Implementation of local and high-fidelity quantum conditional phase gates in a scalable two-dimensional ion trap
arXiv:0906.4598 · doi:10.1016/j.physleta.2010.01.035
Abstract
We propose a scheme to implement high-fidelity conditional phase gates on pair of trapped ions immersed in a two-dimensional Coulomb crystal, using interaction mediated by all axial modes without side-band addressing. We show through numerical calculations that only local modes can be excited to achieve entangling gates through shaping the laser beams, so that the complexity of the quantum gate does not increase with the size of the system. These results suggest a promising approach for realization of large scale fault-tolerant quantum computation in two dimensional traps architecture.
