Imagine a world where hacking is virtually impossible, and your data is safeguarded by the unbreakable laws of physics. Sounds like science fiction, right? But this future is closer than you think, thanks to groundbreaking work in quantum computing security. A spin-out company from Lancaster University, Photarix, is at the forefront of this revolution, tackling one of the biggest hurdles in quantum encryption: creating a reliable source of single photons.
Quantum Key Distribution (QKD), a cutting-edge method for securing data, relies on these single photons to transmit encryption keys with unprecedented security. However, generating them efficiently has been a major challenge—until now. Photarix is developing Quantum Ring Single-Photon Light-Emitting Diodes (QR SPLEDs), a game-changing technology that promises to make QKD more practical and affordable.
Here’s the game-changer: QR SPLEDs can emit single photons at the precise wavelengths needed for fiber-optic networks, all in a compact, cost-effective design that operates at or near room temperature. And this is the part most people miss: this innovation could democratize quantum security, making it accessible not just to governments and corporations, but to everyday users too.
The story behind Photarix is just as inspiring as the technology itself. Founded by Dr. Gizem Acar Tekin, now CEO, the company emerged from her PhD research in quantum photonics at Lancaster University. Working alongside Professor Manus Hayne, now Chief Scientific Officer, Tekin’s journey has been fueled by support from prestigious programs like the European Commission’s Horizon 2020 and Innovate UK’s CyberASAP.
Photarix’s momentum hasn’t slowed since. As the first Lancaster University spin-out to join the NW CyberCom initiative, the company is helping to position the North West as a national leader in cybersecurity innovation. Jess Wenmouth, Head of Research Commercialisation at Lancaster University, praises Photarix as a “fantastic example of the strength of Lancaster University’s research ecosystem.”
But here’s where it gets controversial: While quantum encryption promises unparalleled security, it also raises questions about accessibility and ethical use. Will this technology only benefit the privileged few, or can it truly level the playing field? And what are the implications for privacy in an era of unhackable communication?
Photarix’s impact is already being recognized on a global stage. The UK Government’s Department for Science, Innovation and Technology has invited the company to showcase its work at the International Cyber Expo 2026 in London, where Dr. Acar Tekin will share insights into this transformative technology.
Speaking of global recognition, the EdTech Innovation Hub Awards (ETIH) 2026 are now open for entries, celebrating excellence in education technology worldwide. With a focus on workforce development, AI integration, and innovative learning solutions, the awards spotlight companies and individuals driving change across all stages of education.
From AI-driven assessment tools to digital platforms connecting learners with real-world outcomes, the ETIH Awards recognize measurable impact in K–12, higher education, and lifelong learning. Winners will be announced on 14 January 2026 as part of an online showcase, with all finalists featured in the inaugural ETIH print magazine, distributed at BETT 2026.
As we stand on the brink of a quantum revolution, Photarix and initiatives like the ETIH Awards remind us that innovation isn’t just about technology—it’s about shaping a future where security, education, and opportunity are accessible to all. But the question remains: Are we ready for the challenges and opportunities this future brings? Share your thoughts in the comments below—let’s spark a conversation!
