Periodic Symmetry-Adapted Encoding: Qubit Reduction in Crystalline Electronic Structure

arXiv:2606.05777v1 Announce Type: new Abstract: We extend the symmetry-adapted encoding (SAE) framework to periodic electronic structure, enabling qubit-efficient quantum simulation of crystalline materials. By constructing a $\Gamma$-point supercell Hamiltonian from a folded $k$-point calculation
