The rapid development of Quantum Computers poses a serious threat to classical encryption methods, which rely on the complexity of mathematical functions. Due to their enormous computational power, Quantum Computers can break currently used algorithms in a very short time. This is exactly where Quantum Communication comes in: it offers entirely new and secure ways of transmitting data. Quantum Key Distribution (QKD), which leverages the principles of Quantum Mechanics, enables secure key exchange and has proven to be a groundbreaking technology to counter the threat posed by Quantum Computers.

UK Research and Innovation has outlined how it will deploy a record £38.6 billion government settlement over four years, aligning funding to a single mission focused on advancing knowledge, improving lives, and driving UK economic growth. UKRI’s targeted investment explicitly labeled for “Digital and Technologies: Quantum Technologies” totals £1.013 billion over the spending review period (FY 2026–27 through FY 2029–30). The allocation prioritizes £14 billion for curiosity-driven research, £8 billion for targeted R&D addressing national and societal challenges, and £7 billion to support innovative companies in scaling and commercializing technologies, with remaining funds supporting cross-cutting skills and infrastructure. Covering financial years 2026–27 through 2029–30, the outcome-focused framework cannot be directly compared with previous UKRI budgets or historic sector and research council allocations.

Quantum technologies represent another major leap forward. With potential applications ranging from ultra-secure communications to enhanced sensing and faster decision-making, quantum solutions could transform cyber operations, targeting and information processing. The EDF is placing these technologies at the forefront of European defence innovation.

Quantum Corridor, in collaboration with Toshiba International Corporation and partners, today announced the successful demonstration of quantum-secured communication over a live metropolitan fiber network connecting Tier III data centers in Illinois and Indiana—an achievement that marks a critical step toward building a commercially scalable, quantum-safe internet for the United States.

New Zealand and South Korea have launched three joint quantum communication research projects aimed at enabling secure long-distance networks, compact hardware and cross-signal connectivity. One project is developing quantum repeaters using rare-earth quantum memories in photonic circuits to extend ultra-secure communication across cities and countries. Two additional projects focus on a chip-based quantum light source for affordable quantum key distribution and a signal interface that links light and microwave quantum systems.

PROJECT skQCI is part of the EuroQCI – a secure quantum communication infrastructure spanning the whole EU.

SpeQtral, Singapore's leading quantum communications company, in partnership with the UK Science and Technology Facilities Council's (STFC) RAL Space, announces the successful launch and deployment of the SpeQtre CubeSat aboard SpaceX's Transporter-15 mission. The spacecraft, containing SpeQtral's space-qualified entangled photon pair source and detector modules was deployed into sun-synchronous orbit on 28th November, 2025, marking a significant milestone for Singapore-UK space collaboration and quantum communications technology.

The Technology Innovation Institute (TII), the applied research arm of Abu Dhabi’s Advanced Technology Research Council (ATRC), and Honeywell have launched a joint initiative to develop quantum-secure satellite communication systems designed to protect sensitive information across global networks.

Roadrunner Venture Studios and Qunnect have jointly launched New Mexico’s first quantum network, designated ABQ-Net. This new network utilizes quantum key distribution (QKD) to secure data transmission via entangled photons, establishing a foundational infrastructure for quantum communication. The launch, announced November 19, 2025, signifies a key step in developing a secure communications ecosystem and positions New Mexico as an emerging hub for quantum technologies. ABQ-Net aims to provide a platform for testing and deploying advanced quantum technologies and applications.

The U.S. Department of Energy announced $625 million in funding to renew its five National Quantum Information Science Research Centers.
