论文摘要
关于量子重力的一些深度猜想与对称性在重力背景中的作用密切相关，尤其是对于量子黑洞。在本文中，我们系统地研究了带电的混乱系统的量子信息理论。我们展示了整个系统中的量子信息如何使用量子混乱和量子误差校正理论代表其电荷扇区，并在复杂的SYK模型的背景下使用具体示例。我们讨论了对动态设置中关于量子重力的黑洞思维实验的可能影响。我们认为，这项工作将具有从量子重力理论到量子设备中的量子模拟的潜在应用。
Some deep conjectures about quantum gravity are closely related to the role of symmetries in the gravitational background, especially for quantum black holes. In this paper, we systematically study the theory of quantum information for a charged, chaotic system. We show how the quantum information in the whole system has been represented by its charge sectors, using the theory of quantum chaos and quantum error correction, with concrete examples in the context of the complex SYK model. We discuss possible implications for black hole thought experiments and conjectures about quantum gravity in the dynamical setup. We believe this work will have potential applications from theories of quantum gravity to quantum simulation in quantum devices.
