Effective Noise Mitigation via Quantum Circuit Learning in Quantum Simulation of Integrable Spin Chains
Wenlong Zhao, Yimeng Zhang, Yan Guo +3
The paper introduces a noise‑mitigation approach for near‑term quantum devices that uses Quantum Circuit Learning to train shallow variational circuits to approximate deeper time‑e…
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 for solving quantum many-body systems near an integrable point. Our approach retains the functional form of the Bethe wave function while renor…
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…
