St. Louis, Missouri – Dec. 9, 2025 – Belden Inc. (NYSE: BDC), a leading global provider of complete connection solutions, is proud to strengthen its commitment to advancing secure connectivity in the quantum-AI era by partnering with Quantum Security & Defence (QSECDEF), the global orchestrator of the quantum-secure supply chain. 

From manufacturing to healthcare, the challenges organizations are facing have become so complex, data-intensive and interconnected that they can no longer be addressed with traditional computing alone. This is accelerating the move toward quantum approaches to solve high-stakes, computationally intensive problems. 

To support the transition, QSECDEF unites quantum professionals, leaders, academics and engineers from around the world to develop procurement standards, certification frameworks and education initiatives. The organization’s mission is to prepare enterprises and their leaders for a smooth, secure transition into quantum networking. 

With its experienced team of network infrastructure and cybersecurity experts, Belden stands ready to help QSECDEF advance practical pathways for quantum-safe networking and critical system resilience. Belden’s trusted, resilient and futureproof network infrastructure solutions will be essential to support quantum technologies as they move from the research stage to real-world deployment at scale. 

“Belden’s reputation for engineering excellence and leadership in secure connectivity make it a natural fit for our mission,” says Quantum Security & Defence CEO Anna Beata Kalisz Hedegaard. “Together, we aim to accelerate the adoption of quantum-secure standards and empower enterprises to prepare for the next generation of quantum secure communications and network security.”

Recent work with the Chicago Quantum Exchange is just one example of how Belden is collaborating with leading industry partners to establish a strong foundation for quantum‑safe networking. This collaboration with QSECDEF will allow Belden to continue to expand its impact and support enterprises and critical infrastructure operators globally.

“Harnessing the benefits of quantum depends on secure, resilient networks that enterprises can trust,” says Belden Vice President, Emerging Technologies Vijay K. Vallala.  “We partnered with QSECDEF because of its unique focus on creating the frameworks that can be used to build quantum roadmaps. Together, we can help bring quantum-secure networking to operational environments.”
