Rainer Blatt

Rainer Blatt (born September 8, 1952 in Idar-Oberstein ) is a German-Austrian experimental physicist . He conducts research in the field of quantum optics and quantum information and was the first to conduct quantum teleportation with atoms with his team .

Life

Rainer Blatt studied physics at the University of Mainz and graduated in 1979 with a diploma. In 1981 he received his doctorate and then worked as a research assistant with Günter Werth . In 1982, Blatt went to the Joint Institute for Laboratory Astrophysics (JILA), Boulder , to study with John L. Hall (Nobel Prize 2005) with a research grant from the German Research Foundation (DFG ). In 1983 he moved to the Free University of Berlin and a year later to the working group of Peter E. Toschek at the University of Hamburg . After a further stay in the USA , Rainer Blatt completed his habilitation in experimental physics in 1988 . From 1989 to 1994 he did research as a Heisenberg fellow at the University of Hamburg and during this time spent several research stays at JILA in Boulder. In 1994 he was appointed professor of physics at the University of Göttingen . A year later, he was appointed to a chair for experimental physics at the University of Innsbruck . Blatt headed the Institute for Experimental Physics from 2000 to 2013 and is a member of the academic senate. Since 2003 he has also been Scientific Director at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW). Rainer Blatt is married with three children and lives in Inzing .

Act

The experimental physicist Rainer Blatt carried out pioneering experiments in the field of precision spectroscopy , quantum metrology and quantum information processing . He works with atoms stored in ion traps , which are manipulated with the help of laser beams . This work was based on suggestions made by theoreticians Ignacio Cirac and Peter Zoller in the mid-1990s. In the structure proposed by them, Blatt's working group succeeded for the first time in 2004 in transferring the quantum information from one atom to another atom in a fully controlled manner ( quantum teleportation ). The science magazine Nature reported on it and dedicated a front page to the successful experiment. While only three particles were arranged in an ion trap for this experiment, Rainer Blatt's group managed to entangle up to eight atoms in a controlled manner two years later. The generation of the first "quantum byte" (1 qubyte consists of 8 qubits ) is a further step on the way to the quantum computer .

Blatt and colleagues also carried out the experimental implementation of error corrections in quantum computers (2011), an essential component of quantum computers, as these are very error-prone and will never work properly. In the first experimental arrangement of three entangled qubits as calcium ions in an ion trap, two of the qubits served as correction qubits and only one carried the information.

Blatt is also considered a successful promoter of young scientists. Six of his assistants ( Christoph Becher , Jürgen Eschner , Hartmut Häffner , Dietrich Leibfried , Piet O. Schmidt , Ferdinand Schmidt-Kaler ) have now been appointed to professorships abroad.

Awards

Rainer Blatt received an honorary doctorate from the Complutense University of Madrid in 2020 . In 2019 he was honored with the Micius Quantum Foundation ( Micius Prize ). In 2016 he was awarded the International Quantum Communication Award . 2015 he was awarded the of the University of Toronto awarded John Stewart Bell awarded prize. In 2014 he received the Tyrolean State Prize for Science , in 2013 the Decoration of Honor of the State of Tyrol and a Humboldt Research Prize from the Alexander von Humboldt Foundation . In 2012 he was awarded the Stern-Gerlach Medal for work in quantum computer research, including the generation of a quantum byte and the transmission of quantum information. In 2011 he received the science award for extraordinary research achievements from the Südtiroler Sparkasse Foundation . Together with Ignacio Cirac, he was awarded the Carl Zeiss Research Prize in 2009. In 2008, Blatt received an “ERC Advanced Grant” from the European Research Council and was honored with the Cardinal Innitzer Prize . Together with his European project partners, he was nominated by the European Commission for the Descartes Prize in 2007. In 2006 he received the Erwin Schrödinger Prize from the Austrian Academy of Sciences. In 1997 he was awarded the Tiroler Sparkasse Innovation Prize for new ideas on quantum information processing .

Rainer Blatt has been a real member of the Austrian Academy of Sciences since 2008 and a member of the Austrian Science Council since 2010 . In 2000 he became a Fellow of the American Physical Society , in 2019 a foreign member of the National Academy of Sciences and in 2020 a foreign member of the Royal Academy of Exact, Physical and Natural Sciences in Spain.
