Quantum sharing of classical secret based on local operations

We show a quantum sharing of classical secret protocol using EPR pairs. Instead of distributing entangled particles to every player and letting them make a measurement in different bases randomly, we employ the entangled particles as a carrier to record the synthetical operations of all players. Even in the case of multi-party secret sharing, two-particle entanglement is enough. Furthermore, the present scheme can achieve nearly 100% efficiency in principle
