Query: Fast and robust magnon transport in a spin chain   A protocol for fast and robust magnon transport in a one-dimensional spin
chain is devised. Employing an approximate mapping between the chain and a
single harmonically trapped particle, we exploit the known analytic control
protocols for the latter and adopt them to achieve fast, high-fidelity
transport in the chain. We compare the performance with finite time adiabatic
protocols, establishing that the designed scheme allows for significantly
faster and more stable transport. Furthermore, we show that a sharp transition
exists between regions in which the protocol is effective and when it breaks
down, giving rise to a heuristic speed limit for the process.
