In the rapidly developing cold-atom-qubit platform, off-resonant modulated driving (ORMD) allows us to realize good two-qubit entangling gates. To achieve high fidelities with Rydberg-blockade gates under practical conditions, the high-frequency components in a modulation pattern must be dealt with. This study's filtering approach is applicable to constructing entangling gates that work at finite Rydberg-blockade strength, and to overcome the residual thermal motion of qubit atoms. These results are expected to provide an essential upgrade for such gates.
