Phys. Rev. A 75, 032348 (2007) [10 pages]Spin chains with electrons in Penning trapsReceived 29 September 2006; published 30 March 2007 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. © 2007 The American Physical Society URL:
