Light switched on and off with few photons
CORNELL (US) — The passage of a light beam through an optical fiber can be controlled by just a few photons of another light beam, new research demonstrates. Continue…

Tiniest gold has strength of Goliath
U. BUFFALO (US) — At an atomic scale, the narrowest bridge of gold, made of a single atom, is paradoxically the strongest, according to new research. (more…)

Nanowriting a big step in electronics
U. ILLINOIS (US) — A method for direct writing of metal lines less than five nanometers wide is expected to have a big impact in creating contacts to and interconnects between nanoscale device structures. (more…)

How to create something from nothing
U. MICHIGAN (US) — Under just the right conditions—which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator—it could be possible to generate matter and antimatter from a vacuum. (more…)

One step closer to quantum computing
PRINCETON (US)—Physicist Jason Petta may have overcome a major hurdle to designing and constructing a radically new kind of quantum computer. He’s figured out how to manipulate the single electrons that very likely will constitute the new machines’ processing components or “qubits.” (more…)

The photon force is with us—and it’s driving our nanomachines
YALE (US)—Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun’s light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines—when the process is scaled to nano-proportions.
