摘要:

本文提出了一种基于变分量子算法的量子光学系统的数值模拟方法。更确切地说,我们引入了一个短深度变分形式,在量子处理器上准备多模Dicke模型的基态,并通过云访问IBM设备获得了原理证明结果。此外,我们提供了一个算法,用于表征基态的维格纳态层析成像。我们的工作是量子光学系统的数字量子模拟的第一步,具有潜在的应用自旋玻色子,近藤和Jahn-Teller模型。

英文摘要:

We propose the simulation of quantum-optical systems in the ultrastrong-coupling regime using a variational quantum algorithm. More precisely, we introduce a short-depth variational form to prepare the groundstate of the multimode Dicke model on a quantum processor and present proof-of-principle results obtained via cloud access to an IBM device. We moreover provide an algorithm for characterizing the groundstate by Wigner state tomography. Our work is a first step towards digital quantum simulation of quantum-optical systems with potential applications to the spin-boson, Kondo and Jahn-Teller models.
