Whether it’s left there or right here… the tactics and destination look pretty much the same to me…

A future ‘quantum internet’ could find use long before it reaches technological maturity, a team of physicists predicts.
Such a network, which exploits the unique effects of quantum physics, would be fundamentally different to the classical Internet we use today, and research groups worldwide are already working on its early stages of development. The first stages promise virtually unbreakable privacy and security in communications; a more mature network could include a range of applications for science and beyond that aren’t possible with classical systems, including quantum sensors that can detect gravitational waves.
UK-based Crypto Quantique has announced the launch of what is being claimed as the world’s most advanced security product for IoT devices – with a quantum edge.
The technology behind this solution includes world’s first quantum driven secure chip (QDSC) on silicon which, when combined with cryptographic APIs, provides highly scalable, easy-to-implement and seamless end-to-end security for any connected device.
Quantum computing differs from classical computing in that it has the potential to find patterns and insights based on data which does not exist, rather than finding patterns in vast amounts of existing data. Its potential applications include improving security through quantum physics and enhancements to machine learning and artificial intelligence.
WASHINGTON — The U.S. Air Force announced on Wednesday it is awarding three contracts collectively worth about $2 billion to Blue Origin, Northrop Grumman Innovation Systems and United Launch Alliance to develop launch system prototypes.
The funding is for the development of competing launch system prototypes geared toward launching national security payloads. Each company will receive an initial award of $181 million.
The Launch Service Agreements are for the development of Blue Origin’s New Glenn, Northrop Grumman’s Omega and ULA’s Vulcan Centaur rockets. The awards are part of cost-sharing arrangements — known as Other Transaction Agreements — that the Air Force is signing with the three companies to ensure it has multiple competitors. The Air Force has committed through 2024 a total of $500 million in OTA funds for Blue Origin, $792 million for Northrop Grumman and $967 million for ULA. SpaceX previously received an LSA award but did not make the cut this time.
Optical frequency combs can enable ultrafast processes in physics, biology, and chemistry, as well as improve communication and navigation, medical testing, and security. The Nobel Prize in Physics 2005 was awarded to the developers of laser-based precision spectroscopy, including the optical frequency comb technique, and microresonator combs have become an intense focus of research over the past decade.
A major challenge has been how to make such comb sources smaller and more robust and portable. In the past 10 years, major advances have been made in the use of monolithic, chip-based microresonators to produce such combs. While the microresonators generating the frequency combs are tiny—smaller than a human hair—they have always relied on external lasers that are often much larger, expensive, and power-hungry.
Researchers at Columbia Engineering announced today in Nature that they have built a Kerr frequency comb generator that, for the first time, integrates the laser together with the microresonator, significantly shrinking the system’s size and power requirements. They designed the laser so that half of the laser cavity is based on a semiconductor waveguide section with high optical gain, while the other half is based on waveguides, made of silicon nitride, a very low-loss material. Their results showed that they no longer need to connect separate devices in the lab using fiber—they can now integrate it all on photonic chips that are compact and energy efficient.
A few factors were taken into consideration. These included security conditions, climatic conditions at that time of year, the existence of potential scientific partners, and what facilities were available.
Senegal has made great strides in astronomy and planetary sciences in recent years. That’s been largely driven by the Senegalese Association for the Promotion of Astronomy, led by Maram Kaire. Some Senegalese researchers are also involved in the African Initiative for Planetary and Space Sciences, which I head up.
And so, NASA focused its efforts in Senegal. It sent 21 teams to the country, and six to Columbia, which had less favorable climatic conditions. One team, composed of Algerian astronomers from the Centre de Recherche en Astrophysique et Géophysique, also attempted to observe the occultation in the south of Algeria.
A career’s worth of intelligence work for the U.S. Government has taught me one key lesson: national security is a lot like playing a game of chess. You have to anticipate your opponent’s every move in order to remain one step ahead.
Disclosing your strategy will be used against you. But if you recognize certain opportunities, you can win the match.
When I headed the government’s highly sensitive Advanced Aerospace Threat Identification Program (AATIP), I worked with a team to assess whether a particular chess piece — in this case in the form of an unfamiliar aerial technology — was a threat to our side of the chess board.
