By coupling two quantum dots via a superconductor-semiconductor hybrid region in a 2D electron gas, the authors achieve efficient splitting of Cooper pairs. Further, by applying a magnetic field perpendicular to the spin-orbit field, they can induce and measure large triplet correlations in the Cooper pair splitting process.
