摘要
一(n， n ) 多党的量秘密分享的阀值计划古典或量消息基于分离的量 Fourier 变换被建议。在我们的建议计划，仅当所有参加者在音乐会工作，秘密消息，被使用前面的量 Fourier 变换编码并且由使用颠倒译码，以如此的一个方法被切开并且分享，它能在他们之中被重建。而且，我们也讨论这个协议怎么必须小心地为改正错误或一个不诚实的参加者被设计。安全分析证明我们的计划是安全的。另外，这个计划有它与量计算完全兼容的一个优点并且更容易在分布式的量认识到安全计算。
A （n, n）-threshold scheme of multiparty quantum secret sharing of classical or quantum message is proposed based on the discrete quantum Fourier transform. In our proposed scheme, the secret message, which is encoded by using the forward quantum Fourier transform and decoded by using the reverse, is split and shared in such a way that it can be reconstructed among them only if all the participants work in concert. Fhrthermore, we also discuss how this protocol must be carefully designed for correcting errors and checking eavesdropping or a dishonest participant. Security analysis shows that our scheme is secure. Also, this scheme has an advantage that it is completely compatible with quantum computation and easier to realize in the distributed quantum secure computation.
