In an interview published by The Quantum Insider on October 3, 2026, 55North general partner Helmut Katzgraber argued that quantum computing’s more promising near- to medium-term uses lie in simulating materials, chemicals and pharmaceutical compounds, not optimization. He described optimization as an area where classical computing is likely to outperform quantum devices for the foreseeable future; no commercial advantage or deployment timeline was established in the interview.
Helmut Katzgraber, a general partner at quantum-focused venture fund 55North and a former quantum leader at AWS, says near- to medium-term quantum computing is more likely to find useful applications in simulating materials, chemicals and pharmaceuticals than in optimization. In an interview published by The Quantum Insider on October 3, 2026, he said classical computing is likely to outperform quantum devices on optimization for the foreseeable future, while presenting quantum simulation as a potential route to problems that are difficult for classical computers.
Katzgraber grounded his view in the type of computation he believes quantum machines are suited to perform: quantum-mechanical simulation. He pointed to strongly correlated systems, including battery materials, organic LEDs and some medications involving metal-organic complexes, as examples where classical computing can struggle. He said quantum technology could bring value in these areas, but framed that prospect as an expectation for the future, not as a demonstrated commercial result.
The interview also referred to a recently published paper reporting a material simulation on a neutral-atom quantum machine. Katzgraber described that research as an example of the workload he sees as promising. The interview did not provide the paper’s title, performance measures, or evidence that the machine outperformed classical methods, so the reference alone does not establish a practical quantum advantage.
On investment, Katzgraber said 55North sees opportunities beyond quantum processors. He cited refrigeration and software for computing error-correction models as enabling technologies that may serve multiple hardware approaches. He also discussed the shift from physical to logical qubits and the possibility that some companies could produce returns on venture-fund timelines, while presenting longer-term quantum applications as part of the fund’s investment horizon.
Where Quantum May Find Early Uses
Katzgraber’s distinction matters because it challenges the tendency to treat quantum computing as a general-purpose tool that should improve any difficult computation. His argument is narrower: a quantum device may be most relevant when the problem itself is governed by quantum mechanics. If that direction produces useful results, it could focus research and investment on chemistry and materials workloads rather than on optimization benchmarks that classical systems already handle effectively.
For businesses, the claim points toward possible long-term applications in areas such as battery development, advanced materials and drug research. But the interview does not show that quantum simulation has yet shortened development cycles or produced a commercial return. The distinction between a promising research direction and a usable product is central for investors and potential customers weighing costs, timelines and technical risk.
His comments also connect the application question to venture strategy. Investment in hardware-independent needs such as refrigeration and error-correction software may support several approaches to quantum computing, rather than relying on one machine type or one eventual application. That is Katzgraber’s investment perspective, not a guarantee that those companies will achieve returns.

From Quantum Research to Products
Katzgraber’s perspective reflects experience in academic research and industry. In the interview, he described leading a team of scientists at AWS that explored where quantum technologies might have real-world impact, including the goal of moving beyond toy problems toward customer-facing production settings. He also referred to earlier work at Microsoft and said his experience over several years helped him distinguish potential use cases from those likely to struggle.
He identified a separate challenge for Europe’s quantum sector. Katzgraber said Europe has strong scientific talent, universities and research support, but that the pipeline becomes less effective when research must be turned into products. The interview raised this as a commercialization gap, rather than offering comparative data on European, U.S. or Chinese companies or a detailed policy prescription.
The discussion covered several parts of the sector, including investment across the quantum technology stack and cloud versus on-premises deployment. Its central point, however, was the difference between applications that make use of quantum mechanics and optimization problems where classical computing may remain competitive.
“Use quantum where quantum reigns supreme, you know, in the quantum world.”

Evidence and Commercial Timelines
The interview presents Katzgraber’s informed assessment, but does not establish when a quantum simulation system will deliver a commercially useful advantage over classical computing. It gives no performance figures, cost comparisons, customer deployments or independent assessment of the neutral-atom result he referenced. The paper’s details and the precise limits of the reported simulation are also not included in the source material.
It is also unclear which materials or pharmaceutical tasks could be handled by near-term devices, what hardware scale and error rates would be required, and how those requirements would affect cost. Katzgraber described machine learning as an area where he was not ready to make a strong call. His prediction about optimization likewise concerns the foreseeable future and should not be read as a settled outcome for every problem or device.

The Tests That Could Validate This View
The next substantive evidence will come from research that reports what was simulated, how the quantum result was checked, and how its accuracy, runtime and resource demands compare with leading classical methods. For the areas Katzgraber named, practical demonstrations would also need to show relevance to specific materials, chemical systems or pharmaceutical questions, rather than only a small or illustrative calculation.
The interview does not announce a 55North investment, a product launch or a schedule for a commercial quantum application. Katzgraber’s case will therefore remain a forward-looking view until technical results and customer use provide clearer evidence. In parallel, the commercialization issue he raised for Europe will depend on whether research organizations and companies can turn laboratory work into products with identifiable users and sustainable business models.

Key Questions
What does Katzgraber think quantum computers may be used for first?
He sees quantum simulation for materials, chemicals and pharmaceuticals as a more promising near- to medium-term direction than optimization. He did not give a date for commercial applications.
Why does he favor simulation over optimization?
Katzgraber argues that quantum computers are best matched to problems that are quantum mechanical by nature. He said classical technologies are likely to outperform quantum devices on optimization for the foreseeable future.
Has a quantum computer already shown a commercial advantage in materials simulation?
The interview mentions a paper reporting a material simulation on a neutral-atom machine, but does not provide performance comparisons or evidence of commercial advantage. The reference should not be treated as proof that quantum computing has beaten classical methods.
What investment areas did Katzgraber highlight?
He cited enabling technologies such as refrigeration and software for calculating error-correction models, which may be relevant across different quantum hardware approaches. Those examples reflect his investment view, not a prediction of guaranteed returns.
What challenge did he identify for Europe’s quantum sector?
Katzgraber said Europe has strong talent and research support, but sees a weak link in turning laboratory ideas into products. The interview did not provide data quantifying that gap or propose a detailed remedy.
