SAE-CAS reduces qubit requirements for quantum chemistry by extending symmetry-adapted mappings to frozen-core and virtual orbitals, integrates with Bravyi-Kitaev and point-group symmetries, and shows improved VQE performance on nine small molecules.

Quantum simulation methods for Thirring and Gross-Neveu fermionic models with arbitrary flavors, including gate complexity bounds and ground-state preparation up to 20 qubits.
TETRIS-ADAPT-VQE achieves fidelities above 99.3% for SYK (N=20) and 99.9998% for SK (L=18) but requires large resources for SYK models.
