An international team headed up by Alexander Holleitner and Jonathan Finley, physicists at the Technical University of Munich (TUM), has succeeded in placing light sources in atomically thin material layers with an accuracy ...
Nanowires promise to make LEDs more colorful and solar cells more efficient, in addition to speeding up computers. That is, provided that the tiny semiconductors convert electric energy into light, and vice versa, at the ...
Entanglement is one of the main principles of quantum mechanics. Physicists from Professor Johannes Fink's research group at the Institute of Science and Technology Austria (IST Austria) have found a way to use a mechanical ...
At the chemical level, diamonds are no more than carbon atoms aligned in a precise, three-dimensional (3-D) crystal lattice. However, even a seemingly flawless diamond contains defects: spots in that lattice where a carbon ...
Atomtronics manipulates atoms much in the way that electronics manipulates electrons. It carries the promise of highly compact quantum devices which can measure incredibly small forces or tiny rotations. Such devices might ...
In "Avengers: Endgame," Tony Stark warned Scott Lang that sending him into the quantum realm and bringing him back would be a "billion-to-one cosmic fluke."
Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of light to detect biological, ...
At the moment, sensitive data is typically encrypted and then sent across fiber-optic cables and other channels together with the digital "keys" needed to decode the information. However, the data can be vulnerable to hackers.
Information theory, which was developed by Claude Shannon starting in the late 1940s, deals with questions such as how quickly information can be sent over a noisy communications channel. Both the information carriers (e.g., ...
Most people are familiar with optical lasers through their experience with laser pointers. But what about a laser made from sound waves?
