Quantum gates of two silicon electrons. Two nano-electrodes (VL and VR) control the angular momentum of both electrons. A third nano-electrode (VM) coordinates the interaction of both electrons.

Stable quantum bits

Physicists from Konstanz, Princeton and Maryland create a stable quantum gate as a basic element for the quantum computer

Sea urchin spines

Nature’s blueprint

Based on the nanostructure of the sea urchin spines, the research team Physical Chemistry at the University of Konstanz develops cement that is significantly more fracture-resistant.
