摘要

Measurement-based quantum computation in an optical setup shows great promise towards the implementation of large-scale quantum computation.The difficulty of measurement-based quantum computation lies in the preparation of cluster state.In this paper,we propose the method of generating the large-scale cluster state,which is a platform for measurement-based quantum computation.In order to achieve more complex quantum circuits,the preparation protocol of N-photon cluster state will be proposed as a generalization of the preparation of four-and five-photon cluster states.Furthermore,our proposal is experimentally feasible.
