A Quantum Processor with Trapped (Rydberg) Ions _ **A Quantum Processor with Trapped (Rydberg) Ions **_ ** _Markus Hennrich_** Institute for Experimental Physics, University of Innsbruck Abstract: Cold trapped ions are well isolated from the environment and can be coherently manipulated by laser light. This makes them a useful system for building a quantum computer on which one can test quantum algorithms and simulations. In the first part of my talk, I will introduce trapped ions as a quantum system and discuss their application for quantum information processing. Then I will present some of our recently realised algorithms, in particular, the generation of GHZ states of up to 14 ion qubits, and the realization of open-system and digital quantum simulations. In the second part of my talk I will describe a novel approach that will combine two technologies for quantum systems: trapped ions and Rydberg atoms. This idea promises to join the advanced quantum control of trapped ions with the strong dipolar interaction between Rydberg atoms. This approach will form a novel quantum system with advantages from both sides. In particular, it promises to speed up entangling interactions and to make such operations possible in larger ion crystals.
