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.

Abstract

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.
