Quantum Computing Gets Down to Business

Quantum computing is moving from a physics-led narrative to an infrastructure business judged by customer returns, operating costs, energy use and manufacturing capacity.

• Pasqal already has commercial use cases before fault-tolerant machines arrive: Crédit Agricole plans to put three years of portfolio and risk work into production, while projects involve Saudi Aramco, Los Alamos National Laboratory and USA Rare Earth.
• Beating classical computers requires roughly 100 to 200 logical qubits with error rates below one in a million, a threshold no system has yet reached; companies are therefore separating into infrastructure providers and frontier hardware developers.
• Scale economics will be decisive: some architectures could consume about 100 megawatts and occupy a football-stadium-sized footprint, whereas Pasqal reports power consumption of about 3.5 kilowatts without cryogenic cooling.
• Manufacturing partnerships may create durable advantages: Quobly went directly to STMicroelectronics, obtained exclusive production access and secured materials supply for the next decade, while Paragraf is seeking funding for a high-volume two-dimensional-materials foundry.
• Materials are presented as an overlooked opportunity because graphene components can add almost no heat to cryogenic systems and may create a feedback loop between quantum simulation, manufacturable materials and more efficient hardware.

Takeaway: Investors should assess quantum companies like other capital-intensive technology businesses, focusing on customer economics, energy and space requirements, manufacturing control and strategic autonomy rather than qubit counts alone; commercial progress is real, but the underlying physics remains unresolved.
