Probing the limits of variational quantum algorithms for nonlinear ground states on real quantum hardware: The effects of noise
Muhammad Umer, Eleftherios Mastorakis, Sofia Evangelou +1
A recently proposed variational quantum algorithm has expanded the horizon of variational quantum computing to nonlinear physics and fluid dynamics. In this work, we probe the abil…
