We study the noise properties of a double quantum dot driven by an AC electric field that pumps electrons between two unbiased leads. In the presence of a static magnetic field, it is possible to tune the gate voltage such that the resulting current consists mainly of spin-polarized electrons. We find that for particular driving amplitudes, the current is quenched and possesses super-Poissonian shot noise.
