使用多方态的量子密钥共享方案(英文)

Quantum secret sharing scheme by multipartite state

给出使用Sen等推广的多方对称态的量子密钥共享方案,我们采用不同的方法证明这个方案是安全的.然后,根据局域实在性的破缺,证明了对称的多方量子态的量子密钥共享的安全性,并作了进一步的推广.

We present a quantum secret sharing scheme（QSS） using multipartite symmetric state generalized from Sen.We prove this scheme is secure using a different method.Then we show the security of secret sharing in terms of violation of local realism still works for symmetric multipartite state.At the same time,we provide futher generalization.
