Figures on quantum technologies from published reports, grouped by topic. Each figure names its publisher, edition and the page or section it comes from, and appears only after an editor has checked it against the source. Reports often disagree: where several publishers give comparable figures, the range between them is shown, never an average.
Figures by topic
Investment
Private and venture investment in quantum companies and where it goes.
Range across reports: Investment in quantum companies, worldwide, 2025: from $4.9 billion (USD billion) (Quantum Economic Development Consortium (QED-C), managed by SRI International) to $10-$12 billion (USD billion) (IQM Quantum Computers), across 2 publishers. Their definitions differ; no average is given. Why do they differ?
Public funding, national strategies and programmes.
Range across reports: Public funding commitments for quantum, worldwide, cumulative, 2025: from an estimated USD 55.7 billion (OECD and European Patent Office) to an estimated $56.7 billion (USD billion) (Quantum Economic Development Consortium (QED-C), managed by SRI International), across 2 publishers. Their definitions differ; no average is given. Why do they differ?
Worldwide quantum computing, communication and sensing: investment, market, talent and patents.
