    "abstract": "An array of planar Penning traps, holding single electrons, can realize an\nartificial molecule suitable for NMR-like quantum information processing. The\neffective spin-spin coupling is accomplished by applying a magnetic field\ngradient, combined to the Coulomb interaction acting between the charged\nparticles. The system lends itself to scalability, since the same substrate can\neasily accommodate an arbitrary number of traps. Moreover, the coupling\nstrength is tunable and under experimental control. Our theoretical predictions\ntake into account a realistic setting, within the reach of current technology.",
