Revolutionary Quantum Funds Stored on Ultra-Cold ‘Debit Card’

Quantum Debit Card Ensures Financial Security

New quantum debit cards, which can hold unforgeable quantum funds, are constructed using extremely cooled atoms and light particles.

While standard banks often rely on the skill of counterfeiters to detect fake banknotes, quantum banks utilize the no-cloning theorem from physics, rendering counterfeiting impossible. This principle, which states that creating identical copies of quantum information is not feasible, led physicist Stephen Wiessner to propose a protocol in 1983 for generating secure currencies. Julian Laurat and his team at the Kastler Brossel Laboratory in France are actively implementing this groundbreaking concept in advanced experiments.

According to this protocol, banks create banknotes composed of quantum particles, possessing unique properties and existing in specific quantum states, thus ensuring protection against forgery through the no-cloning theorem. Laurat remarks that the protocol showcases an impressive feat of quantum cryptography, though it has not yet been put into practice for actual quantum fund storage.

The research team has made storage feasible by combining memory devices with hard drives. In their experiments, users interact with quantum systems that act as banks by exchanging photons. Each photon can be stored similarly to loading money onto a debit card.

The memory devices used by the team consist of hundreds of millions of cesium atoms, which researchers cool down to nearly absolute zero by bombarding them with lasers. At such extreme temperatures, light can precisely manipulate the quantum state of atoms, but Laurat notes that years were spent identifying the optimal cooling needed for atomic memory to serve as a quantum debit card. Through extensive testing, he and his colleagues demonstrated that users can retrieve photons from atoms without corrupting their states, as long as the process is not tampered with.

Christophe Simon from the University of Calgary emphasizes that the new experiment marks progress toward fully realizing quantum funding. However, the current quantum memory storage time of around six million seconds remains insufficient for practical application. “Another future step is to enhance portability. The long-term goal is to develop quantum memory that can be easily carried, particularly for Quantum Money applications. But we are not there yet,” he states.

The team is focused on extending storage durations, asserting that the protocol can be employed within quantum networks already being established in metropolitan areas across the globe. Additionally, cutting-edge quantum memory not only facilitates ultra-secure long-distance quantum communication but is also instrumental in connecting various quantum computers to more powerful systems.

Palestinian Social Media Accounts Seeking Funds Flagged as Spam | Technology

Hanin Al-Batsh estimates that over the past six months, he has created more than 80 accounts on Bluesky.

Like many other Palestinians struggling to secure food in Gaza, Albatos hopes that Blue skiing will help her raise enough funds for flour and milk for her children as part of her crowdfunding efforts.

She shared that posting to text-based social networks has become even more critical as Israel tightens its hold on Gaza, leading to widespread starvation.

“Hello, my kids are getting weaker, losing weight, and suffering from malnutrition and low iron levels,” said Al-Batsh in her most recent post.


Images shared with The Guardian by the young mother reveal her two sons, Ahmed, aged 1.5, and Adam, who is three, lying on a makeshift bed on the floor of the warehouse where they are taking shelter.

As hunger proliferates across Gaza and aid remains scarce, Palestinians are increasingly looking to crowdfunding platforms like Gofundme and Chuffed as their lifelines.

However, their attempts to promote their campaigns on social media often result in their accounts being shut down or flagged as spam, particularly on Bluesky, the emerging alternative to Twitter in Gaza.

According to her, Bluesky deactivated almost all of Al-Batsh’s accounts just days later, with the longest one remaining active for only 12 days.

When a social network such as Bluesky flags an account as spam, she feels compelled to establish a new account, reassuring potential donors that she is not a bot.

To combat bots and fraud, the shutdowns ironically compel Blueski users to rely on tagging the same individuals who previously engaged with them in an attempt to counter bots and fraud.

Although Al-Batsh refrains from tagging individuals in every post after receiving strict instructions from Bluesky, she expresses frustration, stating, “Now no one can find my posts.”

Desperation drives many Palestinians to act like bots. With new accounts, it becomes increasingly challenging for individuals like Al-Batsh to refute accusations of being automated accounts; fewer followers and repetitive tagging can trigger suspicions.

Nevertheless, grassroots responses to the issue have emerged. Since May, Al-Batsh has started marking her posts with a green checkmark emoji and the phrase “verified by Molly Shah.”

A small group of volunteers assist her with similar tasks on Bluesky. Comparable initiatives are taking place across various social media platforms, with some run by larger teams of volunteers. X and Instagram have Gazafunds and Radio Watermelon, while Tumblr has Gaza Vetters.

Despite this, Shah expresses her desire for a more structured system, stating, “This is too much focus on me.”

Guerrilla Verification Network

Shah has been involved with Blueski since its early days.

Thus began her verification project. She encouraged her friend Jamal to set up a Bluesky account to share posts for her campaign, hoping to draw attention to it in 2023. Jamal managed to raise enough money to leave Gaza.

Shah’s verification project gained momentum as more individuals from Gaza joined the social network. Many reached out to her, hoping that she would share their campaigns with her substantial follower base of 57,000. She began vetting the individuals and families behind each campaign before sharing their information, paving the way for her guerrilla verification network.

Today, Shah maintains spreadsheets for over 300 accounts that she has verified. They use the same authentication badge as Al-Batsh, labeling their posts and profile pages with “Validated by Molly Shah.” While this stamp does not entirely prevent Bluesky’s system from flagging accounts as spam, she hopes it helps reassure users that the account owner is genuine.

“The validation appears to help people recognize that these are real individuals,” Shah stated. “My main goal is not to fundraise; it’s about combatting the ongoing and systemic dehumanization of Palestinians.”


Shah mentioned that the review process is not standardized and allows video calls. She accepts documents from people she has already vetted or knows personally to validate their identity and confirm their presence in Gaza. This process is time-consuming; Al-Batsh reported waiting two months for a response from Shah. Occasionally, Shah encounters individuals who falsely claim to be from Gaza or misrepresent their circumstances, but most are genuine people seeking assistance.

Crucial Fraud Prevention

According to aid and human rights organizations, Gaza is facing unprecedented levels of hunger, increasing the stakes for fundraising campaigns and amplifying the importance of every Bluesky post. Duaa al-Madoon, another mother in Gaza, recently shared her struggles to feed her three children and mentioned that she also deleted her Bluesky account. The cost of flour, milk, and diapers can reach $100 daily when available; recently, she has found it challenging to locate diapers and milk, going days without eating to ensure her children are fed.

“My child has no proper diaper, causing severe rashes. Food is scarce and exorbitantly priced. If you manage to get something, it’s mainly rice,” lamented Al-Madoon.

According to Nat Calhoun, who has supported several families in Gaza through a campaign, the impact of fundraising can be immediate. In one case, a family contacted them about an elderly woman in Mawasi who had not eaten for several days. They were able to raise $110 to supply her with flour and sent her the funds the next day.

“It can be instantaneous,” Calhoun noted. “I don’t think people realize how much their support can genuinely impact someone’s day.”

To receive funds raised through campaigns, Palestinians must collaborate with ‘recipients.’ Individuals outside Gaza initiate campaigns, collect funds on their behalf, and transfer money through banks because the payment processor used by the platform does not operate in Gaza.

This system necessitates that Palestinians place substantial trust in these intermediaries, individuals they have never met.

Consequently, campaigns and the Palestinians they aim to assist are vulnerable to fraud.

Calhoun and Shah noted that much of the fraud they encounter exploits vulnerable Palestinians.

Al-Batsh’s initial campaign on GoFundMe was organized by a woman who claimed to be located in Tucson, Arizona. The campaign raised almost $37,000, but Al-Batsh only received about $34,000 before the campaign organizer faced issues accessing her account. “I have never received the remaining funds,” Al-Batsh lamented.

“The thought of it is maddening,” said Calhoun. “Because the people of Gaza cannot fundraise independently. They are at the mercy of others and must trust that those people will treat them fairly.”

Requesting Changes from Bluesky

Bluesky’s spam filters often obstruct donations. Ad hoc verification systems like Shah’s provide a level of assurance that the funds donated are directed to legitimate individuals in Gaza rather than fraudulent entities.

When Shah shares a campaign, the difference is noticeable. Al-Batsh’s campaign garnered 10 donations ranging from $5 to $505 within just two days of her sharing it, compared to an average of two or three donations per day prior.

Although her validation network has helped some Palestinians maintain their online presence, Shah admits that it is not a sustainable solution. Overwhelmed by requests, she has limited her sharing to one account daily.

Meanwhile, thousands of Bluesky users have signed open letters urging the platform to enhance its moderation practices.

“We understand that when posting a fundraising link, Gazans may trigger Bluesky’s automated spam filters,” states an open letter signed by 7,000 individuals. “However, just as the platform addresses spam from T-shirt bots, failing to accommodate a vulnerable group is not only cruel but exacerbates their struggles for survival.”

Bluesky stated in response to the open letter that it is committed to ensuring that the voices of Gaza residents are heard on its platform. However, they noted that certain account activities violated community guidelines and urged users to focus their efforts through verified accounts.

Bluesky has not responded to requests for comment.

“We acknowledge that we may not always make the right moderation decisions, which is why we have an appeals process,” the statement continued. However, Shah and others advocating for Gaza residents say very few receive responses when filing appeals, making it challenging for Palestinians to maintain account access beyond a brief period.

Shah noted that Bluesky had an opportunity to improve its moderation systems in the early days of the conflict in Gaza when fewer users were on the platform. She hopes they seized that opportunity.

“It seems that Bluesky is saying, ‘we’re eliminating spammers,’ but it’s the very people we are striving to protect who are being targeted,” she concluded.

Europe Seeks to Attract Scientists Following Trump’s Freeze on U.S. Funds

On Monday, the European Union kicked off its initiative to draw scientists and researchers to Europe through grants and new policy proposals following the freezing of government funding related to diversity, equity, and inclusion by the Trump administration.

“A few years back, it would have seemed unimaginable that one of the world’s major democracies would terminate a research initiative simply because it included the word ‘diversity,'” stated French President Emmanuel Macron at the “Choose Science” event in Paris.

“No one would have believed it possible for a significant democracy to hinder a researcher’s chances of obtaining a visa,” Macron remarked. “Yet, here we are.”

Ursula von der Leyen, head of the European Commission, joined Macron at Sorbonne University, announcing a new “super grant” program aimed at offering “long-term perspectives and a prime viewpoint” in various disciplines.

She specified plans to allocate 500 million euros ($566 million) between 2025 and 2027 to “make Europe a beacon for researchers,” with funds directed to the European Research Council, which boasts a budget exceeding 16 billion euros ($18 billion) from 2021 to 2027.

Von der Leyen emphasized that the 27 EU nations aim to “institutionalize the freedom of scientific inquiry” with new legislation. “As global threats increase, Europe will not compromise on this principle,” she asserted.

Macron announced that the French government will shortly present new initiatives to bolster investments in science and research.

Recently, hundreds of university researchers in the U.S. faced funding cuts from the National Science Foundation due to an executive order from President Trump, impacting programs focused on diversity, equity, inclusion, and misinformation.

To date, over 380 grant projects have been eliminated, including efforts to combat internet censorship in China and Iran, as well as initiatives working with Indigenous communities to study environmental changes in Alaska’s Arctic.

Several of the affected grants aimed to diversify the demographics of individuals pursuing studies in science, technology, and engineering, prompting protests from scientists, researchers, and doctors in the streets.

While not explicitly naming the Trump administration, von der Leyen characterized the undermining of free and open research as a “huge miscalculation.”

“Science knows no borders, gender, ethnicity, or political affiliation,” she declared. “We believe that diversity is a vital human asset and the lifeblood of science. It is among the most valuable global resources and must be safeguarded.”

With von der Leyen seizing this opportunity, she is promoting European scientific avenues and leveraging the shift in U.S. policies. Trade relations have altered since Trump took office in January, including a tariff war that began last month.

The former German defense minister and trained medical doctor has committed to addressing obstacles faced by scientists and researchers, particularly regarding excessive bureaucracy and business access.

Macron stated that scientific research should not be dictated by a limited number of individuals.

Macron concluded, asserting that Europe “must become a sanctuary” for scientists and researchers, sending a clear message: “If you value freedom, come here to support our research, help us improve, and invest in our future.”

FTX: Investigating the disappearance of funds

SAm Bankman Fried, the former CEO of bankrupt cryptocurrency exchange FTX, oversaw a dramatic collapse that led to losses of billions of dollars for customers. In a court filing, he claims that all debts owed by FTX will be fully repaid. However, the US government views his statements as disconnected from reality.

Last week, FTX administrator John Ray III, appointed to manage the bankruptcy proceedings, accused Bankman Fried of orchestrating a massive fraud and living in a state of delusion. Ray dismissed the claims made by Bankman Fried’s lawyer that no one suffered harm as “categorically, callously, and patently false.”


Banker Mann Fried faces sentencing tomorrow after being convicted of fraud and money laundering conspiracy in the collapse of his cryptocurrency exchange. His potential 100-year prison sentence contrasts with a requested six-year term from his lawyer. The US government seeks a 40 to 50-year sentence for the 32-year-old former CEO who defrauded customers of $8 billion.

The Justice Department asserts that Bankman-Fried’s attempts to downplay his crimes and seek a lighter sentence reveal a dangerous potential for future fraud. The disputed bankruptcy proceedings for FTX may continue long after his release.

FTX: New technology, old embezzlement

This crypto entrepreneur created a façade of philanthropy by using client funds for personal luxuries, influencing political figures, and promoting the pseudo-altruistic philosophy of effective altruism. Recent testimonies have labeled FTX’s collapse as traditional embezzlement.

During the trial, evidence showed that $11.3 billion meant for customers was only $2.3 billion, with the rest diverted to investments, political contributions, and real estate, with little financial record-keeping. Wray likened the situation to a severe disaster caused by Bankman Fried’s deception.

What is the status of the influx of new venture funds?

More venture companies may be opening the champagne corks before the New Year. Several investment companies announced new funds today. Artis VenturesBoxGroup, Playground Global, and Singular have all suspended funding; Partek announced the launch of a 360 million euro venture fund.

The announcements come as something of a shock, especially coming so quickly against a backdrop of layoffs and continued economic uncertainty. But they point out some fundamental truths about the current market.

Institutional investors remain interested in venture capital as an asset class. With a more rational valuation, they think his 2024 is a good time to put money into startups. They also want to maintain relationships with venture companies that have made some promises in recent years, especially after a bit of a breather in 2023.

As Eric Hippeau, managing partner at Lerer Hippeau, told TechCrunch last year when the company raised $230 million for 2022, this is what will happen in 2021.[A]All of our limited partners were completely overwhelmed by people raising money twice a year or much more than they normally would. ”

The question is to what extent LPs are starting to loosen their purse strings, and despite today’s flurry of funding news, the answer is far from clear.

Steph Chiu, a partner at venture firm Portage, insists that “the funding environment remains tough.” She believes that what we are seeing is a result of continued interest in funds with strong track records and distributions on paid-in capital.

Karim Gharani, general partner at Luge Capital, agrees. Limited partners “will continue to support fund managers who believe they can not only consistently select these companies, but also participate in those transactions when they are competitive,” Galani said in an email.

Falling valuations may also attract the attention of institutional investors. Their portfolio managers may have been overpaying for trades in recent years due to frothy markets, and could be getting better deals with talented teams, at least for now. .

“If you have dry powder as a fund, now is the time to deploy it, because the best vintages in venture history have come from the post-valuation reset period,” Choo said in an email. “Some forward-thinking LPs are also looking at similar historical trends, along with broader macros (strong public market performance, calls for soft landings, etc.), which will likely lead to renewed interest next year. there is a possibility.”

Meanwhile, LPs may not be reacting too much to what’s just around the corner in 2024, but may be looking out over a longer time horizon, especially given that venture funds typically invest over 10-year time horizons. There is.

As Gallani points out, the announcement of so many new funds does not necessarily indicate that 2024 will be a “year of prosperity.” The venture industry, which is always a cyclical business, is likely to recover, and this recovery is likely to occur sooner or later.
