  Preparation of entangled states of photons are useful for quantum computing
and communication. In this paper, we present a simplistic protocol of
entanglement generation using beam splitters with suitable reflectivity. The
photons in an initial state with fully classical probability distribution pass
through an optical network, made up of sequential beam splitters and are
prepared in maximally entangled states. We also present the detailed
theoretical analysis of entangled state generation, for an arbitrary number of
photons, fed through the input ports of the beam splitters with equal
probability.
