Nanoscale addressing and manipulation of neutral atoms using electromagnetically induced transparency

We propose to integrate dark-state-based localization techniques into a neutral atom quantum computing architecture and numerically investigate two specific schemes. The first scheme implements state-selective projective measurement by scattering photons from a specific qubit with very little crosstalk on the other atoms in the ensemble. By exploiting the non-linearity of the Electromagnetically Induced Transparency effect, one can manipulate atoms on the optical lattice with a sub-wavelength resolution. The second scheme performs a single-qubit phase gate with high fidelity. Our numerical simulations in rubidium (Rb) atoms show that for both schemes a spatial resolution at the level of 10 nanometers using visible light can be achieved with experimentally realistic parameters.
