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