R Gupta, Jabez J. McClelland, Zeina J. Kubarych, Robert Celotta
Fabrication of a two-dimensional array of nanometer-scale chromium features on a silicon substrate by laser-focused atomic deposition is described. Features 13plus or minus}1 nm high and having a full-width at half maximum of 80plus or minus}10 nm are

Experiments at NIST with Trapped Ions: 3-D Zero-Point Cooling, Quantum Gates, Bragg Scattering, and Atomic Clocks

We have recently used stimulated-Raman transitions in the resolved sideband regime to cool single ions to the n = 0 zero-point energy. This has allowed realizations of the Jaynes-Cummings model interaction for atomic motion and a quantum controlled-NOT
