The existing secret sharing schemes of sharing quantum information usually require the resource of entanglements no matter they are based on quantum teleportation or remote state preparation. However, in the practical applications, it is difficult to build faithful and stable entangled channels among many users. We show how the quantum information splitting and reconstruction can be implemented without the assistance of entanglements and give a quantum secret sharing protocol based on the theory of quantum interference. We also discuss its security against the individual attacks and generalize its three-party case into a multiparty case.
