A Discrete Recovery Failure Mode in Sample-Based Quantum Diagonalization Carries Chemically Predictive Information

Sample-based quantum diagonalization (SQD) recovers a molecular ground state from noisy quantum-hardware samples by iteratively selecting a subspace of Slater determinants and diagonalizing the Hamiltonian within it. We show that this recovery process can become trapped in a repr...
