In the first decades of the 20th century, physicists hotly debated how to make sense of the strange phenomena of quantum mechanics, such as the tendency of subatomic particles to behave like both particles and waves. One early theory, called pilot-wave theory, proposed that moving particles are borne along on some type of quantum wave, like driftwood on the tide.
When the military needs to send the key to encrypted data across the world, it can't necessarily rely on today's communication lines, where the message could be covertly intercepted.
But physicists at the Geor...
The long-held dream of creating atomically precise three-dimensional structures in a manufacturing environment is approaching reality, according to the top scientist at a company making tools aimed at that ambitious goal...
Photonic crystals are exotic materials with the ability to guide light beams through confined spaces and could be vital components of low-power computer chips that use light instead of electricity.
Eulitha AG, a Swiss based nanolithography company, has developed a proprietary photolithography technology for low-cost and high-throughput fabrication of photonic nanostructures. This solves a major ongoing problem faced in the fabrication of high-resolution photonic structures using standard photolithography equipment.
Zecotek Photonics Inc. (TSX VENTURE:ZMS)(FRANKFURT:W1I), a developer of leading-edge photonics technologies for medical, industrial and scientific markets, today announced it has appointed Dr. Jalil Ali to its Board of Directors.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated for the first time the conversion of near-infrared 1,300 nm wavelength single photons emitted from a true quantum source, a semiconductor quantum dot, to a near-visible wavelength of 710 nm.
Physicists at UC Santa Barbara have succeeded in combining laser light with trapped electrons to detect and control the electrons' fragile quantum state without erasing it. This is an important step toward using quan...
Scientists at JILA and collaborators have demonstrated an improved laser-based "molecular fingerprinting" technique that picks out traces of key hydrogen-containing and other molecules from a billion other particles in a gas in just 30 seconds or less—performance suitable for breathalyzers for diagnosing disease, measuring trace gases in the atmosphere, detecting security threats and other applications.
A new source of ions will soon be the starting point for the beams entering two major research facilities at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory — the Relativistic Heavy Ion Collider (RHIC), where physicists are recreating conditions of the early universe to learn more about the forces that hold matter together, and the NASA Space Radiation Laboratory (NSRL), where scientists study the effects of space radiation to help find ways to protect astronauts.
