This projects aims at a single electron pair source which delivers (in principle) on demand pairs of spin-entangled electrons, whereof each electron may leave the device through different arms. While similar photonic EPR sources are widely used in optics in

Carbon nanotubes (CNTs) are almost ideal one-dimensional conductors. However, potential variation caused likely by charge tarps in the substrate induced backscatering on a length scale of a few 100 nm. There are two strategies to overcome this problem: in one
