Rydberg trapped ions, a novel platform for quantum computing, quantum simulation and sensing — •Arezoo Mokhberi1, Jonas Vogel1, Justas Andrijauskas1, 2, Ron Müller1, and Ferdinand Schmidt-Kaler1, 2 — 1QUANTUM, Institut für Physik, Universität Mainz, D-55128 Mainz, Germany — 2Helmholtz-Institut Mainz, D-55128 Mainz, Germany
Cold and controlled atoms and ions are currently of great interest for applications in quantum information processing, simulation and sensing. Excitation of trapped ions to their Rydberg states offers a unique opportunity for combining advantages of precisely controllable trapped-ion qubits with long-range and tunable Rydberg interactions [1,2]. As an exciting application, we proposed a method for fast entangling operations using Rydberg trapped ions which are shuttled in a Paul trap [3]. The state-dependent kick is resulted from impulsive electric pulses [4] acting on ions in Rydberg states with huge polarizability, and it gives rise to a geometric phase that is controlled using experimental parameters [3]. We also discuss our new experimental setup in Mainz which is designed for coherent manipulation of Rydeberg states of 40Ca+ ions using a two-photon process, and present our results for Rydberg spectroscopy of S and D series.
