RT Journal Article T1 Quantum manipulation of trapped ions in two dimensional Coulomb crystals A1 Porras Torres, Diego A1 Cirac, J. Ignacio AB We show that a large number of ions forming a 2D Coulomb crystal provides an almost ideal system for scalable quantum computation and quantum simulation. In particular, the coupling of the internal states to the motion of the ions transverse to the crystal plane allows one to implement two-qubit quantum gates. We analyze in detail the decoherence induced by anharmonic couplings, and show that very high gate fidelities can be achieved with current experimental setups.
