黑洞与信息论
Black holes and information theory
摘要:
在过去的30年里,研究人员已经揭示了物理信息和黑洞之间的许多深层联系,这些联系对普通系统的影响超出了纯粹从信息论公理推导出来的结果。在对黑洞热力学进行了完整的介绍之后,我们从它的有利位置回顾了一些主题,如从初始黑洞辐射能力中出现的信息难题,非黑洞系统的各种熵界(全息熵界、普适熵界等),Bousso协变熵界,粒子物理的全息原理,量子通信信道的信道容量等课题。
英文摘要:
During the past three decades investigators have unveiled a number of deep connections between physical information and black holes whose consequences for ordinary systems go beyond what has been deduced purely from the axioms of information theory. After a self-contained introduction to black hole thermodynamics, we review from its vantage point topics such as the information conundrum that emerges from the ability of incipient black holes to radiate, the various entropy bounds for non-black hole systems (holographic bound, universal entropy bound, etc) which are most easily derived from black hole thermodynamics, Bousso's covariant entropy bound, the holographic principle of particle physics, and the subject of channel capacity of quantum communication channels.
