Researchers achieved the first coherent population transfer between Rydberg states of a trapped ion, reaching 91.5% efficiency with a single microwave π-pulse, marking a breakthrough in quantum state control. The team demonstrated microwave-mediated Rabi oscillations between Rydberg S and P states, enabling precise manipulation of atomic states critical for quantum computing and simulation applications. Microwave dressing hybridized S and P states into tunable eigenstates with adjustable polarizability, allowing both noise-resilient zero-polarizability states and strongly interacting configurations. Adiabatic transfer between zero-polarizability and maximally dressed states was proven, combining noise resistance with strong dipole-dipole interactions in a single experimental sequence. This advancement enables Förster resonance control within trapped ion systems, potentially accelerating progress in quantum networking and error-resilient quantum information processing.

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 ${\pi}$-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.
