Brazil tests quantum-secure communication over Recife fibre network

Researchers in Brazil have developed the Recife Quantum Network, a quantum key distribution system that uses inactive optical fibre already installed in the city’s urban infrastructure to test secure communications outside a laboratory setting.

The project, led by Professor Daniel Felinto at the Federal University of Pernambuco, connects university departments through dark fibre and uses quantum key distribution to protect information exchange.

Quantum key distribution relies on quantum properties that make interception detectable: any attempt to observe or copy the security key disrupts the quantum state, alerts the system and prevents secure key exchange.

The work has grown into a broader institutional effort through the Institute of Quantum Technologies, known as Quanta, based at the university’s ParqueTec. Researchers from the Federal Rural University of Pernambuco are also involved. The initiative received recognition through the 2025 Finep Innovation Award in the Northeast Region, in the research and development infrastructure category.

Initial tests over 7 kilometres have been completed, and the team now aims to expand the Recife quantum network to 40 kilometres with support from development institutions linked to Brazil’s Ministry of Science, Technology and Innovation. The project has also received support from the ministry through the National Education and Research Network and its Point of Presence in Pernambuco.

The initiative is presented as a step towards applying quantum key distribution-based secure communications to strategic cybersecurity needs, including defence and financial systems. Its use of existing telecommunications infrastructure is significant because it suggests that quantum-secure communication systems can be tested in urban environments without requiring entirely new fibre deployment.

Why does it matter?

Quantum key distribution is being explored as a way to protect sensitive communications against future threats, including advances in computing that could weaken current encryption methods. The Recife project is significant because it moves testing beyond laboratory conditions and into existing urban fibre infrastructure, which is a practical requirement for any wider deployment of quantum-secure networks.

For Brazil, the project also links cybersecurity with national research capacity, regional innovation and digital infrastructure development, showing how quantum technologies are beginning to move from academic experimentation towards applied communications security.

OSCE chairpersonship opens Geneva conference on AI and quantum risks

The Swiss OSCE Chairpersonship has opened a high-level conference in Geneva on how emerging technologies are affecting security, international governance, and co-operation across the OSCE region.

The two-day event, titled ‘Anticipating technologies – for a safe and humane future’, brings together about 200 participants from OSCE participating States and Partners for Co-operation, alongside representatives from international organisations, academia, the private sector, and civil society.

The conference focuses on the security implications of rapid technological change, including AI and quantum technologies. The discussions are intended to examine how anticipation, dialogue, and cooperation can help reduce misunderstandings, build trust, and strengthen security in a fast-changing technological environment.

Opening the conference, OSCE Chairman-in-Office and Swiss Federal Councillor Ignazio Cassis said: ‘Technology will not wait for us. Geopolitics will not slow down. If we want to remain relevant, we must anticipate – not react. This is the responsibility we share across the OSCE region. The OSCE still offers something rare: a space where adversaries can speak, where differences can be managed, and where common ground can still be built.’

The organisation’s Secretary General, Feridun H. Sinirlioğlu, also stressed the need for dialogue as emerging technologies evolve faster than governance frameworks. He said: ‘Today, emerging technologies are evolving faster than the frameworks that govern them. This creates a widening gap between what technology can do and how we manage it. This gap must be addressed through dialogue – our most important stabilizing force in uncertain times – and this is where the OSCE has a vital role to play.’

The programme includes discussions on anticipating technological change and its geopolitical impact, water and energy security in the digital age, and the role of AI in early warning and conflict prevention. The conference also highlights Geneva’s role as a meeting point for science and diplomacy, including through institutions such as CERN, the Geneva Science and Diplomacy Anticipator, and the Open Quantum Institute.

The event forms part of the Chairpersonship’s priority to connect scientific and technological anticipation with policy action. It is the second of four international conferences Switzerland is hosting under its chairpersonship, ahead of the OSCE Ministerial Council meeting in Lugano in December.

UNESCO report warns over global quantum research inequality

According to UNESCO, the unequal access to quantum research infrastructure risks widening global scientific and technological divides, with nearly one in three researchers worldwide still lacking access to quantum research facilities despite rapid growth in investment and interest in the field.

The findings come from The Quantum Moment: A Global Report, Outcomes of the International Year of Quantum Science and Technology, which analysed more than 1,300 quantum science events across 83 countries and included a global survey of 590 experts in 81 countries.

The report highlights major regional disparities, with Europe and North America hosting 7 times as many quantum-related events per country as Africa.

More than 150 countries still lack a national quantum strategy, even though global public and private investment in quantum science and technology reached $55.7 billion by mid-2025, according to UNESCO.

The organisation also points to a persistent gender gap, noting that while women account for a much larger share of early-career participants, they make up only around 16% of senior researchers and 12% of leadership roles in quantum fields.

UNESCO says quantum technologies could transform areas including healthcare, computing, cybersecurity, and climate modelling. To address infrastructure inequality, it has launched the Global Quantum Initiative and expanded programmes that give researchers from developing economies remote access to advanced quantum computing systems.

Canada moves to strengthen photonic semiconductor and AI capabilities

The Government of Canada has announced plans to spin off the National Research Council of Canada’s Canadian Photonics Fabrication Centre into a commercially operated entity to expand domestic semiconductor manufacturing and strengthen the country’s AI infrastructure.

The initiative forms part of Ottawa’s broader strategy to reinforce technological sovereignty and reduce dependence on foreign supply chains in critical technologies. Located in Ottawa, the Canadian Photonics Fabrication Centre is currently North America’s only end-to-end pure-play compound semiconductor facility and has supported photonics development for more than two decades through wafer design, fabrication, and testing services.

Minister of Industry and Minister responsible for Canada Economic Development for Quebec Regions Mélanie Joly said the spin-off is intended to attract private-sector investment, support Canadian innovation, and expand the country’s role in advanced manufacturing sectors, including defence, aerospace, automotive technologies, and AI.

The government also links the initiative to growing global demand for AI computing infrastructure, where photonic semiconductors are increasingly seen as important for improving energy efficiency, heat management, and data-transfer performance in large-scale data centres. Ottawa says the future commercial entity will remain anchored in Canada while helping domestic firms scale photonic and quantum technologies.

The expected result is a stronger Canadian supply chain for advanced semiconductor manufacturing and better support for fast-growing small and medium-sized enterprises working on AI and quantum systems. In that sense, the move is less about volume chip production and more about securing a specialised domestic capability in a strategically important part of the semiconductor stack. This final sentence is an inference based on the government’s framing of CPFC’s role and Canada’s wider AI and photonics strategy.

Quantum computing gains stability boost from NVIDIA error correction model

NVIDIA has strengthened its position in the emerging quantum computing sector through a new family of AI models designed to improve calibration and error correction in quantum systems. Rather than building its own quantum processing hardware, the company continues to focus on hybrid computing architectures that combine classical GPUs with quantum processors.

The new system reportedly improves quantum error correction decoding by up to 2.5 times in speed and three times in accuracy, addressing one of the most persistent barriers to scalable quantum computing. High error rates have long limited the practical deployment of quantum systems, making stability and fast correction central challenges for the industry.

NVIDIA has also expanded tools such as NVQLink and CUDA-Q, which allow quantum systems to integrate more directly with its existing GPU infrastructure. Together, these tools support workloads that can be distributed across classical and quantum environments, reinforcing NVIDIA’s role as a foundational infrastructure provider rather than a direct builder of quantum hardware.

The strategy positions NVIDIA to benefit regardless of how quantum computing develops. Whether hybrid systems become the dominant model or classical GPUs remain the primary computational layer for quantum processors, NVIDIA aims to remain embedded in the infrastructure stack that supports future quantum workloads.
