在量子理论中，信息的概念与经典物理学中的对应概念没有什么不同：不需要一个特殊的量子信息概念。然而，量子世界与其经典世界截然不同。物质世界的这种结构差异对物理系统中可以存储的信息量和信息传输的可能性产生了重要的影响。在许多情况下，量子态之间的重叠(态的非正交性)模糊了区别，阻碍了有效的信息传输。然而，另一个典型的量子特征--纠缠--使新的、看似神秘的信息传输方式成为可能。在这篇文章中，我们提出了一种从透视性物理性质的角度来解释量子力学的方案，它可以对这些新的量子可能性提供一个可理解的解释，同时保持接近量子力学的数学形式主义。
The concept of information is not different in quantum theory from its counterpart in classical physics: a sui generis quantum information concept is not needed. However, the quantum world is radically different from its classical counterpart. This difference in structure of the material world has important consequences for the amounts of information that can be stored in physical systems and for the possibilities of information transfer. In many cases, overlap between quantum states (non-orthogonality of states) blurs distinctions and impedes efficient information transfer. However, the other typical quantum feature, entanglement, makes new and seemingly mysterious ways of transporting information possible. In this article, we suggest an interpretational scheme of quantum mechanics in terms of perspectival physical properties that may provide an intelligible account of these novel quantum possibilities, while staying close to the mathematical formalism of quantum mechanics.
