摘要:
在文献[1]中,我们讨论了如何利用量子器件模拟量子引力,并给出了一个具体方案——通过尺寸的隐形传态以及尺寸缠绕现象。在这里,我们阐述在“实验室中研究量子引力”的含义,以及尺寸缠绕如何与体引力物理和可穿越虫洞相联系。完美尺寸缠绕是算符尺寸波函数的一项非凡的细粒度性质;我们通过一项体计算表明,对于具有近 AdS_2 体的量子系统,这一性质必然成立。随后,我们详细考察了三个系统中的通过尺寸的隐形传态:Sachdev-Ye-Kitaev 模型、随机矩阵和自旋链,并讨论了在近期量子器件中实现这些现象的前景。
英文摘要:
In [1] we discussed how quantum gravity may be simulated using quantum devices and gave a specific proposal -- teleportation by size and the phenomenon of size-winding. Here we elaborate on what it means to do 'Quantum Gravity in the Lab' and how size-winding connects to bulk gravitational physics and traversable wormholes. Perfect size-winding is a remarkable, fine-grained property of the size wavefunction of an operator; we show from a bulk calculation that this property must hold for quantum systems with a nearly-AdS_2 bulk. We then examine in detail teleportation by size in three systems: the Sachdev-Ye-Kitaev model, random matrices, and spin chains, and discuss prospects for realizing these phenomena in near-term quantum devices.
