This paper addresses high-fidelity Bell state preparation under depolarizing noise. A split-qubit approach is proposed: dynamic decoupling for the control qubit and error correction for the target qubit. Qiskit simulations show fidelity maintained at 1.0000, with error rates reduced from ~24% to 0.4%, requiring only four X gates. The method achieves low-complexity, high-fidelity entanglement preparation.
