Frequency Metrology on single trapped ions in the weak binding limit: The 3s1/2-3p3/2 transition in 24-Mg+
M. Herrmann, V. Batteiger, S. Knünz +3
We demonstrate a method for precision spectroscopy on trapped ions in the limit of unresolved motional sidebands. By sympathetic cooling of a chain of crystallized ions we suppress…
Sub-Hz line width diode lasers by stabilization to vibrationally and thermally compensated ULE Fabry-Perot cavities
J. Alnis, A. Matveev, N. Kolachevsky +3
We achieved a 0.5 Hz optical beat note line width with ~ 0.1 Hz/s frequency drift at 972 nm between two external cavity diode lasers independently stabilized to two vertically moun…
Photoionization Broadening of the 1S-2S Transition in a Beam of Atomic Hydrogen
N. Kolachevsky, M. Haas, U. D. Jentschura +7
We consider the excitation dynamics of the two-photon \sts transition in a beam of atomic hydrogen by 243 nm laser radiation. Specifically, we study the impact of ionization dampin…
Microwave potentials and optimal control for robust quantum gates on an atom chip
Philipp Treutlein, Theodor W. Hänsch, Jakob Reichel +3
We propose a two-qubit collisional phase gate that can be implemented with available atom chip technology, and present a detailed theoretical analysis of its performance. The gate…
