DESCRIPTION:Speakers: Robin Frederick Thomm (Stockholm University)\n\nAbst
 ractTrapped ions are one of the leading platforms for quantum technologies
  due to their excellent control over their internalelectronic and external
  motional degrees of freedom. Many techniques and interesting effects rely
  on the coupling of theions to their motion\, which makes precise control 
 of them paramount.In this work\, two novel techniques for motional state d
 etection are presented. They allow the probing of certain motionalstates w
 ith a single measurement\, without affecting the motion of the measured io
 n. These techniques are employed togenerate and detect a highly entangled 
 state between two motional modes in a novel manner. Furthermore\, we harne
 ss therich and intricate dynamics arising from the coupling of the ion's m
 otion to its electronic degrees of freedom to study theemergence of interf
 erence. Theoretical predictions\, describing interference both in the quan
 tum and the classical regimes\,are verified\, offering a new and more intu
 itive description of interference\, not just for trapped ions\, but for a 
 variety ofsystems that can be described in a similar way.On the other hand
 \, Rydberg excitation with trapped ions enables new interaction mechanisms
  and makes them extremelysensitive to their surroundings. This thesis pres
 ents advances towards Rydberg experiments with longer ion strings andconcl
 udes with a first demonstration of coherent population transfer between Ry
 dberg states in trapped ions. The methodsdeveloped significantly increase 
 the toolbox for trapped Rydberg ions\, enabling more sophisticated experim
 ents\, especiallywhen multiple different Rydberg states are involved\, and
  allow more flexibility when using longer ion strings.\n\nhttps://indico.f
