| Abstract: | Based on entanglement swapping, a scheme for the secret sharing of an arbitrarytwo-particle entangled state is proposed. If the controllers do not co-operatewith the eavesdropper, the eavesdropper's successful probability decreases with thenumber of the controllers increasing. In addition,only the Bell-state measurements arerequired to realize the secret sharing scheme. |
