International Conference on Quantum Physics of Nature (QuPoN 2015) Mitschnitt einer Veranstaltung der Fakultät für Physik am Montag, dem 18. Mai 2015 im Großen Festsaal der Universität Wien Teil 2. David Wineland: "Exploring quantum with trapped ions" Schnitt: Daniel Winkler Abstract: As a group, we live in an exciting time where we can explore some of the foundational issues in quantum mechanics and also look forward to possible applications of the techniques we develop. In this talk, I will try to highlight a few trapped-ion experiments in the general area of quantum information and quantum-limited measurements that enable us to investigate both of these areas. David Wineland ist Professor am National Institute of Standards and Technology (NIST) in Boulder (Colorado) und Nobelpreisträger für Physik des Jahres 2012.
