摘要：
We demonstrate that spin chains are experimentally feasible using electrons confined in micro-Penning traps, supplemented with local magnetic field gradients. The resulting Heisenberg-like system is characterized by coupling strengths showing a dipolar decay. These spin chains can be used as a channel for short-distance quantum communication. Our scheme offers high accuracy in reproducing an effective spin chain with relatively large transmission rate.
