Q-MCC: Quantum Molecular Conformer Classifier — Chemical Accuracy on IBM Torino (133-qubit Heron r1)

We present Q-MCC (Quantum Molecular Conformer Classifier), a variational quantum algorithm for molecular conformer screening validated on IBM Torino (133-qubit Heron r1 processor). Using 111 QPU jobs executed during the cycle 02.02–02.03.2026, we achieved chemical accuracy with Δ_FCI = 0.24 mHartree (threshold: 1.6 mHartree), confirmed 6 independent times. Q-MCC correctly identified the H₂ equilibrium geometry at r = 0.735 Å with 100% accuracy. Multi-molecule results include H₂ (2 qubits), LiH (4 qubits), and BeH₂ (6 qubits).
