We study electron transport through a normal lead-quantum dot-topologicalsuperconductor-quantum dot-normal lead (N-QD-TS-QD-N) junction. Due to thenon-local nature of Majorana fermions (MFs) in the topological superconductor,there are two types of single electron transport processes in the junction:crossed Andreev reflection (CAR) and electron teleportation (ET). When thecoupling energy of MFs is much larger than the coupling between MFs and QDs,electron can tunnel through topological superconductor either via CAR or ETdepending on the energy levels of QDs. For instance, when both energies of QDs(labeled as $\epsilon_1$ and $\epsilon_2$) are equal to the coupling energy ofMFs (denoted as $E_M$), the electron in the left lead can teleport to the rightlead via MFs while when $\epsilon_1=-\epsilon_2=E_M$ is satisfied, the electronin the left lead can combine one electron in the right lead to form a cooperpair and tunnel into the topological superconductor via MFs. Since bothelectron teleportation and crossed Andreev reflection manifest the non-localproperties of MFs, they can be used to examine the nature of MFs.
