We report the experimental observation of Coulomb drag in two parallel, ballistic quantum wires fabricated from a high-mobility 2DEG at the interface of a AlGaAs=GaAs heterostructure and deΓΏned by three independent Schottky gates. The Coulomb drag resistance R D in wire 1 due to a drive current in w
