    "abstract": "We show that a large number of ions stored in a Penning trap, and forming a\n2D Coulomb crystal, provides an almost ideal system for scalable quantum\ncomputation and quantum simulation. In particular, the coupling of the internal\nstates to the motion of the ions transverse to the crystal plane, allows one to\nimplement two qubit quantum gates. We analyze in detail the decoherence induced\nby anharmonic couplings with in--plane hot vibrational modes, and show that\nvery high gate fidelities can be achieved with current experimental set--ups.",
