Abstract：Multi-particle cluster states,which have received much attention recently for their maximum connectivity,persistent entanglement and robustness to decoherence.How to prepare multi-particle cluster states has become one of the hot issues in the field of quantum information.This work introduces superadiabatic shortcut scheme for quantum phase gates and prepare 4-particle cluster states.The traditional adiabatic channel scheme requires two steps,and may be ineffective due to the long evolution time of the system.The scheme in this work takes only one step,which greatly reduces the difficulty of experimental realization and various losses in the experimental process.Numerical simulations show that the superadiabatic shortcut scheme is robust to the decoherence effects caused by spontaneous atomic emission and cavity decay in the cavity system,and takes less time than the traditional adiabatic channel scheme.
