Abstract

Multipartite concatenated Greenberger–Horne–Zeilinger (C-GHZ) states, a class of multipartite entangled states, have superior stability under the influence of decoherence. We propose two means of constructing multiphoton C-GHZ states based on entanglers of multiphoton GHZ states that are both experimentally realizable and scalable. Given a km-photon GHZ state as an input state, if m is odd, one can create a km-photon C-GHZ state. In addition, we have designed a scheme to prepare km-photon C-GHZ states from km single-photon states by using k entanglers of m-photon GHZ states and k m-control Toffoli gates.
