Abstract
We investigate the effect of phase shift on the entanglement transfer in two parallel 1D spin chains. We calculate the concurrence, measures for two-qubit entanglement, as a function of time. We find the maximum achievable entanglement in the cases with and without phase shift. Although the entanglement transfer becomes slow in most cases with phase shift, the significant enhancement of the maximum achievable entanglement is obtained which suggests its potential usefulness in quantum information processing.
