    "abstract": "As a demonstration of the spectrum-parity matching condition (SPMC) for\nquantum state transfer, we investigate the propagation of single-magnon state\nin the Heisenberg chain in the confined external tangent magnetic field\nanalytically and numerically. It shows that the initial Gaussian wave packet\ncan be retrieved at the counterpart location near-perfectly over a longer\ndistance if the dispersion relation of the system meets the SPMC approximately.",
