abstract = {Combining the strong and long-range interaction of cold
Rydberg atoms with the controllability of trapped ions,
ultracold trapped Rydberg ions provide a promising platform
for scalable quantum computing. We demonstrate how
microwave-dressed Rydberg states result in rotating
permanent dipole moments causing strong dipole-dipole
interaction between ions in highly excited Rydberg states.
Due to the large difference in time scales, the fast
electronic dynamics of the Rydberg ions decouple from the
slower oscillator modes in the linear Coulomb crystal. These
properties allow us to realize a submicrosecond two-qubit
gate between two Rydberg ions confined in a Paul trap
reaching fidelities of > $99\%$ under consideration of the
finite lifetime of the Rydberg states at room temperature.},
