• Abstract: Microwave dressing of Rydberg ions creates tunable eigenstates with controllable polarizability and interaction strength, but coherent navigation between these states has remained elusive. Here, we report on the first demonstration of coherent population transfer between different Rydberg states of a trapped ion. We investigate both microwave-mediated Rabi oscillations between Rydberg S and P states and adiabatic transfer between microwave-dressed Rydberg states. Between Rydberg S and P states we achieve a population transfer efficiency of 91.5(5)% in a single microwave $π$-pulse. Microwave dressing hybridizes the S and P Rydberg states into new eigenstates with tunable polarizability, enabling both noise-resilient zero-polarizability states and maximally interacting states. We demonstrate adiabatic transfer between these zero-polarizability and maximally dressed states, enabling experiments that combine noise-resilient excitation with strong dipole-dipole interactions and Förster resonance control within a single measurement sequence.

• Selective Rydberg pumping via strong dipole blockade [0.0]
  We propose one type of selective Rydberg pumping mechanism. In the computational basis of two atoms $|00rangle, |01rangle,|10rangle,|11rangle$, this mechanism allows $|11rangle$ to be resonantly pumped upwards to the single-excited Rydberg states. The performance of this selective Rydberg pumping is evaluated using the definition of fidelity for controlled-$Z$ gate.
