论文摘要
在过去的二十年中，通过实验进步和全息二元性带来的新的强大理论方法助长了各种先前相关的学科，例如凝结物质，核物理学，重力和量子信息等各种先前相关的学科，例如凝结物质，核物理学，重力和量子信息。在这项非技术综述中，我们对与量子多体动力学有关的全息二元性进行了一些最新进展。这些包括对没有准颗粒的密切相关相的见解及其传输特性，量子多体混乱以及量子信息的争夺。我们还讨论了使用量子信息理解全息二元性本身结构的最新进展，包括二元性的“局部”版本以及具有重力双重双体量子状态的量子误差校正解释，以及此类概念如何帮助证明黑洞蒸发的单位性。
The last two decades have seen the emergence of stunning interconnections among various previously remotely related disciplines such as condensed matter, nuclear physics, gravity and quantum information, fueled both by experimental advances and new powerful theoretical methods brought by holographic duality. In this non-technical review we sample some recent developments in holographic duality in connection with quantum many-body dynamics. These include insights into strongly correlated phases without quasiparticles and their transport properties, quantum many-body chaos, and scrambling of quantum information. We also discuss recent progress in understanding the structure of holographic duality itself using quantum information, including a "local" version of the duality as well as the quantum error correction interpretation of quantum many-body states with a gravity dual, and how such notions help demonstrate the unitarity of black hole evaporation.
