India deepens ties with Finland and Denmark

India is intensifying its strategic ties with Finland and Denmark as part of a broader effort to deepen cooperation with key Nordic countries.

In recent high-level conversations, Prime Minister Narendra Modi spoke with Finland’s President Alexander Stubb and Denmark’s Prime Minister Mette Frederiksen.

These discussions focused on strengthening bilateral relations in advanced technologies such as quantum computing, 5G and 6G, AI, and cybersecurity, instead of limiting collaboration to traditional sectors. Sustainability, mobility, and digital transformation also featured prominently.

Modi and Stubb underlined the importance of India-Finland cooperation within the wider context of EU relations. Both leaders expressed hope for a timely conclusion of an India-EU free trade agreement, a sentiment echoed by European Commission President Ursula von der Leyen.

The collaboration aims to bolster efforts in AI for disaster response and climate resilience, secure telecommunications, and semiconductor development, especially given ongoing geopolitical shifts and the impact of the Russia-Ukraine conflict.

In parallel, Modi reaffirmed India’s commitment to the India-Denmark Green Strategic Partnership during talks with Frederiksen.

The alliance prioritises environmentally responsible maritime practices instead of relying on conventional methods, and promotes innovation in green technologies and anti-piracy cooperation.

With the third India-Nordic Summit scheduled for later this year in Norway, the focus will be on expanding trade, climate action, and peace efforts with all five Nordic nations.

Meanwhile, India has overtaken Finland as the ‘World’s Happiest Country’ according to the latest Ipsos survey, with 88% of Indian respondents reporting happiness.

A milestone like this reflects a broader sense of national optimism and self-assurance as India continues to strengthen its global partnerships and expand its strategic influence across key sectors.

Certified randomness achieved with quantum tech

Quantum researchers from JPMorgan Chase, Quantinuum and others have achieved a major milestone in cybersecurity by generating certified random numbers using a quantum computer.

The team’s work, recently published in Nature, showcases how quantum systems can create randomness that is mathematically proven to be unpredictable—an essential leap forward in securing systems like online banking and digital voting.

Traditional computers rely on pseudo-random algorithms to mimic randomness, which are ultimately deterministic and vulnerable if the algorithm or seed is uncovered.

By contrast, the team used Quantinuum’s 56-qubit trapped-ion quantum processor to produce over 70,000 certified random bits. The process is so complex that replicating it with current supercomputers would be practically impossible.

The results were independently verified, confirming that no algorithm was involved in generating the sequence.

The breakthrough goes beyond theoretical exercises often associated with quantum computing and demonstrates practical, real-world impact in cryptography, where random numbers must be truly unguessable to keep digital systems secure.

Quantum game shows power of entangled atoms

A team of physicists in collaboration with quantum computing company Quantinuum, has successfully tested a unique quantum game using lasers and atoms which demonstrates how quantum computers can outperform classical machines through a phenomenon known as quantum pseudotelepathy.

Using the Quantinuum System Model H1, researchers manipulated 20 ytterbium atoms arranged in a two-dimensional grid to create a “topological phase”, a highly stable, interconnected pattern of qubits.

These qubits, resistant to interference, enabled players to simulate a cooperative logic game where quantum entanglement allowed them to consistently solve tasks that classical players could not.

Achieving a success rate of around 95%, the study showcases the growing potential of current quantum hardware.

Although not a direct solution to global problems, it marks an important step in proving that quantum devices can already perform certain tasks that classical systems struggle with.

Quantum spin breakthrough at room temperature

South Korean researchers have discovered a way to generate much stronger spin currents at room temperature, potentially transforming the future of electronics.

By using a mechanism called longitudinal spin pumping and a special iron-rhodium material, the team showed that quantum magnetisation dynamics, once thought to only occur at extremely low temperatures, can take place in everyday conditions.

These currents were found to be 10 times stronger than those created through traditional methods, offering a major boost for low-power, high-performance devices.

Instead of relying on the movement of electric charge, spintronics makes use of the electron’s spin, which reduces energy loss and heat generation. This advancement could be particularly beneficial for Magnetoresistive Random Access Memory (MRAM), a type of memory that depends on spin currents to function.

Researchers believe their findings may significantly cut power consumption in MRAM, which is already being explored by companies like Samsung for next-generation AI computing systems.

The study, carried out by teams at KAIST and Sogang University, used a combination of ultrafast measurement experiments and theoretical analysis to validate the discovery. Experts say the results could lead to a new era of energy-efficient memory and processor technologies.

Instead of stopping here, the researchers now plan to develop novel spintronic device architectures and explore other quantum-based mechanisms to push the limits of what modern electronics can achieve.

Europe struggles to explain quantum to its citizens

Most Europeans remain unclear about quantum technology, despite increasing attention from EU leaders. A new survey, released on World Quantum Day, reveals that while 78 per cent of adults in France and Germany are aware of quantum, only a third truly understand what it is.

Nearly half admitted they had heard of the term but didn’t know what it means.

Quantum science studies the smallest building blocks of the universe, particles like electrons and atoms, that behave in ways classical physics can’t explain. Though invisible even to standard microscopes, they already power technologies such as GPS, MRI scanners and semiconductors.

Quantum tools could lead to breakthroughs in healthcare, cybersecurity, and climate change, by enabling ultra-precise imaging, improved encryption, and advanced environmental monitoring.

The survey showed that 47 per cent of respondents expect quantum to positively impact their country within five years, with many hopeful about its role in areas like energy, medicine and fraud prevention.

For example, quantum computers might help simulate complex molecules for drug development, while quantum encryption could secure communications better than current systems.

The EU has committed to developing a European quantum chip and is exploring a potential Quantum Act, backed by €65 million in funding under the EU Chips Act. The UK has pledged £121 million for quantum initiatives.

However, Europe still trails behind China and the US, mainly due to limited private investment and slower deployment. Former ECB president Mario Draghi warned that Europe must build a globally competitive quantum ecosystem instead of falling behind further.

Quantum breakthrough could be just years away

Most quantum professionals believe that quantum utility — the point at which quantum computers outperform classical machines in solving real-world problems — could be reached within the next decade.

According to a new survey by Economist Impact, 83% of global experts expect quantum utility to arrive in ten years or less, with one-third predicting it will happen in as little as one to five years.

Optimism aligns with some industry roadmaps, such as Finnish startup IQM, which is targeting quantum utility as early as next year.

However, there’s still little consensus on the timeline. While Google’s CEO Sundar Pichai recently suggested practically useful quantum computers could be five to ten years away, Nvidia’s Jensen Huang believes it may take at least 15 years — a remark that briefly shook confidence in quantum stocks.

Industry confusion over terms like ‘quantum utility,’ ‘advantage,’ and ‘supremacy’ only adds to the uncertainty, highlighting the need for clearer communication and better public understanding.

Despite the buzz, major challenges remain. Over 80% of professionals cite technical barriers, especially error correction, as a major hurdle.

A further 75% point to a lack of skilled talent in the field. While misconceptions about quantum computing are seen as slowing progress, the real bottlenecks lie in engineering and workforce development.

If these can be overcome, quantum computing could revolutionise sectors from pharmaceuticals and materials science to finance and cybersecurity — with profound implications, both promising and perilous.

IBM pushes towards quantum advantage in two years with breakthrough code

IBM’s Quantum CTO, Oliver Dial, predicts that quantum advantage, where quantum computers outperform classical ones on specific tasks, could be achieved within two years.

The milestone is seen as possible due to advances in error mitigation techniques, which enable quantum computers to provide reliable results despite their inherent noise. While full fault-tolerant quantum systems are still years away, IBM’s focus on error mitigation could bring real-world results soon.

A key part of IBM’s progress is the introduction of the ‘Gross code,’ a quantum error correction method that drastically reduces the number of physical qubits needed per logical qubit, making the engineering of quantum systems much more feasible.

Dial described this development as a game changer, improving both efficiency and practicality, making quantum systems easier to build and test. The Gross code reduces the need for large, cumbersome arrays of qubits, streamlining the path toward more powerful quantum computers.

Looking ahead, IBM’s roadmap outlines ambitious goals, including building a fully error-corrected system with 200 logical qubits by 2029. Dial stressed the importance of flexibility in the roadmap, acknowledging that the path to these goals could shift but would still lead to the achievement of quantum milestones.

The company’s commitment to these advancements reflects the dedication of the quantum team, many of whom have been working on the project for over a decade.

Despite the excitement and the challenges that remain, IBM’s vision for the future of quantum computing is clear: building the world’s first useful quantum computers.

The company’s ongoing work in quantum computing continues to capture imaginations, with significant steps being taken towards making these systems a reality in the near future.

Dutch researchers to face new security screenings

The Dutch government has proposed new legislation requiring background checks for thousands of researchers working with sensitive technologies. The plan, announced by Education Minister Eppo Bruins, aims to block foreign intelligence from accessing high-risk scientific work.

Around 8,000 people a year, including Dutch citizens, would undergo screenings involving criminal records, work history, and possible links to hostile regimes.

Intelligence services would support the process, which targets sectors like AI, quantum computing, and biotech.

Universities worry the checks may deter global talent due to delays and bureaucracy. Critics also highlight a loophole: screenings occur only once, meaning researchers could still be approached by foreign governments after being cleared.

While other countries are introducing similar measures, the Netherlands will attempt to avoid unnecessary delays. Officials admit, however, that no system can eliminate all risks.

Scientists achieve breakthrough in quantum computing stability

A new study by researchers from the University of Oxford, Delft University of Technology, Eindhoven University of Technology, and Quantum Machines has made a major step forward in quantum computing.

The team has found a way to make Majorana zero modes (MZMs)—special particles crucial for quantum computers—far more stable, bringing us closer to building error-free, scalable machines.

Quantum computers are incredibly powerful but face a key challenge: their basic units, qubits, are highly fragile and easily disrupted by environmental noise.

MZMs have long been seen as a potential solution because they are predicted to resist such disturbances, but stabilising them for practical use has been difficult until now.

The researchers created a structure called a three-site Kitaev chain, which is a simplified version of a topological superconductor.

By using quantum dots to trap electrons and connecting them with superconducting wires, they created a stable ‘sweet spot’ where MZMs could be farther apart, reducing interference and enhancing their stability.

Lead author Dr. Greg Mazur believes this breakthrough shows that it is possible to keep MZMs stable as quantum systems grow. With further research, the team aims to build longer chains to improve stability even more, potentially opening the door to reliable, next-generation quantum materials and devices.
