We show a simulation of quantum random walks (QRWs) with multiple photons using staggered array 50/50 beam splitters bank detectors at any desired level. discuss the multiphoton interference effects that are inherent to this setup, and introduce one, two, threefold coincidence detection schemes. Feynman diagrams used intuitively explain unique these QRWs.
