Unlike classical encryption, which relies on mathematical algorithms, quantum encryption assures security based on physical principles. Detection of espionage or interference is guaranteed by unavoidable alteration of the quantum states involved.
A very dangerous position to be in the world community of scientist should gather in agreement those friendly to the values and principles of democracy to advance science for the good humanity and freedom.
The U.S. sorely needs a coordinated national research strategy, says Marcia McNutt, president of the U.S. National Academy of Sciences.
Researchers uncover 10 security flaws in Google’s Quick Share, potentially allowing remote code execution on Windows. Update to version 1.0.1724.0 or.
Startup Riverlane helped continue what has been a strong year for venture funding in the quantum computing industry.
The U.K.-based firm — which specializes in quantum error correction technology — raised a $75 million Series C led by Planet First Partners. The round also includes participation from ETF Partners, EDBI, Cambridge Innovation Capital, Amadeus Capital Partners, the National Security Strategic Investment Fund and Altair
The company’s tech helps quantum computers perform without succumbing to eventual errors. Such computers typically can only perform a few hundred quantum operations before failure.
Artistic representation of hyper-Raman optical activity: twisted light (red helices) incident on molecules arranged on a helical scaffold (white dots) produce hyper-Raman scattering spectra (multicoloured light patches) that express ‘chirality’ (patches in spiral patterns and broken mirror). Credit: Ventsislav Valev and Kylian ValevAn international team of scientists, led by physicists from the University of Bath, has demonstrated a new optical phenomenon that could significantly impact various fields, including pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.
Molecules rotate and vibrate in very specific ways. When light shines on them it bounces and scatters. For every million light particles (photons), a single one changes colour. This change is the Raman effect. Collecting many of these color-changing photons paints a picture of the energy states of molecules and identifies them.
Yet some molecular features (energy states) are invisible to the Raman effect. To reveal them and paint a more complete picture, ‘hyper-Raman’ is needed.
Microwave technology has dramatically progressed, marked by the arrival of the 5G era, owing to the advantages of electromagnetic waves in long-distance, wireless, and high-speed transmissions. However, electromagnetic wave pollution problems such as electromagnetic wave interference and electromagnetic wave radiation are becoming increasingly serious.
Electromagnetic wave pollution not only affects the normal operation of electronic equipment, greatly threatens the information security of the scientific community, but also endangers human health and is a possible cause of cancer and sensitized diseases.
SiOC precursor ceramics have great application potential in electromagnetic protection because of their advantages such as lightweight, high-temperature resistance, and molecular designability. The main challenge of polymer-derived ceramic-based composites for electromagnetic wave absorption is the single loss mechanism, resulting in inferior electromagnetic wave attenuation ability.
Passwords, Touch ID, and Face ID could all be a thing of the past, as Apple is working on a future where unlocking your devices is as easy as just holding a future iPhone or letting your Apple Watch sense your unique heart rhythm.
Everyone’s heart has a unique rhythm, which the Apple Watch monitors through the ECG app. In a recently granted patent, Apple describes a technique for identifying users based on their unique cardiovascular measurements.
With this technology, you can unlock all your devices if you keep wearing your Apple Watch. Verifying your heart patterns instead of a password or a fingerprint scan increases security and speeds up your identification.
A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact on pharmaceutical science, security, forensics, environmental science, art conservation and medicine.
The plan would be to launch Starship from a SpaceX facility in Texas, land it in the sea off Australia’s coast and recover it on Australian territory. Getting permission to do so would require loosening US export controls on sophisticated space technologies bound for Australia, according to the sources, who spoke on condition of anonymity.
President Joe Biden’s administration already has sought to ease similar restrictions within the AUKUS security alliance, opens new tab, a grouping of the United States, Australia and Britain aimed at countering China.
SpaceX, the US Space Force and the Australian Space Agency did not immediately reply to requests for comment.
