Measurement of electric-field noise from interchangeable samples with a trapped-ion sensor
Kyle S. McKay, Dustin A. Hite, Philip D. Kent +5
We demonstrate the use of a single trapped ion as a sensor to probe electric-field noise from interchangeable test surfaces. As proof of principle, we measure the magnitude and dis…
Crystallographic orientation dependence of work function: Carbon adsorption on Au surfaces
H. Z. Jooya, X. Fan, K. S. McKay +3
We investigate the work function (WF) variation of different Au crystallographic surface orientations with carbon atom adsorption. Ab-initio calculations within density-functional…
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…
Enhanced Superconducting Transition Temperature in Electroplated Rhenium
David P. Pappas, Donald E. David, Russell E. Lake +13
We show that electroplated Re films in multilayers with noble metals such as Cu, Au, and Pd have an enhanced superconducting critical temperature relative to previous methods of pr…
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…
