Abstract

We investigate the entanglement transfer in two parallel spin chains by anisotropic Heisenberg XY interaction in an external magnetic field. The perfect entanglement transfer condition is obtained. We find that perfect entanglement transfer can be realized from one spin pair to another spin pair at certain times by adjusting the magnetic field strength and the anisotropy parameter, which suggests its potential usefulness in quantum information process.
