Numerical solution of the nonlinear Dirac equation by a splitting variational quantum algorithm

Qian Zuo, Ying He, Xiaofei Zhao

In this work, we propose an operator-splitting variational quantum algorithm, termed Dirac-sVQA, for simulating the nonlinear Dirac equation (NLDE). The main difficulty arises from…

On the Polyak momentum variants of the greedy deterministic single and multiple row-action methods

Nian-Ci Wu, Qian Zuo, Yatian Wang

For solving a consistent system of linear equations, the classical row-action (also known as Kaczmarz) method is a simple while really effective iteration solver. Based on the gree…
