Quantum secret sharing of an arbitrary two-particle entangled state via non-maximally entangled channels

In this paper, a quantum secret sharing scheme is proposed for an arbitrary two-particle entangled state among N agents. The scheme adopts the non-maximally entangled Bell states as quantum channels and the generalized Bell states as the measurement basis. By introducing an auxiliary particle and making selective measurement on it, the receiver can obtain the original quantum state with a probability less than unity.
