This letter is devoted to the optimization of the Cooper pair splitting efficiency in a Y-shaped junction. The latter consists of two quantum dots, one superconducting and two normal leads. We tailor the bias in the two normal leads such that the Cooper pairs leaving the superconductor are split up resulting in entangled electrons, one on each quantum dot. We are able to achieve a splitting efficiency of more than 99% which is significantly better than the efficiencies obtained in experiments so far.
