When quantum technology works, the real problems begin

The quantum technology worked. Then the real problems started. In this episode, I continue my conversation with Ingrid Romijn from Falqon® Systems to explore what happens when deep tech moves from demonstration into real-world deployment. One of my biggest takeaways was that the hardest problems often appear after the technology works. For Falqon®, the challenge was no longer simply whether quantum key distribution works. The challenge became integration: how do you connect quantum security technology with existing infrastructure, telecom networks, fibre providers, and customer security systems? This episode is for investors, founders, and anyone trying to understand how deep-tech companies move from technology development to commercial adoption. Real customers create real constraints. Government deployments push reliability requirements. Telecom customers push deployability. Enterprise users demand visibility into performance and operations. That customer feedback loop is where companies mature. The strategic question is not only whether a technology works. It is:How quickly can each customer make the next deployment easier? 💡 In this episode, we cover:Why real-world deployment creates new bottlenecks after the technology worksWhat Falqon® Systems learned from customer deploymentsHow the Port of Rotterdam exposed integration challengesWhy quantum security needs to work with existing infrastructureHow customer requirements shaped the Quantum Domain ControllerWhy telecom customers care about deployability and operationsWhy early customers become part of the innovation engineHow field experience can become a long-term competitive advantage Chapters00:00 Why deployment creates new challenges01:27 The Port of Rotterdam customer lesson02:50 Integrating quantum keys into existing infrastructure12:16 Learning from early customer deployments15:13 Building the Quantum Domain Controller31:13 What customers need to trust the system34:00 Why customer feedback creates a competitive moat Share this episode with someone investing in or building in quantum, and subscribe or follow Beyond the Qubit for more conversations on quantum technology, markets, and investing. 📌 Disclaimer:This is not investment advice.This post is shared on a personal basis and I do not represent any company.
