Google warns quantum computers could hack encrypted systems by 2029

Banks, governments and technology providers need to be prepared for quantum computer hackers capable of breaking most existing encryption systems by 2029, Google has warned.The tech company said in a blogpost that quantum computers would pose a “significant threat to current cryptographic standards” before the end of the decade and urged other companies to follow its lead.The company, owned by Alphabet, said: “The encryption currently used to keep your information confidential and secure could easily be broken by a large-scale quantum computer in coming years.”As it stands, quantum computers – which can rapidly carry out complex tasks – are a nascent technology with great potential and significant obstacles to being widely usable.Google, Microsoft and universities across the UK and the US are in the midst of building systems that harness the physics of quantum mechanics to perform extremely sophisticated mathematical calculations.

Most of these systems are prohibitively difficult to build, requiring, for example, massive amounts of helium to cool quantum systems to near-absolute zero temperatures, or weeks of work aligning lasers.Those that are working at the moment are too small to perform the tasks that most excite the scientific community.Constructing a very powerful quantum computer – with hundreds of thousands or even millions of stable qubits, or quantum bits – will require overcoming physical and technological challenges to keep those qubits stable, given the inherently fragile nature of quantum systems.Google said: “We’ve adjusted our threat model to prioritise post-quantum cryptography migration for authentication services – an important component of online security and digital signature migrations.We recommend that other engineering teams follow suit.

”Leonie Mueck, formerly the chief product officer of Riverlane, a Cambridge-based quantum startup, said Google’s statement did not necessarily suggest there would definitely be a working quantum computer capable of breaking encryption by 2029,In fact, most timelines for a cryptographically relevant quantum computer – that is, one powerful enough to break encryption – range from the 2030s to the 2050s,But Mueck said the prospect was close enough that governments were already preparing for the eventuality that data stored to today’s encryption standards would be exposed when the technology sufficiently advances,“We’re basically seeing in the intelligence community already that for probably more than a decade they’ve been thinking about this threat,” Mueck said,Last year the UK’s cybersecurity agency, the National Cyber Security Centre, urged organisations to guard their systems against quantum hackers by 2035.

Google’s timeline suggests engineering teams across the technology industry should consider measures to protect sensitive data by migrating to more advanced encryption systems now,Certain kinds of attacks predicated on the future availability of quantum decryption – “store now, decrypt later” – may currently be being deployed across the field,Mueck said: “National security documents from 1920 are not relevant today,But stuff from 10 years ago is much more relevant, and should not get into the wrong hands in the future,You need to have classified documents that are classified today in a way that a quantum computer in 10 years won’t be able to decrypt them.

Two salon owners wanted to go zero-waste. Could they do it and keep their business afloat?

Scisters Salon & Apothecary in the San Diego area is committed to sustainable beauty and going low-wasteThe first thing you notice when you walk into Scisters Salon & Apothecary is what isn’t there. No wall of glossy plastic bottles promising “repair” or “shine”. No sharp chemical tang or aerosol haze. The only trash can is a tiny basket that mostly collects coffee cups and gum wrappers clients bring from home.Instead, the shelves of this southern California salon are lined with large refill containers of shampoo and conditioner, houseplants dot the space, hair clippings are swept away for compost, and the air carries a trace of bergamot and vanilla

Ministers vow to spend record £8.4bn on road maintenance in England

Ministers have pledged to spend record amounts on road maintenance as part of a £27bn five-year investment plan for England’s major roads and motorways.The government said it was aiming to “fix the foundations” with almost a third, £8.4bn, of the spending going on maintenance, including resurfacing a quarter of England’s strategic road network.However, campaigners said the plan – the government’s third road investment strategy, known as RIS3 – was still building needless new roads, with funding approved for 16 schemes.That includes £1

Ticketmaster quietly raised other fees after US crackdown on hidden charges

Following a wave of regulations banning the surprise fees that appear at the end of a transaction, Ticketmaster stopped charging the extra few dollars it added to each order at checkout. Typically shared with the venue, the order processing fee was a boon to a global platform that sells hundreds of millions of tickets a year.But documents obtained by the Guardian show that while Ticketmaster eliminated this fee to comply with the rules, the company simply raised the cost of different fees in a number of its venues to ensure it didn’t lose money.“To account for the loss of order processing revenue, we must adjust fees to offset the revenue loss,” Ticketmaster wrote in an email to the Findlay Toyota Center in Arizona last year. The venue eliminated a $6 order processing fee, but raised the service fee on each ticket by $2 instead

Co-op boss quits after year marked by cyber-attack and claims of ‘toxic’ culture

The Co-op Group has announced that its chief executive will step down this weekend after a difficult year that included a cyber-attack and recent claims of a “toxic” culture at the business.Shirine Khoury-Haq will depart on 29 March and Kate Allum, a board member and former boss of the dairy group First Milk, will step in as interim boss while a permanent replacement is sought.News of the exit came as the company, which owns more than 800 funeral parlours and an insurance and legal advisory business, as well as operating more than 2,000 convenience stores, dived to an underlying loss of £125m.The drop from a £45m profit the year before came after it took a £107m profits hit from the damaging IT hack, which forced it to shut down some systems.On Thursday, Khoury-Haq denied that her resignation was linked to the allegations of a toxic culture

Australian growth forecasts slashed as global economy faces inflation spike

The world economy is on the brink of a major inflationary spike as soaring fuel prices threaten growth in European and Asian nations, the OECD has warned, and local economists are slashing Australia’s growth prospects for this year and the next amid the ongoing US-Israel attack on Iran.The Organisation for Economic Cooperation and Development’s latest interim outlook said the US-Israel war on Iran will “test the resilience of the global economy” and warned of the “significant downside risk” to their forecasts should the oil supply disruptions prove more persistent and push energy prices even higher.The Paris-based organisation predicted inflation across G20 countries would reach 4% through 2026, or 1.2 percentage points higher than anticipated in December and before the US-Israeli bombing of Iran led to the closure of the strait of Hormuz.The OECD downgraded growth across the Euro area countries, the UK and South Korea by 0

Middle East conflict will damage UK’s economy ‘more than any other’

The conflict in the Middle East will damage the UK’s economy more than any other industrialised nation, according to analysis by the Organisation for Economic Cooperation and Development (OECD), which warned over rising inflation.In the first major assessment by a leading international thinktank of the economic impact from the attack on Iran, the OECD said the UK economy would grow by just 0.7% this year, compared with its last forecast, made in December, of 1.2% for 2026.Illustrating the UK’s dependence on international trade and imports of fuel, the OECD said it had downgraded the UK’s growth in 2026 because it was likely to suffer higher inflation than previously expected
