Quantum computers hold the promise of solving certain computational tasks much more
efficiently than classical computers. We review recent experimental advances towards a …

The recent development of a range of new methods for producing samples of gas-phase
molecules that are translationally cold (K) or ultracold (mK) is driving efforts to study reactive …

Strong correlations—cooperative behavior due to many-particle interactions—are
omnipresent in nature. They occur in electrolytic solutions, dense plasmas, ultracold ions …

We investigate a surface-mounted electrode geometry for miniature linear radio frequency
Paul ion traps. The electrodes reside in a single plane on a substrate, and the …

Stationary molecules in well-defined internal states are of broad interest for physics and
chemistry. In physics, this includes metrology,,, quantum computing, and many-body …

Control over the motional degrees of freedom of atoms, ions, and molecules in a field-free
environment enables unrivalled measurement accuracies but has yet to be applied to highly …

Molecular hydrogen ions are of high interest in fundamental physics and metrology. In
particular, the long-range baryon–baryon interaction and the degrees of freedom of baryon …

We report a new experimental method to study reactive ion-molecule collisions at very low
temperatures. A source of laser-cooled ions in a linear Paul trap has been combined with a …

Cavity quantum electrodynamics (CQED) focuses on understanding the interactions
between matter and the electromagnetic field in cavities at the quantum level,. In the past …

Translationally cold, spatially localised molecular ions prepared by sympathetic cooling with
laser-cooled atomic ions in ion traps have recently found a wide range of applications in …
