Physiker haben in einem neuartigen Ansatz gezeigt, wie die Ausbreitungsrichtung von Licht bzw. Lichtenergie auf der Ebene einzelner Molekuele manipuliert werden kann. Dazu platzierten die Biophysiker eine Kaskade von vier verschiedenen Fluoreszenz-Farbstoffmolekuelen auf einer DNA-Plattform im Nanometer-Massstab. Mithilfe eines sogenannten "Springer"-Farbstoffs gelang es ihnen, die Richtung des Lichtweges bzw. des Energietransfers zu kontrollieren.

Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.
