| 摘 要： | 利用GHZ态作为量子信道，再辅以经典信道传送经GHZ态测量后的信息，便可实现量子位的秘密共享．基于上述思想，充分利用六粒子GHZ纠缠态的相关性，通过1次Bell基测量、4次单粒子测量和相应的幺正变换，从而实现了4个量子位的秘密共享方案.

| Abstract: | With GHZ state as a quantum channel,quantum bit secret sharing can be realized after transmitting the information by a classical channel,which is measured by the GHZ state.Based on the above ideas,making full use of the correlation of a six-particle entanglement GHZ state,by a Bell measurement,four single-particle measurements and the corresponding unitary transformation,a four-qubit secret sharing scheme can be achieved. |
