Abstract
As a demonstration of thespectrum-parity matching condition (SPMC) forquantum state transfer, we investigate the propagation of single-magnonstate in the Heisenberg chain in the confined external tangent magneticfield analytically and numerically. It shows that the initial Gaussian wavepacket can be retrieved at the counterpart location near-perfectly over alonger distance if the dispersion relation of the system meets the SPMCapproximately.
