Helmut Katzgraber, a general partner at quantum-focused venture firm 55North and a former quantum leader at AWS, says near- to medium-term quantum computing is more promising for simulating materials, chemicals and pharmaceuticals than for optimization. His view is an assessment, not evidence that quantum systems have already outperformed classical computers on commercially useful tasks.
Helmut Katzgraber, a general partner at 55North and a former quantum leader at AWS, said simulating materials, chemicals and pharmaceuticals is a more promising near- to medium-term use for quantum computers than optimization. In an interview published by The Quantum Insider on October 3, he argued that quantum systems may be best suited to problems governed by quantum mechanics, while stressing that useful commercial advantage remains a future prospect.
Katzgraber said strongly correlated systems are among the candidate workloads where classical computing can struggle. He pointed to battery materials, organic LEDs and certain medications involving metal-organic complexes as examples for which quantum simulation could eventually prove valuable. He did not claim that current quantum devices have already established a practical advantage for these applications.
He was more cautious about other proposed uses. Katzgraber said machine learning remains too nascent for him to make a firm judgment, while predicting that classical methods will outperform quantum devices in optimization for the foreseeable future. Those views reflect his experience across research and industry, including work at AWS and Microsoft, as described in the interview.
The conversation also covered 55North’s investment outlook. Katzgraber said some opportunities could produce returns within a venture fund’s lifetime, including refrigeration and software for error-correction models, which he described as enabling technologies relevant across quantum approaches. The interview also discussed European competitiveness and the challenge of turning research into products, but the available source text does not provide detailed answers on every topic raised.
Why Simulation Leads the Case
The distinction matters because quantum investment and research priorities depend on which workloads may plausibly benefit from quantum hardware. Katzgraber’s argument is that simulation of quantum-scale systems is a more natural fit than optimization, where he expects established classical technologies to remain ahead for now. If that assessment proves out, it could shape where companies direct engineering effort and where investors look for nearer-term commercial activity.
His comments also draw a line between potential scientific value and demonstrated business value. A candidate problem is not the same as a verified quantum advantage, and a research result does not by itself establish a production-ready application. For readers tracking the field, the interview is a view from an experienced investor and researcher—not a report of a newly validated commercial breakthrough.

From Quantum Research to Products
Katzgraber’s comments come from an interview with Yuval Boger, published by The Quantum Insider on October 3, 2026. The source identifies Katzgraber as a general partner at 55North, a Denmark-based venture fund focused on quantum technologies, and notes his earlier leadership work at AWS. He also referred to experience at Microsoft and in academic research.
The discussion frames quantum computing as a field with different possible paths to impact. Katzgraber favors workloads that require quantum-mechanical simulation, while treating machine learning as unresolved and optimization as less promising in the near term. He also described a potential gap in Europe’s quantum ecosystem: strong research and talent, but difficulty moving ideas from laboratories into products. That is his assessment in the interview, rather than an independent comparison of regional performance.
“Use quantum where quantum reigns supreme, you know, in the quantum world.”

Advantage and Timing Remain Open
The interview does not establish that a quantum computer has already delivered a commercially useful advantage over classical computing for materials simulation. Katzgraber referred to a recent paper on a material simulated with a neutral-atom machine, but the source excerpt does not identify the paper, describe its methods or results, or show that it demonstrates practical superiority over classical approaches.
The timing of any usable advantage is also uncertain. Katzgraber described value as something quantum technologies may bring “down the road,” and the interview supplies no specific deployment date, performance threshold or customer case. His forecasts about optimization and the commercial outlook should be read as expert assessments, not settled conclusions.
The source text available for this report ends while the interview is discussing Europe’s path from laboratory research to products. It therefore does not provide Katzgraber’s full response on that subject, nor enough detail to assess how 55North evaluates particular companies, fund returns or deployment models.

Evidence Needed for Commercial Use
The next meaningful test of Katzgraber’s thesis will be whether quantum simulation research can show repeatable results on relevant materials or chemical problems and whether those results compare favorably with the best classical methods. That would require details about the workload, hardware, accuracy, computational cost and comparison baseline—information not supplied in the interview excerpt.
For investors and prospective users, the nearer-term question is whether enabling technologies such as refrigeration and error-correction software can support sustainable businesses before end-user quantum applications mature. The interview does not announce a new 55North investment, product launch or technical milestone. Further developments will depend on research results and companies’ ability to turn them into reliable products.

Key Questions
What quantum-computing applications does Katzgraber consider most promising?
He points to quantum simulation for materials, chemicals and pharmaceuticals, including some strongly correlated systems such as battery materials and organic LEDs. He describes these as potential applications, not established commercial successes.
Why is he skeptical about quantum optimization?
Katzgraber expects classical technologies to outperform quantum devices in optimization for the foreseeable future. The interview presents this as his assessment and does not provide comparative benchmark data.
Did the interview report a proven quantum advantage in materials simulation?
No. Katzgraber mentioned a recent paper involving simulation of a material on a neutral-atom machine, but the source excerpt does not give enough information to establish that the work demonstrated a practical advantage over classical computing.
What quantum-sector investments may have nearer-term returns?
Katzgraber cited enabling areas such as refrigeration and software for error-correction models. He said some technologies could produce returns within a venture fund’s lifetime, but did not provide specific forecasts or identify a new investment in the interview.
What did Katzgraber say about Europe’s position in quantum technology?
He said Europe has strong talent, education and research support, but described the path from laboratory ideas to marketable products as a weak point. That is his characterization in the interview, not an independently verified regional comparison.
