Electric field noise in a high-temperature superconducting surface ion trap
Philip C. Holz, Kirill Lakhmanskiy, Dominic Rathje +3
Scaling up trapped-ion quantum computers requires new trap materials to be explored. Here, we present experiments with a surface ion trap made from the high-temperature superconduc…
Motion analysis of a trapped ion chain by single photon self-interference
G. Cerchiari, G. Araneda, L. Podhora +3
We present an optical scheme to detect the oscillations of a two-ion string confined in a linear Paul trap. The motion is detected by analyzing the intensity correlations in the fl…
Measuring ion oscillations at the quantum level with fluorescence light
G. Cerchiari, G. Araneda, L. Podhora +3
We demonstrate an optical method for detecting the mechanical oscillations of an atom with single-phonon sensitivity. The measurement signal results from the interference between t…
The Panopticon device: an integrated Paul-trap-hemispherical mirror system for quantum optics
Gabriel Araneda, Giovanni Cerchiari, Daniel B. Higginbottom +5
We present the design and construction of a new experimental apparatus for the trapping of single Ba ions in the center of curvature of an optical-quality hemispherical mirror.…
Probing surface charge densities on optical fibers with a trapped ion
Florian R. Ong, Klemens Schüppert, Pierre Jobez +8
We describe a novel method to measure the surface charge densities on optical fibers placed in the vicinity of a trapped ion, where the ion itself acts as the probe. Surface charge…
Two-dimensional linear trap array for quantum information processing
Philip C. Holz, Silke Auchter, Gerald Stocker +8
We present an ion-lattice quantum processor based on a two-dimensional arrangement of linear surface traps. Our design features a tunable coupling between ions in adjacent lattice…
