 A phase gate and a melmas rents in gate in the dress state basis are proposed using resonant microwave driving fields, either with an RF or detuned microwave driving field, to perform multi-qubit interaction in a strong magnetic field gradient. The gate is robust to ambient magnetic field fluctuations and phone under phasing due to applied resonant microwave driving fields, making it an attractive candidate for high-fidelity microwave-based multi-qubit gates that can be realized in laser-based setups.
