The future of data security and connectivity is rapidly taking shape, as quantum technology transitions from research labs to real-world deployment, with 2026 poised as a pivotal year for the UK’s ambitious goal of a world-class quantum network by 2035, according to recent analysis.
Quantum Networks: The UK’s Next Tech Frontier
The UK is making significant strides toward building a quantum ecosystem, but robust infrastructure is key.
- The UK aims to secure 15% of the global quantum technologies market and private equity investment by 2033.
- Progress in 2026 is crucial for achieving these ambitious goals.
- Building both quantum-ready and quantum-secure networks is paramount.
- Investment in quantum technologies is accelerating globally.
According to Gabriela Styf Sjoman, managing director of research and network strategy, the UK’s next phase of quantum progress hinges on building networks prepared for—and protected by—quantum technology. “As exciting and extraordinary as quantum computers, sensors and devices are – on their own, they are isolated,” Sjoman stated. “Their true value is unlocked only when they are connected – to each other, to users, to data, and to the wider digital ecosystem.”
The Need for Quantum Infrastructure
The emergence of quantum computing, coupled with rising investment and promising early applications, signals that quantum technology is no longer a distant possibility, but a defining technology of the coming decade. The UK has a unique opportunity to lead in this space, but success depends on a solid foundation.
Just as artificial intelligence relies on cloud infrastructure and electric vehicles require charging networks, quantum technologies demand networks that are both quantum-secure and quantum-ready. This infrastructure is the bedrock of the UK’s future quantum economy.
BT is positioning itself as a key player in delivering these networks, leveraging its position as the UK’s leading network provider. The company is actively developing quantum-secure networks utilizing technologies like Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and entanglement-based security to safeguard data against current and future threats.
Investment and Collaboration
As BT published its analysis, UK Research and Innovation (UKRI) was finalizing its £38.6 billion budget, with £1 billion earmarked for quantum technologies between 2026 and 2030. This substantial investment underscores the UK’s commitment to the field.
BT has already begun laying the groundwork for future quantum networks. In 2025, the company partnered with the University of Suffolk to build a research facility focused on optical space-to-ground communications, deemed essential for satellite-enabled quantum networks. BT has also developed intellectual property in quantum sensing and successfully trialed a quantum radio receiver.
Furthermore, UKRI has selected BT to lead Project Spectra, an initiative aimed at advancing quantum-enabled RF sensing and bolstering the UK’s sovereign capabilities on a global scale.
“Making quantum technologies is as critical as enabling, adopting and implementing them – and essential for UK leadership,” Sjoman emphasized. “The UK enters 2026 from a position of strength, with thriving startups, strong industrial players and world-class research. Now we need to accelerate adoption, and build deeper, more resilient supply chains. Government has a key role to play: stimulating demand, convening industry and users, and helping to turn breakthrough science into deployable solutions.”
