论文摘要
这项工作提出了一种基于GHz产品状态共享的新型量子秘密共享策略。经销商根据要共享的经典信息，可以切换他的量子并共享产品状态。其他各方进行了钟声测量，并勾结以重建秘密。与其他协议不同，该协议不涉及整个初始状态重建，而是使用选择性量子位在重建时丢弃冗余量子，以解密秘密。该协议还允许对手的恶意攻击安全，而不会影响秘密的完整性。协议的安全性在于，各方正确公布其测量需要进行重建，而失败的重建过程会危及重建过程，从而确定$（3,3）$方案可以进一步扩展到$（n，n）$方案。
The work presents a novel quantum secret sharing strategy based on GHZ product state sharing between three parties. The dealer, based on the classical information to be shared, toggles his qubit and shares the product state. The other parties make their Bell measurements and collude to reconstruct the secret. Unlike the other protocols, this protocol does not involve the entire initial state reconstruction, rather uses selective qubits to discard the redundant qubits at the time of reconstruction to decrypt the secret. The protocol also allows for security against malicious attacks by an adversary without affecting the integrity of the secret. The security of the protocol lies in the fact that each party's correct announcement of their measurement is required for reconstruction, failing which the reconstruction process is jeopardized, thereby ascertaining the $(3,3)$ scheme which can further be extended for a $(n,n)$ scheme.
