Glasgow-based Quantcore has secured £2.5 million in seed funding to develop a sovereign supply chain for quantum hardware, as the UK seeks to strengthen domestic capacity in technologies linked to national security and economic competitiveness. The round was co-led by PXN Ventures, Blackfinch Ventures, and Scottish Enterprise, with additional backing from Quantum Exponential and STAC.
Founded in 2025 by Dr Jack Brennan, Dr Valentino Seferai, Wridhdhisom Karar, and Prof Martin Weides as a spin-out from the University of Glasgow, Quantcore designs, manufactures, and tests superconducting processors, resonators, and sensors that underpin quantum computers and advanced sensing systems.
Quantcore manufactures niobium-based components, a material that can operate at higher temperatures than aluminium, which is widely used by global competitors. By leveraging niobium, the company aims to help customers, including UK national laboratories, reduce energy consumption while improving the scalability and performance of quantum components.
Beyond computing, Quantcore’s quantum sensors support secure communications and high-precision medical imaging beyond the capabilities of classical technologies, with potential applications in neuroscience, early disease detection, secure infrastructure, and fundamental physics.
Highlighting the strategic implications, Quantcore CEO and co-founder Dr Jack Brennan said quantum computing’s code-breaking potential makes domestic manufacturing increasingly important, arguing the UK must build sovereign capability as classical computing approaches its limits.
The investment comes amid geopolitical uncertainty and follows the UK government’s commitment to invest £670 million in quantum computing as part of its 10-year modern industrial strategy.
Following the funding, Quantcore plans to expand its team with new engineering roles across design, manufacturing, and cryogenic testing, alongside commercial hires.
