Multi-GHz repetition rate, multi-watt average power, ultraviolet laser pulses for fast trapped-ion entanglement operations
M. I. Hussain, D. Heinrich, M. Guevara-Bertsch +4
The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow proce…
Frequency measurement of the transition of Al via quantum logic spectroscopy with Ca
Michael Guggemos, Milena Guevara-Bertsch, Daniel Heinrich +4
We perform quantum logic spectroscopy with a Al/Ca mixed ion crystal in a linear Paul trap for a measurement of the $(3s^{2})\,^{1}\mathrm{S}_{0} \leftrig…
Ultrafast coherent excitation of a Ca ion
D. Heinrich, M. Guggemos, M. Guevara-Bertsch +3
Trapped ions are a well-studied and promising system for the realization of a scalable quantum computer. Faster quantum gates would greatly improve the applicability of such a syst…
Sympathetic cooling and detection of a hot trapped ion by a cold one
M. Guggemos, D. Heinrich, O. A. Herrera-Sancho +2
We investigate the dynamics of an ion sympathetically cooled by another laser-cooled ion or small ion crystal. To this end, we develop simple models of the cooling dynamics in the…
