Our approach is based on the projected entangled pair operator (PEPO) in the Heisenberg picture. Its main feature is the ability to automatically identify the underlying low-rank and low-entanglement structures in the quantum circuit involving Clifford and near-Clifford gates.\n  We assess our approach using the quantum circuit with 5+1 trotter steps which was previously considered beyond classical verification.
