我们探讨了量子秘密共享（QSS）的推广，其中经典共享对量子共享起补充作用，探索了Nascimento，Mueller-Quade和Imai [Phys. Rev. A 64，042311（2001）]首次研究的想法的进一步后果。我们研究了三种方法，称为通货膨胀，压缩，和双阈值，古典股票的比例可以增加。这有一个重要的应用，它减少了量子（信息处理）的球员，取代他们与他们的经典同行，从而使量子秘密共享相当容易和更便宜的实现在一个实际的设置。在压缩中，QSS方案变成具有较少量子参与者的等效方案，并通过适当的经典份额进行补偿。在通货膨胀中，QSS方案通过仅添加经典股票和参与者来扩大。在一个双阈值方案中，我们调用两个单独的阈值经典和量子份额的基础上的信息稀释的想法。
We explore a generalization of quantum secret sharing (QSS) in which classical shares play a complementary role to quantum shares, exploring further consequences of an idea first studied by Nascimento, Mueller-Quade, and Imai [Phys. Rev. A 64, 042311 (2001)]. We examine three ways, termed inflation, compression, and twin thresholding, by which the proportion of classical shares can be augmented. This has the important application that it reduces quantum (information processing) players by replacing them with their classical counterparts, thereby making quantum secret sharing considerably easier and less expensive to implement in a practical setting. In compression, a QSS scheme is turned into an equivalent scheme with fewer quantum players, compensated for by suitable classical shares. In inflation, a QSS scheme is enlarged by adding only classical shares and players. In a twin-threshold scheme, we invoke two separate thresholds for classical and quantum shares based on the idea of information dilution.
