The Institutes for Quantum Optics and Quantum Information (IQOQI) in Innsbruck and Vienna are part of the new Cluster of Excellence Quantum Science Austria (quantA), which was presented today in Vienna. Within the Cluster of Excellence, scientists in Innsbruck, Vienna, Linz and Klosterneuburg will jointly advance basic research in quantum science.
Researchers at ETH Zurich and TII Abu Dhabi, with the support of quantum optics theorists from Innsbruck, Austria, have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.
Trapped ions have previously only been entangled in one and the same laboratory. Now, teams led by Tracy Northup and Ben Lanyon from the University of Innsbruck have entangled two ions over a distance of 230 meters. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
When it comes to creating ever more intriguing quantum systems, a constant need is finding new ways to observe them in a wide range of physical scenarios. JILA Fellow Cindy Regal and JILA and NIST Fellow Ana Maria Rey have teamed up with Oriol Romero-Isart from the University of Innsbruck and IQOQI to show that a trapped particle in the form of an atom readily reveals its full quantum state with quite simple ingredients, opening up opportunities for studies of the quantum state of ever larger particles.
