Temperature Dependence of Electric Field Noise above Gold Surfaces
Jaroslaw Labaziewicz,Yufei Ge,David R. Leibrandt,Shannon X. Wang,Ruth Shewmon,Isaac L. Chuang +5 more
TL;DR: Measurements characterizing the temperature and frequency dependence of the noise from 7 to 100 K, using a single Sr+ ion trapped 75 mum above the surface of a gold plated surface electrode ion trap, show noise amplitude to have an approximate 1/f spectrum around 1 MHz.
Superconducting microfabricated ion traps
Shannon X. Wang,Yufei Ge,Jaroslaw Labaziewicz,Eric A. Dauler,Karl K. Berggren,Isaac L. Chuang +5 more
TL;DR: Wang et al. as discussed by the authors proposed a superconducting microfabricated ion trap with a superconductor and showed that the trap can be used to detect the presence of ion traps.

Individual addressing of ions using magnetic field gradients in a surface-electrode ion trap
TL;DR: In this paper, the authors demonstrate individual addressing of trapped ions in a microfabricated surface-electrode trap using a magnetic field gradient generated on-chip, achieving a frequency splitting of 310(2) kHz for two ions separated by 5 µm.

One-dimensional array of ion chains coupled to an optical cavity
Marko Cetina,Alexei Bylinskii,Leon Karpa,Dorian Gangloff,Kristin M. Beck,Yufei Ge,Matthias Scholz,Andrew T. Grier,Isaac L. Chuang,Vladan Vuletic +9 more
TL;DR: In this paper, an optical cavity is integrated with an amicrofabricated planar electrode iontrap, allowing the trapping of up to 50 separate ion chains aligned with the cavity and spaced by 160 µm in a one-dimensional array along the cavity axis.
Individual addressing of ions using magnetic field gradients in a surface-electrode ion trap
TL;DR: In this article, the authors demonstrate individual addressing of trapped ions in a microfabricated surface-electrode trap using a magnetic field gradient generated on-chip, achieving a frequency splitting of 310(2) kHz for two ions separated by 5 um.
