摘要

对于由一般量子稳定器代码构建的量子秘密共享方案，除了Cleve， Gottesman和Lo提出的特定类别外，没有已知的无测量电路可以重建其量子秘密。提出了一种基于稳定码的量子秘密共享中量子秘密的无测量重构电路。我们的重构电路宽度为\(k+|J|\)，当|J|参与者重构k-qudit量子秘密时，重构电路由O（k|J|）一个或两个qudit酉门组成。

Measurement-free reconstruction circuit of quantum secrets in quantum secret sharing

For a quantum secret sharing scheme built from a general quantum stabilizer code, no measurement-free circuit has been known for reconstructing its quantum secrets, except particular classes, such as one proposed by Cleve, Gottesman and Lo. We propose a measurement-free reconstruction circuit of quantum secrets in quantum secret sharing based on stabilizer codes. Our reconstruction circuit has width \(k+|J|\) and consists of O(k|J|) one- or two-qudit unitary gates when |J| participants reconstruct k-qudit quantum secrets.
