Enhancing quantum utility: simulating large-scale quantum spin chains on superconducting quantum computers

Talal Ahmed Chowdhury, Kwangmin Yu, Mahmud Ashraf Shamim +2

We present the quantum simulation of the frustrated quantum spin-$\frac{1}{2}$ antiferromagnetic Heisenberg spin chain with competing nearest-neighbor $(J_1)$ and next-nearest-neig…
