Surface science motivated by heating of trapped ions from the quantum ground state
D. A. Hite, K. S. McKay, D. P. Pappas
For the past two and a half decades, anomalous heating of trapped ions from nearby electrode surfaces has continued to demonstrate unexpected results. Caused by electric-field nois…
Mechanisms for carbon adsorption on Au(110)-(2*1): A work function analysis
H. Z. Jooya, K. S. McKay, E. Kim +4
The variation of the work function upon carbon adsorption on the reconstructed Au(110) surface is measured experimentally and compared to density functional calculations. The adsor…
Measurements of trapped-ion heating rates with exchangeable surfaces in close proximity
D. A. Hite, K. S. McKay, S. Kotler +3
Electric-field noise from the surfaces of ion-trap electrodes couples to the ion's charge causing heating of the ion's motional modes. This heating limits the fidelity of quantum g…
Electric-field noise from carbon-adatom diffusion on a Au(110) surface: first-principles calculations and experiments
E. Kim, A. Safavi-Naini, D. A. Hite +4
The decoherence of trapped-ion quantum gates due to heating of their motional modes is a fundamental science and engineering problem. This heating is attributed to electric-field n…
