Trapped Rydberg ions are a promising novel approach to quantum computing and
simulations. They are envisaged to combine the exquisite control of trapped ion qubits with …

We study photon scattering errors in stimulated Raman driven quantum logic gates. For
certain parameter regimes, we find that previous simplified models of the process …

Alkaline earth Rydberg atoms are very promising tools for quantum technologies. Their
highly excited outer electron provides them with the remarkable properties of Rydberg atoms …

Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions,
we perform a detailed study of electric dipole (E 1) transition amplitudes in K, Ca+, Rb, Sr+ …

Rydberg alkaline earth atoms are promising tools for quantum simulation and metrology.
When one of the two valence electrons is promoted to long-lived circular states, the second …

Measurement of the branching ratios for 6 P 1/2 decays to 6 S 1/2 and 5 D 3/2 in Ba+ 138
are reported with the decay probability from 6 P 1/2 to 5 D 3/2 measured to be p …

Accurate values of electric dipole (E1) amplitudes along with their uncertainties for a number
of transitions among low-lying states of Mg+, Ca+, Sr+, and Ba+ are listed by carrying out …

We study the time-dependent fluorescence of an initially hot, multilevel, single atomic ion
trapped in a radio-frequency Paul trap during Doppler cooling. We have developed an …

As measurement precision continues to advance, the accurate determination of multipolar
polarizabilities and hyperpolarizabilities becomes increasingly crucial for precisely …

Usually the influence of the quadratic Stark effect on an ion's trapping potential is minuscule
and only needs to be considered in atomic clock experiments. In this work we excite a …
