Credit: CC0 Public Domain Quantum engineers from UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing. In a paper published today in Nature Communications, UNSW quantum computing researchers describe how they created artificial atoms in a silicon ‘quantum dot’, a tiny space in a quantum circuit where electrons

Credit: HZB High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in a zero field. Usually, high fields exceeding a certain critical value force the moments to align in the same direction as the field, leading to ferromagnetic arrangement. However, a recent study showed that

The measurement setup for the characterization of microbridges in a cryostat. Credit: Martin Wolff The development of a quantum computer that can solve problems, which classical computers can only solve with great effort or not at all—this is the goal currently being pursued by an ever-growing number of research teams worldwide. The reason: Quantum effects,

Terahertz radiation can be used for many kinds of imaging, such as in airports or in nondestructive materials testing. A new technique uses it for high-speed video. Credit: Sequestim/Cardiff University A team of researchers at Durham University has found a way to use long-wavelength terahertz radiation to produce video with a high frame rate. In

Experiments at SLAC showed that an inexpensive photosensitizer molecule, iron carbene, can respond in two competing ways when hit by light. Only one of those pathways (right) allows electrons to flow into devices or chemical reactions where they’re needed. The molecules took this energy-producing path about 60% of the time.

Credit: CC0 Public Domain Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated successfully in any experiment—until now. “This ‘backflow’ phenomenon is quite delicate and requires exquisite control over the
