Abstract:
Trapped Rydberg ions are a novel quantum system [1,2], just recently observed for the first time [3,4]. They bring together two leading quantum technologies: trapped ions and Rydberg atoms. For trapped ions, this technology promises to speed up entanglement operations and make them available in larger ion crystals. I will present our recent experimental results using trapped 88Sr+ Rydberg ions. In particular, this includes the first coherent excitation of an ion to the Rydberg state, the realization of a single-qubit Rydberg phase gate [5], and the observation of Rydberg blockade between two microwave-dressed Rydberg ions. These are important steps towards realizing a quantum simulator with trapped Rydberg ions. [1] M. Müller, et al., New J. Phys. 10, 093009 (2008). [2] F. Schmidt-Kaler, et al., New J.
