Geometric quantum gate for trapped ions based on optical dipole forces induced by Gaussian laser beams
Peter Staanum, Michael Drewsen, Klaus Moelmer
We present an implementation of quantum logic gates via internal state dependent displacements of ions in a linear Paul trap caused by optical dipole forces. Based on a general qua…
Rotational cooling of heteronuclear molecular ions with ^1-Sigma, ^2-Sigma, ^3-Sigma and ^2-Pi electronic ground states
I. S. Vogelius, L. B. Madsen, M. Drewsen
The translational motion of molecular ions can be effectively cooled sympathetically to translational temperatures below 100 mK in ion traps through Coulomb interactions with laser…
Non-Destructive Identification of Cold and Extremely Localized Single Molecular Ions
M. Drewsen, A. Mortensen, R. Martinussen +2
A simple and non-destructive method for identification of a single molecular ion sympathetically cooled by a single laser cooled atomic ion in a linear Paul trap is demonstrated. T…
Rotational cooling of molecules using lamps
I. S. Vogelius, L. B. Madsen, M. Drewsen
We investigate theoretically the application of tailored incoherent far-infrared fields in combination with laser excitation of a single rovibrational transition for rotational coo…
Isotope shifts of the 4s2 1S0 -> 4s5p 1P1 transition and hyperfine splitting of the 4s5p 1P1 state in calcium
A. Mortensen, J. J. T. Lindballe, I. S. Jensen +3
Using a technique based on production of ion Coulomb crystals, the isotope shifts of the 4s2 1S0 -> 4s5p 1P1 transition for all naturally occurring isotopes of calcium as well as t…
