Use of laser light yields versatile manipulation of a quantum bit

By using light, researchers have manipulated the quantum state of a single atomic-sized defect in diamond -- the nitrogen-vacancy center -- in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems.

Best of both worlds: Towards a quantum internet with combined optical and electrical technique

Scientists have achieved a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers -- connected via a quantum internet -- closer to reality. The team is the first to have detected the spin, or quantum state, of a single atom using a combined optical and electrical approach.

X-rays paint a picture of Picasso's pigments

(Phys.org) —Pablo Picasso is widely regarded as one of the most influential artists of the twentieth century, having pioneered a variety of new styles in painting, sculpture, and other artistic forms. Besides introducing avant-garde art styles, he also innovated in the use of non-traditional materials. For example, a widely-held view has been that Picasso employed the ordinary house paint Ripolin in place of conventional artists' paints in some of his artwork.

Researchers tackle collapsing bridges with new technology

In this month's issue of Physics World, an international group of researchers propose a new technology that could divert vibrations away from load-bearing elements of bridges to avoid catastrophic collapses.
