Scientists Paint Quantum Electronics With Beams Of Light

A team of scientists from the University of Chicago and the Pennsylvania State University have accidentally discovered a new way of using light to draw and erase quantum-mechanical circuits in a unique class of materials called topological insulators. In contrast to using advanced nanofabrication facilities based on chemical processing of materials, this flexible technique allows […]

Perfectly Accurate Clocks Turn Out To Be Impossible

Can the passage of time be measured precisely, always and everywhere? The answer will upset many watchmakers. A team of physicists from the universities of Warsaw and Nottingham have just shown that when we are dealing with very large accelerations, no clock will actually be able to show the real passage of time, known as […]

Electron Orbitals of Molecules Measured in 3D

You might remember them from your physics lessons at school: often represented as colourful clouds or balloons, electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists from the University of Graz, Forschungszentrum J├╝lich, and the Physikalisch-Technische Bundesanstalt have now succeeded in experimentally recording these structures in all three dimensions. […]

Quantum Crypotography: New Diamond Structures Produce Bright Luminescence

New research shows that germanium defects in a diamond crystal lattice act as a reliable source for single photons. The results provide a promising new route to building components for quantum cryptography and biomarkers. Pure diamonds are naturally colorless, but gaps in the crystal structure or impurities of other elements can create colors and even […]
