QUROPE Quantum Information Processing and Communication in Europe

The round table is organized during the ICAP 2012 conference, and is one of the highlights of several special events. This public event is sponsored by the 'Quantum Envoy' program of the Coordination Action QUIE2T.

Quantum computers, should they be realized one day, will inevitably make errors. Therefore, they need special error correcting mechanisms. The most important part of it, a so-called Toffoli gate, has now been realized by ETH scientists with superconducting circuits. 

Der diesjährige Max-Rössler-Preisträger, der Physiker Andreas Wallraff, forscht mit dem Ziel quantenmechanische Maschinen zu bauen. Der Max-Rössler-Preis ist der höchst dotierte Forscherpreis der ETH Zürich und wurde 2007 durch eine Donation an den «Strategischen Fonds» der ETH Zürich Foundation ins Leben gerufen. 

Der ETH-Physiker Andreas Wallraff entwickelt Mikrochips, die tausendmal energieeffizienter sind als herkömmliche Computer.

Photons in the microwave frequency range are important in quantum research - for quantum information processors, for example. Now, for the first time, researchers have achieved the controlled production of single photons in the microwave region and successfully detected them with highly sensitive measuring instruments - although they are 100,000 times weaker than the photons emitted by an electric light bulb. 

Thirty-three Swiss research groups have joined the National Centre of Competence in Research "Quantum Science and Technology" (QSIT) with the aim of exploring the boundaries between classical and quantum mechanics, and combining different research approaches. The researchers are not just hoping for success with regard to a quantum computer. The leading house is ETH Zurich with Director Klaus Ensslin, a professor of experimental physics. 

Evidence for elusive Majorana fermions raises possibilities for quantum computers.
