Guest Post by Dr. David Gunnarsson
After more than four decades of development, quantum computing is on the brink of its public and business breakthrough. We also see an increase in public interest, with quantum computing discussed across society. While many call for scale in manufacturing and progress in innovation, there is one big obstacle to rapid quantum development: it needs clear business cases. Today, technical feasibility has been largely demonstrated, and companies are steadily scaling their systems, needed cryogenics can handle demand, and the supply chains are in a solid place. Yet the field is missing one critical trigger: a clearly defined, commercially viable use case: “quantum’s ChatGPT moment”, a single, unignorable demonstration of business value that forces everyone to pay attention. When this happens, the technology won’t need years to catch up, it will be ready from day one.
Over the past forty years, quantum computing has evolved from theory to the deployment of several hundred systems worldwide. The underlying hardware, once experimental, is now technically more robust. Cryogenic systems, which are essential for cooling most quantum modalities, can already support systems with thousands of qubits. Production lines are active. Supply chains are stable. I know from experience that the building blocks are in place. In practice, the infrastructure is no longer waiting for the science.
