Scientific paper

We propose a mechanism for perfect entanglement transport in anti-ferromagnetic (AFM) quantum spin chain systems with modulated exchange coupling along the xy plane and in the z direction. We use the principle of adiabatic quantum pumping process for entanglement transfer in the spin chain systems. In our proposed mechanism, perfect entanglement transfer can be achieved over an arbitraly long distance. We explain analytically and physically why the entanglement hops in alternate sites. We solve this problem by using the Berry phase analysis and Abelian bosonization methods. We find the condition for blocking of entanglement transport even in the perfect pumping condition. We also explain physically why entanglement transfer in AFM chain out performs the ferromagnetic chain. Our analytical solution interconnects quantum many body physics and quantum information science.
