Whichever way information is physically represented in the real world, it is subject to the laws of quantum theory and relativity. In the case of traditional physical representations of information, such as letters on paper, the laws of classical physics suffice, of course, for a good description. Research over the past few years has shown, however, that there are dramatic new effects when information is represented or processed on the subatomic level and/or in the presence of strong gravity. Then, the laws of quantum theory, such as the uncertainty principle and entanglement, and the laws of relativity, such as the finite maximum speed of communication and unpenetrable horizons, yield a very profound impact on the way that information can be represented and processed, both in principle and in practice.

无论信息在真实的世界中以何种物理方式表现，它都要服从量子理论和相对论的定律。在传统的信息物理表示的情况下，例如纸上的信件，经典物理定律当然足以进行良好的描述。然而，过去几年的研究表明，当信息在亚原子水平上和/或在强引力存在的情况下表示或处理时，会产生引人注目的新效果。然后，量子理论的定律，如不确定性原理和纠缠，以及相对论的定律，如有限的最大通信速度和不可穿透的视界，对信息的表示和处理方式产生了非常深远的影响，无论是在原则上还是在实践中。
