An efficient quantum secret sharing scheme with Einstein-Podolsky-Rosen   Pairs
  An efficient quantum secret sharing scheme is proposed. In this scheme, the particles in an entangled pair group form two particle sequences. One sequence is sent to Bob and the other is sent to Charlie after rearranging the particle orders. Bob and Charlie make coding unitary operations and send the particles back. Alice makes Bell-basis measurement to read their coding operations.
