A weakly bound electron in a semiconductor quantum wire is shown to become entangled with an itinerant electron via the Coulomb interaction. The degree of entanglement and its variation with energy of the injected electron, may be tuned by choice of spin and initial momentum. Full entanglement is achieved close to energies where there are spin-dependent resonances. Possible realisations of related device structures are discussed.
