A framework of quantum secret sharing (QSS) is proposed on the basis of the Chinese Remainder Theorem (CRT) with nonmaximally entanglement qubit pairs.In the present scheme,the secret is divided and allotted to two or more participants with respect to shadows achieved from the CRT.The secret can be restored jointly by all legal participants via the nonmaximally entanglement analysis.The security is guaranteed from the entanglement of the photons prepared beforehand.It provides an altemative technique for the QSS while producing the the multi-photon entanglement sates in the multi-dimensional Hibert space,where the CRT is conducted properly for the secret sharing among multi-participants.
