Andreev tunneling, Coulomb blockade, and resonant transport of nonlocal spin-entangled electrons
Andreev tunneling, Coulomb blockade, and resonant transport of nonlocal spin-entangled electrons
We propose and analyze a spin-entangler for electrons based on an s-wave superconductor coupled to two quantum dots, each of which is coupled to normal Fermi leads. We show that in the presence of a voltage bias and in the Coulomb blockade regime two correlated electrons provided by the Andreev …
