Beyond the Qubit

Quantum computing has a hype problem.

Quantum computing has a hype problem. But the real challenge is much harder than most people think.


In Part 2 of this conversation, Frank Dekker continues his deep dive with Olivier Ezratty and gets into what real progress in quantum actually looks like. One of the clearest takeaways is that every step forward can create a new bottleneck. Solve one problem, and another appears right behind it.


This episode is for investors, founders, and anyone trying to understand why scaling quantum computing is so difficult. The challenge is not just adding more qubits. It is building a system that can handle noise, error correction, control complexity, and energy demands, while still producing something useful at a cost the market can bear.


That is what makes this conversation so valuable. Olivier brings a grounded perspective that goes beyond exciting narratives and focuses on what it really takes to make the whole system work.


💡 In this episode, we cover:

  • Why quantum computing has a hype problem

  • Why solving one problem often creates another

  • Why scaling quantum is not just about adding more qubits

  • How noise and control complexity slow real progress

  • Why error correction creates major system overhead

  • Why energy demands matter in the future of quantum computing

  • Why quantum is a full stack challenge across physics, engineering, software, control, and economics

  • Why the winners in quantum will be the teams that can make the whole system work
