EHA in Sequential-ADAPT-VQE (Entanglement-variational Hardware-efficient Ansatz in Sequential-ADAPT-VQE) significantly enhances variational quantum algorithms (VQAs) for optimizing Noisy Intermediate-Scale Quantum (NISQ) devices. By dynamically selecting single-qubit gates and reducing reliance on CNOT gates, this method constructs more efficient quantum circuits, reducing quantum resource demands and improving computational accuracy. EHA notably improves Sequential-ADAPT-VQE, showing strong robustness across different initial states.
