Effective Noise Mitigation via Quantum Circuit Learning in Quantum Simulation of Integrable Spin Chains
Wenlong Zhao, Yimeng Zhang, Yan Guo +3
We propose a noise-mitigation quantum simulation strategy for near-term quantum devices based on Quantum Circuit Learning (QCL), which is in particular effective for integrable qua…
Effective Bethe Ansatz for Spin-1 Non-integrable Models
Zhuohang Wang, Rui-Dong Zhu
This work presents a comprehensive benchmark and validation of a recently proposed method called Effective Bethe Ansatz (EBA). It is a variational method that deforms the exact Bet…
The Roaming Bethe Roots: An Effective Bethe Ansatz Beyond Integrability
Wenlong Zhao, Yunfeng Jiang, Rui-Dong Zhu
We propose an effective Bethe ansatz (EBA) for solving quantum many-body systems near an integrable point. Our approach retains the functional form of the Bethe wave function while…
Bethe/Gauge correspodence: a short review on an aspect of the integrability nature of supersymmetric gauge theories
Rui-Dong Zhu
In this article, we provide a short review (written in Chinese) on the Bethe/Gauge correspondence. We first explain the basic idea in an explicit example of the correspondence betw…
Bethe/Gauge Correspondence for Spin Chains with Integrable Boundaries
Ziwei Wang, Rui-Dong Zhu
We continue the survey initiated in arXiv:2012.14197 to explore the Bethe/Gauge correspondence between supersymmetric SO/Sp gauge theories in 2d/3d/4d and open spin chain with inte…
