量子秘密共享方案与量子操作的可逆性

Quantum Secret Sharing Schemes and Reversibility of Quantum Operations

Tomohiro Ogawa, Akira Sasaki, Mitsugu Iwamoto, Hirosuke Yamamoto

摘要:

讨论了将量子态加密为多体纠缠态的量子秘密共享方案。基于量子操作的可逆性与Holevo信息之间的关系,重新讨论了Gottesman [Phys.Rev.A \textbf{61},042311(2000)]给出的每个份额的维数下限。我们还提出了一个门限斜坡量子秘密共享方案,并评估其编码效率。

英文摘要:

Quantum secret sharing schemes encrypting a quantum state into a multipartite entangled state are treated. The lower bound on the dimension of each share given by Gottesman [Phys. Rev. A \textbf{61}, 042311 (2000)] is revisited based on a relation between the reversibility of quantum operations and the Holevo information. We also propose a threshold ramp quantum secret sharing scheme and evaluate its coding efficiency.
