High-temperature superconductivity induced in a semiconductor with Scotch tape

An international team has developed a simple new technique using Scotch poster tape that has enabled them to induce high-temperature superconductivity in a semiconductor for the first time. The method paves the way for novel new devices that could be used in quantum computing and to improve energy efficiency.

Physicists devise means for observing single atom interference over coherence length

(Phys.org)—Researchers at Sandia National Laboratories in Albuquerque, New Mexico have succeeded in observing the interference of a single atom over a distance far greater than its coherence length using lasers and sequences of light pulses. As they describe in their paper they've uploaded to the preprint server arXiv, it's the first ever such direct observance and opens the door to offering evidence of the existence of non-Newtonian gravity at the micron scale.

Electron magnetic moment calculated precisely

(Phys.org)—An electron, as well as other subatomic particles with an electric charge, is actually a little magnet—it spins like a top, giving it its own magnetic moment.

Light-based computers? First all-optical nanowire switch

Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1s and 0s were represented by light, instead of electricity. Researchers have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.
