Improved high-fidelity transport of trapped-ion qubits through a multi-dimensional array
R. B. Blakestad, C. Ospelkaus, A. P. VanDevender +4
We have demonstrated transport of Be+ ions through a 2D Paul-trap array that incorporates an X-junction, while maintaining the ions near the motional ground-state of the confining…
A 750 mW, continuous-wave, solid-state laser source at 313 nm for cooling and manipulating trapped 9Be+ ions
Andrew. C. Wilson, Christian Ospelkaus, Aaron. P. VanDevender +4
We present a solid-state laser system that generates 750 mW of continuous-wave single-frequency output at 313 nm. Sum-frequency generation with fiber lasers at 1550 nm and 1051 nm…
Microwave quantum logic gates for trapped ions
C. Ospelkaus, U. Warring, Y. Colombe +4
Control over physical systems at the quantum level is a goal shared by scientists in fields as diverse as metrology, information processing, simulation and chemistry. For trapped a…
Single-qubit-gate error below 10^-4 in a trapped ion
K. R. Brown, A. C. Wilson, Y. Colombe +5
With a 9Be+ trapped-ion hyperfine-states qubit, we demonstrate an error probability per randomized single-qubit gate of 2.0(2) x 10^-5, below the threshold estimate of 10^-4 common…
