  Thermoelectric effect generating electricity from thermal gradient and vice
versa appears in numerous generic applications. Recently, an original prospect
of thermoelectricity arising from the nonlocal Cooper pair splitting (CPS) and
the elastic co-tunneling (EC) in hybrid normal metal-superconductor-normal
metal (NSN) structures was foreseen. Here we demonstrate experimentally the
existence of non-local Seebeck effect in a graphene-based CPS device comprising
two quantum dots connected to an aluminum superconductor and theoretically
validate the observations. This non-local Seebeck effect offers an efficient
tool for producing entangled electrons.
