Title: "Quantum logic with trapped ions: precise, fast, networked"
The concepts of quantum information processing date back at least 35 years, to the ideas of quantum simulation and computing suggested by Feynman and Deutsch respectively. Experimental progress in the field often appears slow, partly because of the demanding precision required in the elementary logic operations for quantum error correction, partly because of the technical challenges associated with scaling systems up to larger numbers of qubits, and partly because our expectations are coloured by the enormous power and progress of classical computing technology over the last hundred years. I will give a brief survey of the state of the art across the various platforms which are being explored for quantum computing, and show that progress is in fact extremely encouraging. I will then report on recent work in Oxford on improving the precision and speed of quantum logic operations in the ion trap platform, and on building an elementary quantum network to distribute entanglement between two different ion trap "nodes" separated by macroscopic distances.
