Revolutionary Quantum Computing Breakthrough: Secure Methods for Backing Up Quantum Information

Researchers from the University of Waterloo and Kyushu University have achieved a groundbreaking advancement in quantum computing by developing a novel method to create redundant, encrypted copies of qubits. This represents a pivotal step towards practical quantum cloud services and robust quantum infrastructure.

In quantum mechanics, the no-cloning theorem asserts that creating an identical copy of an unknown quantum state is impossible.

Dr. Achim Kempf from the University of Waterloo and Dr. Koji Yamaguchi from Kyushu University emphasize that this fundamental rule remains intact.

However, they have demonstrated a method to generate multiple encrypted versions of a single qubit.

“This significant breakthrough facilitates quantum cloud storage solutions, such as quantum Dropbox, quantum Google Drive, and quantum STACKIT, enabling the secure storage of identical quantum information across multiple servers as redundant encrypted backups,” said Dr. Kemp.

“This development is a crucial step towards establishing a comprehensive quantum computing infrastructure.”

“Quantum computing offers immense potential, particularly for addressing complex problems, but it also introduces unique challenges.”

“One major difficulty in quantum computing is the no-duplication theorem, which dictates that quantum information cannot be directly copied.”

“This limitation arises from the delicate nature of quantum information storage.”

According to the researchers, quantum information functions analogously to splitting passwords.

“If you possess half of a password while your partner holds the other half, neither can be utilized independently. However, when both sections are combined, a valuable password emerges,” Dr. Kemp remarked.

“In a similar manner, qubits are unique in that they can share information in exponentially growing ways as they interconnect.”

“A single qubit’s information is minimal; however, linking multiple qubits allows them to collectively store substantial amounts of information that only materializes when interconnected.”

“This exceptional capability of sharing information across numerous qubits is known as quantum entanglement.”

“With 100 qubits, information can be simultaneously shared in 2^100 different ways, allowing for a level of shared entangled information far exceeding that of current classical computers.”

“Despite the vast potential of quantum computing, the no-cloning theorem restricts its applications.”

“Unlike classical computing, where duplicating information for sharing and backup is a common practice, quantum computing lacks a simple ‘copy and paste’ mechanism.”

“We have uncovered a workaround for the non-replicability theorem of quantum information,” explained Dr. Yamaguchi.

“Our findings reveal that by encrypting quantum information during duplication, we can create as many copies as desired.”

“This method circumvents the no-clonability theorem because when an encrypted copy is selected and decrypted, the decryption key is automatically rendered unusable; it functions as a one-time key.”

“Nevertheless, even one-time keys facilitate crucial applications such as redundant and encrypted quantum cloud services.”

The team’s research will be published in the journal Physical Review Letters.

Virginia Democrats Advocate for Data Centers to Secure State House Seat

JOrne McAuliffe, a 33-year-old entrepreneur and former public servant, stands as an unexpected Democratic contender in this month’s Virginia House of Representatives election, especially given a campaign approach that occasionally resembled that of his Republican opponents.

Recently, Mr. McAuliffe joined 13 Democrats who secured Congressional seats in Virginia during a significant electoral win for his party, granting them robust control over state governance. With victories in states like New Jersey and California, this outcome provides a renewed advantage for Democrats nationwide, following a disheartening setback against Donald Trump and the Republican Party the previous year.

The northern Virginia district he aimed to represent, characterized by residential areas, agricultural land, and charming small towns, hadn’t seen a Democratic representative in decades. Thus, McAuliffe campaigned door-to-door on his electric scooter, reaching out to constituents with a pledge to “protect their way of life.” He dismissed the label “woke” and attributed the “chaos” to Washington, D.C., located over an hour away.


One of his primary talking points was a widespread concern resonating with many Democrats today, but with a distinct angle: the adverse impacts of data centers on electricity costs.

“I spent a majority of the year visiting households I never imagined were Democratic,” McAuliffe recounted. “Independents, Republicans, and an occasional Democrat, yet many began shutting their doors on me.”

“However, once they voiced a desire to discuss data centers, it opened a dialogue. That allowed me to draw a contrast, which is rare.”

Loudoun County’s data centers occupy about half of Virginia’s 30th House District, known for its high per capita income, and handle more traffic than any other region globally. While essential for many Internet functions, McAuliffe argued—and many voters concurred—that their presence can be burdensome.

Sizeable as warehouses, these data centers loom over nearby neighborhoods, buzzing with the sounds of servers and machinery. Developers seek to establish facilities in Fauquier County, the district’s other Republican-leaning area, but McAuliffe mentioned that residents are apprehensive about construction on rural farmland, renowned for its scenic vistas. He noted receiving complaints regarding the impact of data centers on electricity bills across the board.

According to a 2024 report from the Virginia General Assembly’s Joint Legislative Audit and Review Committee, the state’s energy demands are projected to double over the next decade, chiefly due to data centers and the substantial infrastructure required to cater to this demand.

The report also indicated that while Virginia’s electricity pricing structures are “appropriately” aligned with facility usage, “energy costs for all consumers are likely to rise” to cover new infrastructure expenses and necessary electricity imports. Earlier this month, Virginia’s public utility regulators approved a rise in electricity rates, though not to the extent Dominion Energy, the state’s primary provider, initially requested.

“The costs tied to infrastructure—the extensive transmission lines and substations—are being passed down to consumers,” McAuliffe explained from a co-working space in Middleburg, Virginia, where his campaign operates.

“These essentially represent taxes that we’ve wrongfully placed on ordinary Virginians to benefit corporations like Amazon and Google. While there may be some advantages for these communities, these companies are capable of affording them, and we must strive to better negotiate those benefits.”

McAuliffe’s opponent was Republican Geary Higgins, who had been elected in 2023. The battle between the two parties proved costly, with Democrats investing nearly $3 million and their adversaries spending just over $850,000, according to records from the Virginia Public Access Project.

This campaign encompassed more than just data centers; McAuliffe also spotlighted reproductive rights and teacher salary increases. Democrats have committed to codifying access to abortion if they gain full power in Virginia’s state government, and the governance in his district deteriorated under Democratic Party criticisms that Higgins failed to return contributions from controversial politicians.

Yet, McAuliffe chose to concentrate on data centers, believing their impacts presented “the most pressing issue we can address.” This focus surprised some of his consultants, and although he acknowledged it was a “somewhat niche topic,” data centers frequently emerged as a primary concern during his door-to-door visits.

To counter Higgins, his campaign even launched a website called data center geary, attempting to associate the Republican (a former Loudoun County Supervisor) with the spread of these facilities. Higgins and his family and allies condemned the efforts as misleading.

Mr. McAuliffe ultimately won with 50.9% of the votes, while Mr. Higgins gathered 49%. In response to a request for an interview, Higgins stated that McAuliffe’s “entire campaign was based on falsehoods regarding me and my history.”

“Thanks to an influx of external funding and high Democratic turnout, he was able to fabricate a misleading caricature of me and narrowly triumph,” Higgins remarked.

As Mr. Trump faced the polls nationwide last year, voters in conservative rural and suburban areas turned away from Democrats, resulting in the party’s loss of the presidency and Congressional control. McAuliffe’s victory leaves some party leaders pondering the lessons Democrats can glean from his campaign.

“In typically red regions, he identified common issues that resonated with both Republicans and Democrats while making a convincing case for solutions,” noted Democratic Rep. Suhas Subrahmanyam, who represents McAuliffe’s district.

Democratic National Committee Chairman Ken Martin, who campaigned alongside McAuliffe, characterized him as “an extraordinary candidate who triumphed by focusing squarely on the relevant issues of his district.”

“Democrats are capable of winning in any setting, especially in suburbs and rural environments, when they have candidates who commit themselves to addressing the genuine needs of their community. Presently, what Americans require is the capability to manage their expenses,” stated Martin.

Chaz Natticomb, founder and executive director of Virginia’s nonpartisan election monitoring organization State Navigate, remarked that while McAuliffe may not have surpassed Democrat Abigail Spanberger’s standout gubernatorial victory, his success in garnering votes illustrates his appeal to some Republicans over Higgins.

“He outperformed everyone else, primarily because he gained the support of Republican-leaning voters,” Natticombe concluded.

Matthew McConaughey and Michael Caine Secure Voice Agreement with AI Firm

Academy Award-winning actors Matthew McConaughey and Michael Caine have entered into an agreement with AI audio firm Eleven Labs.

The New York-based company is now authorized to produce AI-generated voice replicas as part of its initiative to tackle “significant ethical challenges” in the intersection of artificial intelligence and Hollywood.


McConaughey, who has also invested in the company and collaborated with them since 2022, will allow Eleven Labs to produce a Spanish audio version of his newsletter “Lyrics of Livin'” using his voice.

In a statement, the Dallas Buyers Club star expressed his admiration for Eleven Labs and hoped this collaboration would enable him to “reach and connect with an even broader audience.”

Eleven Labs is launching the Iconic Voices Marketplace, allowing brands to collaborate and utilize officially licensed celebrity voices for AI-generated applications. Caine’s new agreement includes his iconic voice in this lineup.

“For years, I have lent my voice to stories that inspire people—tales of bravery, ingenuity, and the human experience,” Caine stated. “Now, I am helping others to discover their voice. With Eleven Labs, I can save and share everyone’s voice, not just mine.”

He further mentioned that the company “leverages innovation to celebrate humanity, not to replace it,” asserting that it “does not replace voices, it amplifies them.”


Caine has also revealed plans to return from retirement to co-star with Vin Diesel in The Last Witch Hunter 2.

Other voices featured in the marketplace include legendary Hollywood figures like John Wayne, Rock Hudson, and Judy Garland, alongside contemporary stars such as Liza Minnelli and Art Garfunkel. The list also encompasses notable figures like Amelia Earhart, Babe Ruth, J. Robert Oppenheimer, Maya Angelou, and Alan Turing.

Recently, Eleven Labs was valued at approximately $6.6 billion.

This news follows a series of celebrity and AI partnership agreements, including various celebrities who have consented to allow Meta to utilize their voices. Last year, the company released a list that featured Judi Dench, John Cena, and Kristen Bell.

Other stars, including Ashton Kutcher and Leonardo DiCaprio, have also made investments in AI enterprises.

Academic Papers Allegedly Use AI Text to Secure Positive Peer Reviews

An academic is reportedly concealing prompts in preprint papers for artificial intelligence tools, encouraging these tools to generate favorable reviews.

On July 1st, Nikkei reported that we examined research papers from 14 academic institutions across eight countries, including two in Japan, South Korea, China, Singapore, and the United States.

The papers found on the research platform Arxiv have not yet gone through formal peer review, and most pertain to the field of computer science.

In one paper reviewed by the Guardian, there was hidden white text located just beneath the abstract statement.


Nikkei also reported on other papers that included the phrase “Don’t emphasize negativity,” with some offering precise instructions for the positive reviews expected.

The journal Nature has also identified 18 preprint studies containing such concealed messages.

The trend seems to originate from a social media post by Jonathan Lorraine, a Canada-based Nvidia Research Scientist, suggesting the avoidance of “stricken meeting reviews from reviewers with LLM” that incorporate AI prompts.

If a paper is peer-reviewed by humans, the prompts might not cause issues, but as one professor involved with the manuscript mentioned, it counters the phenomenon of “lazy reviewers” who rely on others to conduct their peer review work.

Nature conducted a survey with 5,000 researchers in March and found that nearly 20% had attempted to use a large language model (LLM) to enhance the speed and ease of their research.

Biodiversity academic Timothee Poisau at the University of Montreal revealed on his blog in February that doubts arose regarding a peer review because it contained output from ChatGPT, referring to it as “blatantly written by LLM” in his review, which included “here is a revised version of the improved review.”

“Writing a review using LLM indicates a desire for an assessment without committing to the effort of reviewing,” Poisot states.

“If you begin automating reviews, as a reviewer, you signal that providing reviews is merely a task to complete or an item to add to your resume.”

The rise of a widely accessible commercial language model poses challenges for various sectors, including publishing, academia, and law.

Last year, Frontier of Cell and Developmental Biology gained media attention for including AI-generated images depicting mice standing upright with exaggerated characteristics.

Mrbeast, YouTube sensation, set to secure investment round valuing his company at $5 billion

MrBeast, the world’s largest YouTube star, is planning to raise hundreds of millions of dollars in a move that could value the company at approximately $5 billion (£3.9 billion).

The YouTuber, whose real name is Jimmy Donaldson, has reportedly been in discussions with various wealthy individuals and financial companies regarding participation in the investment round.

The funds are intended to establish a holding company for his expanding empire, which includes a video production company, a chocolate brand called Feast, and a snack business named Lunch. According to Bloomberg, the money could also be used to expand his media and merchandise packaging business.

The talks regarding potential funding are still in the early stages, and it is unclear who will invest and at what valuation. This would not be his first fundraising round, as he has previously secured investments from companies such as New York-based Alpha Wave Global.

If successful, the new funds would help Donaldson further expand his business. With over 368 million subscribers on his channel, he is already the world’s largest YouTuber.

The 26-year-old from Wichita, Kansas, is known for his videos featuring stunts, challenges, and cash giveaways. One of his most popular viral videos involved recreating the set from the Netflix series Squid Game, costing $3.5 million. The challenge had 456 participants competing for a prize of $456,000.

He has also launched the reality competition show “Beast Games” on Amazon, which had limited viewership last month.

Like many YouTubers, Donaldson started on the platform in 2012 and has since ventured into food brands like Fastables and MrBeast Burgers.

Despite earning tens of millions of dollars annually, he is also known for his charitable efforts. Much of his earnings are reinvested into his videos and philanthropy.

However, his work has not been without criticism. He has faced backlash for a history of homophobic comments as a teenager and being a demanding employer. Some have labeled his content as “poverty porn,” claiming that people only benefit from cash, prizes, and gifts by appearing in his videos. Despite the criticism, his efforts to fund cataract surgery for 1,000 people to restore their vision were praised by charities.
