Summary We propose a solid-state quantum structure capable of generating Einstein-Podolsky-Rosen (EPR) electron pairs using a parametric electron pumping idea and the Coulomb blockade phenomenon. The quantum structure consists of two coupled quantum dots and four leads. Our scheme is easy to implement, and it does not impose special requirements on the leads. By employing the parametric pumping idea, harmful processes can be avoided and only two quantum dots are needed. Furthermore, the EPR electron pairs are spatially separated.
