A quantum computer has enabled researchers to create the most complex time crystal to date, demonstrating its growing role as a powerful tool for scientific discovery. The experiment illustrates how a quantum computer can explore physical behaviours that are extremely difficult to simulate on conventional computers.
The study reinforces the importance of quantum computing for national research and innovation strategies. By allowing scientists to simulate complex quantum materials and map their possible states, a quantum computer could support future advances in materials science, sensing, and energy-related technologies.
At the same time, the findings highlight the need for realistic governance and balanced research policies. Current quantum computers remain prone to errors and must be used alongside classical methods, underlining the value of hybrid approaches in publicly funded research programmes.
The research also illustrates the importance of international collaboration and shared infrastructure in frontier science. Partnerships between research institutions and technology providers are expected to play a key role in accelerating progress and maintaining competitiveness in quantum science and advanced computing.

Amazon is implementing a major round of job cuts while investing more heavily in AI and cloud infrastructure. The latest announcement brings planned reductions to roughly 30,000 roles across corporate teams worldwide.
Senior vice president Beth Galetti said the layoffs aim to reduce management layers, speed up decision-making, and remove organisational bureaucracy. Media reports suggest the cuts represent close to 10 percent of Amazon’s global office workforce, while warehouse and logistics roles remain unaffected.
No specific divisions were named, with the company stating that each team will continue reviewing capacity and operational efficiency. Amazon previously reported spending $1.8 billion on severance linked to restructuring efforts, with full-year financial results due in early February.
The reductions mirror a broader trend across big tech, with Microsoft, Meta, ASML, HP, and Oracle also trimming white-collar management roles. Executives across the sector have framed the changes as cultural and structural rather than budget-driven.
At the same time, Amazon is boosting AI, cloud, and chip investments through AWS, including over $35 billion in data centre expansion in India amid rising competition.

WhatsApp rejected a class-action lawsuit accusing Meta of accessing encrypted messages, calling such claims false. The company reaffirmed that chats remain protected by device-based Signal protocol encryption.
Filed in a US federal court in California, the complaint alleges Meta misleads more than two billion users by promoting unbreakable encryption while internally storing and analysing message content. Plaintiffs from several countries claim employees can access chats through internal requests.
WhatsApp said no technical evidence accompanies the accusations and stressed that encryption occurs on users’ devices before messages are sent. According to the company, only recipients hold the keys required to decrypt content, which are never accessible to Meta.
The firm described the lawsuit as frivolous and said it will seek sanctions against the legal teams involved. Meta spokespersons reiterated that WhatsApp has relied on independently audited encryption standards for over a decade.
The case highlights ongoing debates about encryption and security, but so far, no evidence has shown that message content has been exposed.

EU member states are preparing to open formal discussions on the risks posed by AI-powered deepfakes and their use in cyberattacks, following an initiative by the current Council presidency.
The talks are intended to assess how synthetic media may undermine democratic processes and public trust across the bloc.
According to sources, capitals will also begin coordinated exchanges on the proposed Democracy Shield, a framework aimed at strengthening resilience against foreign interference and digitally enabled manipulation.
Deepfakes are increasingly viewed as a cross-cutting threat, combining disinformation, cyber operations and influence campaigns.
The timeline set out by the presidency foresees structured discussions among national experts before escalating the issue to the ministerial level. The approach reflects growing concern that existing cyber and media rules are insufficient to address rapidly advancing AI-generated content.
An initiative that signals a broader shift within the Council towards treating deepfakes not only as a content moderation challenge, but as a security risk with implications for elections, governance and institutional stability.

Scientists are divided over when quantum computers will become powerful enough to break today’s digital encryption, a moment widely referred to as ‘Q–Day’.
While predictions range from just two years to several decades, experts agree that governments and companies must begin preparing urgently for a future where conventional security systems may fail.
Quantum computing uses subatomic behaviour to process data far faster than classical machines, enabling rapid decryption of information once considered secure.
Financial systems, healthcare data, government communications, and military networks could all become vulnerable as advanced quantum machines emerge.
Major technology firms have already made breakthroughs, accelerating concerns that encryption safeguards could be overwhelmed sooner than expected.
Several cybersecurity specialists warn that sensitive data is already being harvested and stored for future decryption, a strategy known as ‘harvest now, decrypt later’.
Regulators in the UK and the US have set timelines for shifting to post-quantum cryptography, aiming for full migration by 2030-2035. However, engineering challenges and unresolved technical barriers continue to cast uncertainty over the pace of progress.
Despite scepticism over timelines, experts agree that early preparation remains the safest approach. Experts stress that education, infrastructure upgrades, and global cooperation are vital to prevent disruption as quantum technology advances.

TikTok says recovery of its US infrastructure is progressing, although technical issues continue to affect parts of the platform after a data centre power outage.
The disruption followed the launch of a new US-based entity backed by American investors, a move aimed at avoiding a nationwide ban.
Users across the country reported problems with searches, video playback, posting content, loading comments and unexpected behaviour in the For You algorithm. TikTok said the outage also affected other apps and warned that slower load times and timeouts may persist, rather than returning to normal performance.
In a statement posted by the TikTok USDS Joint Venture, the company said collaboration with its US data centre partner has restored much of the infrastructure, but posting new content may still trigger errors.
We've made significant progress in recovering our U.S. infrastructure with our U.S. data center partner. However, the U.S. user experience may still have some technical issues, including when posting new content. We're committed to bringing TikTok back to its full capacity as…
Creators may also see missing views, likes, or earnings due to server timeouts rather than actual data loss.
TikTok has not named the data centre partner involved, while severe winter storms across the US may have contributed to the outage. Despite growing scepticism around the timing of the disruption, the company insists that user data and engagement remain secure.
