论文摘要
量子信息掩蔽是一种协议，它隐藏了子系统中的原始量子信息并将其扩展到量子相关性上，该量子相关性可用于除两部分系统以外的多部分。在这项工作中，我们明确研究了多部分场景中的量子信息掩蔽，并证明所有K级量子状态都可以掩盖到MQUDIT系统（M> 4）中，其局部尺寸d <k和k的上限比量子单元键更紧。为了直观地观察掩盖过程，提供了明确控制的操作。我们的方案很好地证明了多方量子系统之间的量子相关性，并且在量子信息处理的安全性中具有潜在的应用。
Quantum information masking is a protocol that hides the original quantum information from subsystems and spreads it over quantum correlation, which is available to multipartite except bipartite systems. In this work, we explicitly study the quantum information masking in multipartite scenario and prove that all the k-level quantum states can be masked into a m-qudit systems (m > 4) whose local dimension d < k and the upper bound of k is tighter than the quantum Singleton bound. In order to observe the masking process intuitively, explicitly controlled operations are provided. Our scheme well demonstrates the abundance of quantum correlation between multipartite quantum system and has potential application in the security of quantum information processing.
