. We discuss the multiphoton interference effects that are inherent to\nthis setup, and introduce one, two, and threefold coincidence detection\nschemes. The use of Feynman diagrams are used to intuitively explain the unique\nmultiphoton interference effects of these quantum random walks.\n
