QuEra’s Libra fault-tolerant quantum computer due in 2028

Published

on


QuEra Computing has announced Libra, its first fault-tolerant quantum computer, and plans to make the system available on Amazon Braket in 2028.

It has also expanded its multi-year strategic collaboration with Amazon Web Services, with Libra becoming the first system covered by the broader agreement.

The Boston-based quantum computing company describes Libra as a megaquop-class machine, a term it uses for a system intended to carry out about one million reliable logical quantum operations. The machine is projected to offer more than 256 error-corrected logical qubits and a logical error rate of 10−6.

Fault-tolerant quantum computing is widely viewed as a key step beyond today’s error-prone systems because it is intended to support longer, more dependable calculations. QuEra says this could open a path to early commercial and research workflows in fields such as molecular simulation, materials discovery and optimisation, where classical computing methods can struggle as problems grow larger.

AWS link

Under the arrangement, AWS customers will be able to access Libra through Amazon Braket, the cloud group’s managed quantum computing service. AWS says Braket gives users a single environment to build and run quantum applications alongside existing classical infrastructure, including high-performance computing, artificial intelligence and machine learning services.

The tie-up extends a relationship that began in 2022, when QuEra’s Aquila system became available on Amazon Braket. Aquila is a 256-physical-qubit neutral-atom quantum computer, while QuEra’s Gemini system, which the company says has logical-qubit functions, is co-located with the ABCI-Q supercomputer in Japan.

Andy Ory, chief executive officer of QuEra Computing, said the company sees the announcement as part of a broader shift in the industry.

“Fault-tolerant quantum computing is moving from a scientific milestone to an engineering and deployment roadmap,” Ory said.

“We have executed this roadmap in the open, with peer-reviewed milestones and validated system advances. Libra brings fault-tolerant computing to the cloud at scale in 2028. It is an important step forward, and subsequent generations will scale even further, as we will reveal in our roadmap webinar later this month. We are inviting leaders to engage now so they can build the talent, use cases and workflows needed to be ready when these systems come online,” he said.

Research base

QuEra says every building block of the Libra architecture has already been validated in peer-reviewed research. It points to eight papers in Nature and Physical Review Letters by its teams and by researchers in the laboratories of its scientific founders at Harvard and MIT.

According to the company, the papers cover logical qubits, below-threshold error correction, transversal logical operations, fast decoding for real-time error correction, sustained operation of thousands of qubits with continuous atom reloading, and error-correcting codes intended to reduce the number of physical qubits needed for each logical qubit.

Neutral-atom quantum computing has drawn increasing attention as one of several technical approaches in the race to build practical quantum systems. QuEra’s strategy has focused on demonstrating error correction and then scaling towards fault tolerance, rather than only increasing raw qubit counts.

Amazon Web Services says the collaboration reflects its view that fault-tolerant quantum systems will become part of customers’ computing environments.

“We believe fault-tolerant quantum computing will become a foundational part of how customers solve their hardest computational problems on AWS. QuEra’s technology has demonstrated a clear path to that future. By bringing these capabilities to customers through Amazon Braket, they can combine QuEra’s fault-tolerant quantum processors with the scalable AWS HPC and AI services they already rely on,” said Eric Kessler, general manager of Amazon Braket at AWS.

Commercial pressure

QuEra is also using the announcement to urge potential users to prepare for fault-tolerant systems before they become commercially available. It plans to keep building successive in-house generations of fault-tolerant systems ahead of Libra’s release, both to refine the design and to give selected partners earlier access to working environments.

Yuval Boger, chief commercial officer of QuEra, said organisations that delay planning could lose time once the systems arrive.

“Waiting until 2028 to build a quantum strategy is a competitive risk,” Boger said.

“The algorithms that will harness fault-tolerant systems at this scale might not yet exist. Given that Libra will be available on the cloud in 2028 with a one-in-a-million error rate, the organizations that start co-developing now will be operational on day one, not catching up,” he said.

Industry analysts say the announcement marks an important moment for a field often criticised for setting ambitious targets without enough technical disclosure. QuEra’s emphasis on peer-reviewed milestones appears intended to distinguish its timetable from less transparent claims in the sector.

“QuEra’s plan to deliver fault-tolerant systems in 2028 represents a significant inflection point for the quantum computing industry. QuEra’s approach entails publishing every milestone, validating through peer review and now offering concrete QC end-user engagement paths. This disciplined and visible strategy is what aspiring QC end users in HPC centres and related government programs want to see before committing substantial resources to an emerging technology,” said Bob Sorensen, chief analyst for quantum computing at Hyperion Research.

Over 100 MPs call for Thames Water to go into special administration

Published

on


One hundred and 12 members of parliament have signed an open letter to the environment secretary and Ofwat, the water services regulation authority, calling for Thames Water to be placed into special administration without delay.

Since June 2025, Thames Water creditors, a group of US hedge funds, has been negotiating with Ofwat to formally take over the utility.

The proposed deal includes waiving fines for the water company, suspend pollution and performance targets, and raise bills for households beyond the level currently set by Ofwat.

Calum Miller, MP for Bicester and Woodstock, Olly Glover, MP for Didcot and Wantage, Freddie Van Mierlo, MP for Henley and Thame, Layla Moran, MP for Oxford West and Abingdon, and Charlie Maynard, MP for Witney all signed the list.

In total 53 Liberal Democrats signed the list, 46 Labour MPs, six independents, five Green party MPs, one from Plaid Cymru and one from the Conservative party.

The letter highlights the dangerous possibilities of the company setting its own rules would create a dangerous precedent for all of England’s privatised water companies.

Thames Water was responsible for a third of the worst pollution incidents in 2025.

The CEO of the company, Chris Weston, recently drew controversy for saying that some of the firm’s targets were beyond what they could achieve.

The comments came after he gave himself a 14 per cent pay rise to £1.163 million in the year to March, while other directors received bonuses totalling £4.1 million

Professor says tokenised deposits won’t transform banking

Published

on


A Loughborough University study has challenged claims that tokenised bank deposits will transform banking, arguing that many of the supposed benefits can already be delivered through existing systems.

The paper examines tokenised deposits, which represent money held in a bank account as a digital token, and questions whether they amount to a significant innovation for mainstream banking. Supporters say the model could improve the speed and automation of payments. The study argues that these outcomes do not depend on tokenisation.

Professor Alistair Milne of Loughborough Business School wrote the policy note for SUERF, a group that brings together central bankers, regulators, academics and finance professionals. He argues that banks already use computer systems and databases that can be programmed to handle many of the same tasks now being presented as new.

Debate over digital money has gathered pace as banks, policymakers and financial technology groups explore alternatives to traditional account-based systems. Tokenised deposits have emerged as one of several concepts under discussion, alongside stablecoins and central bank digital currencies. Advocates say they could help create faster payments, available at all hours and easier to link to automated instructions.

Milne’s paper takes a narrower view of what is actually new. It argues that blockchain, the record-keeping technology often associated with cryptocurrencies such as Bitcoin, is not necessary for most of the practical gains linked to tokenised deposits. In his assessment, conventional bank infrastructure can already support much of the same functionality without converting deposits into tokens.

“Much of the current discussion suggests tokenised deposits will transform banking. My research indicates that the technology itself is not the key issue. Most of the promised advantages can already be achieved using conventional banking systems. In many cases, tokenised deposits are better understood as a new way of packaging existing capabilities rather than a fundamentally new form of money,” said Professor Alistair Milne, Loughborough Business School, Loughborough University.

The study does not dismiss tokenised deposits entirely. Instead, it identifies a limited set of circumstances in which they may offer a clearer advantage, particularly within the operations of large international banks serving corporate clients across several markets.

Cross-border use

One of the stronger use cases, the paper argues, arises when a global company moves money between countries and currencies within the same banking group. In that situation, payments can be automated more easily because the transfer remains within one bank’s internal systems rather than moving through several institutions.

That distinction matters because payments between different banks still require interbank settlement. This brings a series of established constraints, including regulation, security checks and the management of financial risk between institutions.

The paper argues that tokenising a deposit does not remove those underlying frictions. Even if the customer-facing representation of money changes, banks must still complete the same core settlement and compliance steps when funds move across institutional boundaries.

Wider debate

The findings add to a broader policy discussion over whether new forms of digital money represent genuine structural change or simply a redesign of existing financial processes. Banks and regulators have been assessing how far distributed ledger systems can improve payments, settlement and record-keeping, especially in wholesale and cross-border markets.

Milne’s intervention is likely to resonate with those who question whether the financial sector is overstating the novelty of token-based systems. The paper suggests the real barriers to better payments are not always technological, but often lie in the legal, regulatory and risk frameworks that govern transactions between separate institutions.

The paper also highlights a divide in the digital money debate. Some proposed systems promise gains by changing the form of money itself, while others seek improvements through better integration of existing infrastructure. Milne’s argument places tokenised deposits closer to the second category.

For banks, that could shape investment decisions. If the same results can be achieved through upgrades to current databases and payment systems, the commercial case for shifting to tokenised deposits may be weaker than some advocates suggest, especially in domestic banking where established systems are already deeply embedded.

At the same time, the paper leaves room for more targeted adoption where specific operational benefits can be shown. Large multinational banks handling internal cross-border flows may still find token-based structures useful in defined cases, even if the model falls short of a broader banking revolution.

The study’s central conclusion is that the hardest parts of modern payments do not disappear simply because deposits are represented differently in software. As Milne argues, the most important constraints often emerge when money must move between institutions rather than within them.

Those frictions remain central to banking, regardless of whether a deposit is recorded in a conventional account ledger or represented as a token. The paper argues that turning deposits into digital tokens does little to remove these underlying challenges.

UK restaurant chain bids final farewell in emotional goodbye

Published

on


The closures, including branches in Oxfordshire, are part of the parent company Whitbread’s major restructuring plan, and will see all 106 sites shut permanently.

It was announced in April that the company would shut its remaining Beefeater and Brewers Fayre sites as part of a strategy overhaul, placing around 3,800 jobs at risk.

There are Beefeaters in Cowley and Kidlington.

Now the chain has reached out to its loyal customers.

In an email being distributed to previous diners and members of its loyalty schemes, Beefeater shared a message of gratitude, with two prominent words: ‘thank you’.

It said: “A message from your local Beefeater: We want to say a huge thank you for your custom at our Beefeater restaurants.”

It added: “As you may have seen, we have recently announced changes to our business, which is resulting in the closure of our Branded Restaurants.

“This means that on Thursday, September 10, 2026, your local Beefeater and all other UK Beefeaters will close.”

In the letter, the company also said it would close the loyalty scheme on August 31.

The restructure is part of Whitbread’s new five-year strategy, which aims to reduce costs by £250m.

The chain first launched in 1974.

Several customers said they were “sad” to see the chain shutting sites, although they also felt the brand had gone downhill in more recent years.

One person wrote: “Until I went to university the only restaurant I’d ever been to was a Beefeater. We’d go for various family birthdays. I absolutely loved it.

“A steak or a mixed grill, which I never got at home, followed by a Knickerbocker Glory. Fantastic times. I went back a couple of years ago.

“The place looked run down. I feel sad about this, but I guess the fact I hadn’t been to one for 30 years is part of the problem.”

The Ock Mill Beefeater restaurant, linked to the former Premier Inn in Marcham Road, Abingdon, closed in 2023, and the site was bought by the Unicorn School, which is currently renovating the building for classrooms.

Dominic Paul, Whitbread’s chief executive, said earlier: “We always challenge ourselves to improve and, in light of significant cost increases in the form of business rates and national insurance, as well as the implied market discount to our inherent value, we’ve looked hard at the options open to us to maximise value creation over the medium and long-term.

“This has been a rigorous process, and we’ve approached all options with an open mind.

“Our new five-year plan builds on our strengths and drives a significant acceleration of our strategy.”
