BREAKTHROUGH IN QUANTUM STORAGE OF ENTANGLED PHOTONS MAY USHER AGE OF SOLID STATE-BASED QUANTUM NETWORKS

Chinese researchers report the successful quantum storage of entangled photons at telecom wavelengths within a crystal, in a breakthrough achievement that reportedly lasted 387 times longer than past similar experiments.

The research team, based at Nanjing University, says their findings could potentially “pave the way for realizing quantum networks based on solid-state devices.”

Experts have differing opinions on how soon we may see a global quantum internet. However, no one disputes that once it is achieved, it will revolutionize how information is processed and secured. In the move toward that reality, researchers are currently focusing on ensuring that processes that include quantum storage and distribution of entangled photons will be compatible with existing telecommunications networks.

In the case of entangled photons, entanglement describes the quantum phenomenon where particles remain connected, which effectively allows actions performed on one to affect its entangled counterpart even from across great physical distances.

However, making sure that quantum networks work reliably using fiber-based systems, like those the Internet currently uses, presents a number of challenges, namely signal loss due to the limitations of optical fiber systems that are presently in use.

One way of overcoming these problems involves the use of devices called quantum repeaters, which can help extend the range of these systems by storing the quantum state of photons into matter. Successful quantum repeaters must accomplish three primary tasks: 1) they must match the standard telecom wavelength, which is around 1.55 μm; 2) they must be capable of storing data for long periods; and 3) they have to be able to handle multiple data streams simultaneously.

Cartel Narco Tank With Cope Cage Anti-Drone Armor Emerges

AMexican drug cartel recently employed an improvised armored truck, also commonly referred to as a “Narco Tank,” with what looks to be a metal screen over the front section of the vehicle. This is reminiscent of the so-called “cope cages” that have become a fixture on tanks and other armored vehicles on both sides of the conflict in Ukraine and that have also now emerged on Israeli tanks. These screens are primarily intended to provide extra protection against drones, something that cartels in Mexico are now regularly employing against government security forces and each other.

The Mexican vehicle in question was a modified Dodge Ram truck with a four-door cab that also had a box-like improvised armored structure at the rear with ports through which individuals inside could fire small arms. It was one of three Narco Tanks that took part in an ambush of Mexican military forces in the country’s state of Jalisco just over a week ago. The Cártel de Jalisco Nueva Generación (CJNG), or Jalisco New Generation Cartel, carried out the attack on November 19, which also reportedly involved the rapid establishment of roadblocks to hamper the arrival of government reinforcements.

NASA TO LAUNCH STADIUM-SIZED CRAFT OVER ANTARCTICA IN NEW MISSION TO EXPLORE COSMIC PHENOMENA

A long-duration aerial mission soon to be carried out by NASA over Antarctica will launch stadium-sized craft in support of a series of record-breaking science missions, the agency announced this week.

The Antarctic Long Duration Balloon (LDB) Campaign, which includes a trio of scientific balloon flights equipped to study a range of different phenomena, will launch at the beginning of December, according to a press release NASA issued on Monday.

The mission will employ a series of massive zero-pressure balloons, which the American space agency says will support five missions in total.

Equipped with open ducts through which gas can escape, thereby eliminating the buildup of pressure within, zero-pressure balloons expand as they accumulate heat from the rising Sun as they are being carried aloft. Conversely, as the Sun sets, heat is lost, which results in a loss of gas, which causes zero-pressure balloons to have a shorter flight duration than other inflatable systems.

However, long-duration missions can be achieved during the polar summer, a period during which the balloons remain in constant sunlight for extended periods.

One of the missions aims to break a previous long-duration balloon flight record of just over 55 days. The balloons will launch from NASA’s facility for balloon launches located close to McMurdo Station, the largest community on Earth’s southernmost continent located on the southern edge of Ross Island, Antarctica.

EXPLORING INFANT CONSCIOUSNESS DEVELOPMENT: NEW RESEARCH REVEALS BABIES LIKELY DEVELOP CONSCIOUSNESS IN THE WOMB

Recent scientific advances are bringing us closer to understanding infant consciousness development and answering a question that has puzzled scientists, parents, and philosophers alike for centuries: when does consciousness begin? 

In a new study published in the peer-reviewed journal Trends in Cognitive Science, an international team of researchers says empirical evidence suggests infants possess consciousness before birth, by at least the third trimester of pregnancy. 

Researchers say the findings and pinpointing the moment when consciousness first appears could have significant clinical, ethical, and legal implications. 

Historically, the question of when consciousness first emerges has been a topic of much speculation and debate. 

It is generally accepted that the growing human fetus lacks the neural cells required for consciousness during the first trimester of pregnancy. However, traditional viewpoints differ widely on when consciousness first emerges. 

Some recent studies have proposed that consciousness emerges 24-26 weeks after conception when thalamocortical connections activate the neural cortex. 

Others have argued that infants lack the higher-order thought necessary for self-awareness until around the first birthday or even later. 

In this recent study, a team of neuroscientists and philosophers from Monash University, the University of Tübingen, the University of Minnesota, and Trinity College Dublin conducted a meta-analysis of the latest empirical findings and methodological advancements in infant consciousness development research. 

A vital component of the meta-analysis was accepting the complex nature of consciousness as a subjective phenomenon characterized by a unique experiential point of view.

Unlike adults and older children, infants cannot verbalize their experiences. Instead, researchers had to rely on indirect markers to gauge the presence of consciousness. These markers include behavioral responses, neural activities, and developmental milestones.

Examining these indirect markers, researchers found that several lines of evidence pointed to the early emergence of consciousness. 

One key piece of evidence was the development of intrinsic connectivity networks in the brain, such as the default mode network (DMN), which are active early in development.

These networks, typically associated with higher cognitive functions, are present in newborns and preterm infants, suggesting the early onset of consciousness.

Researchers also examined the role of attention in consciousness development. It’s generally understood that top-down (voluntary) attention develops around 3 to 6 months of age, while bottom-up (involuntary) attention is evident from birth. This distinction is crucial as it indicates that the emergence of consciousness might be linked to the development of attentional capabilities.

Another intriguing line of evidence came from the study of multisensory integration in infants. Certain complex forms of multisensory integration, thought to occur only when stimuli are consciously perceived, have been observed in infants as young as four months. This further supports the early-onset theory of consciousness.

NewsGuard Is Selling Its Government-Funded Censorship Tool To Private Companies

The for-profit censorship giant NewsGuard is now selling its “Misinformation Fingerprints” technology to private companies to silence Americans’ speech — technology the federal government helped NewsGuard develop to the tune of nearly $750,000 in taxpayer funding. So while NewsGuard is now making headlines for trying to take down Elon Musk’s X, the bigger story concerns the federal government’s funding of the censorship-industrial complex.

NewsGuard launched a Thanksgiving-week attack on the social media company former known as Twitter, claiming some 200 ads from prominent advertisers appeared on feeds of users spreading lies about the Israel-Hamas war. Elon Musk returned fire, calling NewsGuard “a propaganda shop” that “uses these reports to pressure companies to buy their ‘fact-checking’ services.”

“It’s a profit over any principle model,” the X owner countered.

The verbal sparring between Musk and NewsGuard is likely to continue for some time, but the war on free speech being waged by NewsGuard extends much beyond X and is being subsidized by our tax dollars.

“In September 2021, NewsGuard was awarded a grant through the Small Business Innovation and Research program, which funds early-stage companies to develop products and technologies that can be helpful for government,” NewsGuard announced in its 2021 Social Impact Report. “Under the grant,” the report explained, “NewsGuard plans to further develop the Misinformation Fingerprints tool and test the effectiveness of the Fingerprints in detecting state-sponsored disinformation campaigns.”

Federal records show the Department of Defense funded the Small Business Innovation and Research program’s award of nearly $750,000 to NewsGuard for the further development and testing of the Misinformation Fingerprints tool. And according to NewsGuard’s 2021 Social Impact Report, its “Misinformation Fingerprints” catalog traced “762 false narratives,” “providing one-of-a-kind tracking seeds for the AI tools used by defense industry clients.”

By the following year, NewsGuard reported in its 2022 Social Impact Report that its “Misinformation Fingerprints” technology had accumulated 1,122 supposedly false narratives and been “deployed at scale” — including by social media companies. Since then, NewsGuard has highlighted the use of the Misinformation Fingerprints tool by social media companies “seeking to mitigate falsehoods on their platforms…”

Israeli ‘Iron Beam’ Lasers Are ‘Future Of Warfare’

Last year we reported on Israel’s development of a ground-based laser defense system dubbed ‘Iron Beam,’ which then-Prime Minister Naftali Bennett called “a game-changer” that could “bankrupt” the enemy.

Now, it’s being reported that the system – which has been in development by Rafael Advanced Defense Systems for 15 years, and was originally set for a 2025 rollout, will be deployed more quickly than that due to the Israel-Hamas war, and it may be placed in service as early as 2024.

More than a hundred Rafael engineers have reportedly been working on this project, considered one of the most significant technological challenges ever faced by the Israeli defense industries, in order to create a fast and effective interception system, with inexhaustible and near cost-free ammunition.

Recent tests of Iron Beam in the Negev have shown promising results, with the system successfully intercepting various airborne threats. The heart of the system is an electric laser pointer, capable of targeting and sending out a powerful laser beam, invisible to the naked eye.

Since the war erupted on October 7, more than 10,000 projectiles have been fired at Israel, including 3,000 in the first hours of the conflict. Rafael and the Israeli Defense Ministry have considered the current operations as an opportunity to test the Iron Beam under real combat conditions. –i24news

Speaking with Calcalist, one of Rafael’s iron beam program managers expressed high hopes for the system, saying “Our aim is to reach a state where the enemy feels totally powerless. He has to understand that our laser pointers, deployed where needed, intercept and destroy all his attacks, almost instantly after they are launched, long before they reach Israeli territory or threaten anyone else. In such a scenario, the activation of warning sirens might even become unnecessary.”

THESE ARE THE TOP FOUR THEORIES THAT COULD BRING US CLOSER TO FASTER-THAN-LIGHT TRAVEL

Since Captain Kirk first ordered the Starship Enterprise to engage the warp drive back in 1967, fans of science fiction have dreamed of traveling to the stars at warp speed. That idea remained in the realm of science fiction until 1994, when Mexican mathematician Miguel Alcubierre proposed a mathematically viable solution for building a real-world faster-than-light warp drive.

Since then, numerous scientists and engineers have taken a swing at their own version of a viable, real-world warp drive, including an attempt to patent one of these “out there” ideas.

Here, The Debrief looks at three of the past most promising warp drive models, along with one brand new physics concept called the “Tri-Space Model,” which may hold the key to making faster-than-light travel possible.

EERIE GLOWS AND ELECTRON BEAMS: WHAT WERE NASA’S ‘DISSIPATION’ AND ‘BEAM-PIE’ MISSIONS INVESTIGATING OVER REMOTE ALASKA?

On Wednesday, NASA launched a sounding rocket into the early morning skies above Fairbanks, as the wavering green glow of the aurora borealis danced over the Poker Flat Research Range near Mile 30 along Alaska’s Steese Highway.

The Wednesday launch was part of NASA’s DISSIPATION mission, managed out of Goddard Space Flight Center, which aims to capture data that will help scientists understand phenomena associated with auroras, including how high-altitude solar winds dissipate their energy, and how auroras contribute to heating the atmosphere, according to a NASA statement.

Part of the mission’s focus involves a region between 60 and 180 miles over the Earth and at latitudes above 65 degrees, known as the high-latitude ionosphere-thermosphere, where energy from charged solar wind particles is dissipated.

Researchers involved said that the launch, which occurred shortly after midnight, was timed perfectly with the peak of the aurora that morning, which lasted less than half an hour.

The Pentagon is moving toward letting AI weapons autonomously decide to kill humans

The deployment of AI-controlled drones that can make autonomous decisions about whether to kill human targets is moving closer to reality, The New York Times reported.

Lethal autonomous weapons, that can select targets using AI, are being developed by countries including the US, China, and Israel.

The use of the so-called “killer robots” would mark a disturbing development, say critics, handing life and death battlefield decisions to machines with no human input.

Several governments are lobbying the UN for a binding resolution restricting the use of AI killer drones, but the US is among a group of nations — which also includes Russia, Australia, and Israel — who are resisting any such move, favoring a non-binding resolution instead, The Times reported.

“This is really one of the most significant inflection points for humanity,” Alexander Kmentt, Austria’s chief negotiator on the issue, told The Times. “What’s the role of human beings in the use of force — it’s an absolutely fundamental security issue, a legal issue and an ethical issue.”

The Pentagon is working toward deploying swarms of thousands of AI-enabled drones, according to a notice published earlier this year.

In a speech in August, US Deputy Secretary of Defense, Kathleen Hicks, said technology like AI-controlled drone swarms would enable the US to offset China’s People’s Liberation Army’s (PLA) numerical advantage in weapons and people.

“We’ll counter the PLA’s mass with mass of our own, but ours will be harder to plan for, harder to hit, harder to beat,” she said, reported Reuters.

Frank Kendall, the Air Force secretary, told The Times that AI drones will need to have the capability to make lethal decisions while under human supervision.

OpenAI researchers warned board of AI breakthrough ahead of CEO ouster, sources say

Ahead of OpenAI CEO Sam Altman’s four days in exile, several staff researchers wrote a letter to the board of directors warning of a powerful artificial intelligence discovery that they said could threaten humanity, two people familiar with the matter told Reuters.

The previously unreported letter and AI algorithm were key developments before the board’s ouster of Altman, the poster child of generative AI, the two sources said. Prior to his triumphant return late Tuesday, more than 700 employees had threatened to quit and join backer Microsoft (MSFT.O) in solidarity with their fired leader.

The sources cited the letter as one factor among a longer list of grievances by the board leading to Altman’s firing, among which were concerns over commercializing advances before understanding the consequences. Reuters was unable to review a copy of the letter. The staff who wrote the letter did not respond to requests for comment.

After being contacted by Reuters, OpenAI, which declined to comment, acknowledged in an internal message to staffers a project called Q* and a letter to the board before the weekend’s events, one of the people said. An OpenAI spokesperson said that the message, sent by long-time executive Mira Murati, alerted staff to certain media stories without commenting on their accuracy.

Some at OpenAI believe Q* (pronounced Q-Star) could be a breakthrough in the startup’s search for what’s known as artificial general intelligence (AGI), one of the people told Reuters. OpenAI defines AGI as autonomous systems that surpass humans in most economically valuable tasks.

Given vast computing resources, the new model was able to solve certain mathematical problems, the person said on condition of anonymity because the individual was not authorized to speak on behalf of the company. Though only performing math on the level of grade-school students, acing such tests made researchers very optimistic about Q*’s future success, the source said.

Reuters could not independently verify the capabilities of Q* claimed by the researchers.
