Beyond the Qubit

What if one of the biggest winners in quantum is not the company building the qubits, but the one helping everyone understand what is going wrong inside them?

In this episode, I unpack the key learnings from my deep dive with Johannes Jobst, CEO of QuantaMap. The deeper I go into quantum computing, the more I think this industry will become obsessed with measurement. Most people focus on the race for better qubits, higher fidelity, and larger systems. But after this conversation, I am no longer sure that is the full story.

This episode is for investors, founders, and anyone trying to understand how the quantum value chain may evolve. One of the biggest bottlenecks may not just be building quantum chips. It may be inspection, metrology, defect detection, process supervision, and understanding the subtle material imperfections and microscopic noise sources that undermine coherence, repeatability, and yield.

That is what makes this conversation so important. In classical semiconductors, advanced manufacturing scaled because an entire ecosystem was built around measurement, validation, and process control. Quantum does not yet have that same mature inspection layer. If that becomes a core bottleneck, the companies that help the industry see, diagnose, and improve quantum systems may become just as important as the companies building the hardware itself.

💡 In this episode, we cover:
Why measurement may become one of the most important layers in quantum computing

Why quantum chip inspection is still an underbuilt part of the stack

How subtle material defects and microscopic noise sources affect performance

Why coherence, repeatability, and yield depend on better diagnostics

How the quantum industry may shift from building systems to validating and controlling them

Why inspection, metrology, and process supervision could become strategically valuable

What investors should learn from the semiconductor industry’s measurement ecosystem

Why quantum may become not just a computing revolution, but a measurement revolution

Could the real value in quantum sit above the hardware?Because after two hours with quantum founders, the real question is not only what they are building. It is also how that changes the value chain.In this episode, Henny Crauwels interviews me after my deep dive with ParityQC to unpack the biggest lessons from that conversation. One takeaway stood out: the most interesting quantum company may not be the one with the most qubits. It may be the one that helps everyone else get more out of their qubits.This episode is for investors, founders, and anyone trying to understand how quantum computing could evolve as a market. We look at why architecture matters, how ParityQC’s approach could reduce bottlenecks in today’s systems, and why enabling layers may matter so much in a market where it is still unclear which hardware path will win.That is what makes this format valuable. The deep dives explain the technology. The key learnings connect it back to markets, business models, strategy, and where value may actually accrue across the stack.

What if the company that captures the most value in quantum is the one that helps everyone else perform better?

In this episode, I go deeper with Magdalena Hauser and Wolfgang Lechner of ParityQC to explore a very different way of thinking about value in quantum computing. A lot of the discussion still centers on hardware alone: more qubits, better fidelity, bigger systems. But ParityQC is making a different bet, one built around architecture, IP, and enabling software.

This conversation is for investors, founders, and anyone trying to understand where value may really build across the quantum stack. We unpack ParityQC’s core idea of representing relative information instead of the information itself, why that could matter for connectivity and error correction, and why their business model looks closer to an architecture company than a full stack hardware player.

That is what makes this episode so interesting. It is not just about physics. It is about business model, defensibility, IP, and what it means to control a critical layer of the stack in a market where not every winner will own the full machine.

💡 In this episode, we cover:
How ParityQC’s parity transformation changes the way quantum information is represented

Why relative information could help with connectivity, programmability, and redundancy

How ParityQC thinks about error correction differently

Why the company licenses IP and enabling software instead of building full stack hardware

Why their model looks closer to ARM than a traditional quantum hardware company

How ParityQC monetizes through licensing and software

Why profitability matters so much in today’s quantum market

What investors should watch if they want to track whether the model is working

What if the real breakthrough in quantum computing is not just better qubits, but a better way to use them?

In this episode, I explore why architecture may be one of the most overlooked layers in quantum computing with Magdalena Hauser and Wolfgang Lechner of ParityQC. Their latest result, implementing a 52-qubit Quantum Fourier Transform on an IBM Quantum Heron processor, suggests that progress may not only come from hardware improvements, but also from smarter architecture and compilation.

This episode is for investors, founders, and anyone trying to understand where value may build across the quantum stack. If ParityQC is right, the winners in quantum may not only be the companies building the machines. They may also be the companies that make those machines more useful, more scalable, and more efficient.

That is what makes this conversation so interesting. It shifts the question from who has the best hardware to who has the best architecture for turning hardware into real performance.

💡 In this episode, we cover:
Why ParityQC believes architecture is a core layer of value in quantum computing

Why the Quantum Fourier Transform is such an important benchmark

How ParityQC and IBM reached a 52-qubit QFT result

Why this result is about more than hardware alone

How architecture and compilation can improve real quantum performance

Why ParityQC’s approach is designed to work across multiple hardware platforms

Why removing swaps matters in quantum computing

Why investors may need to look beyond hardware to understand where value will accrue

In Part 3 of this conversation, Frank Dekker reflects on one of the biggest takeaways from his discussion with Olivier Ezratty: great science alone does not create a winning quantum ecosystem. Europe has deep talent, strong research, and serious technical capability, but turning that into globally relevant companies is a different challenge.

This episode is for investors, founders, policymakers, and anyone trying to understand what it will really take for Europe to compete in quantum. The conversation goes beyond technology and looks at the harder questions around energy, coordination, ecosystem building, and long term strategy.

That is what makes Olivier’s perspective so valuable. He is not only trying to understand where quantum is going. He is trying to improve the odds that Europe builds something meaningful around it.

💡 In this episode, we cover:
Why strong quantum talent does not automatically create strong quantum companies

Why the Quantum Energy Initiative matters for the future economics of the industry

Why energy and power costs could shape who scales and who can deploy

Why ecosystem building takes more than great technology

How Olivier thinks about strengthening the French and European quantum landscape

Why Europe needs stronger links between research, capital, policy, and industry

Why coordination may matter as much as technical progress

What Europe needs most right now to improve its chances in quantum
