• The US-China technology rivalry is increasingly centered on quantum computing, with both nations treating the field as a strategic asset with profound economic and national security implications alongside AI and semiconductors. • China has deployed an estimated US$16 billion in public funding—roughly four times current US government investment—embedding quantum computing into its Five-Year Plan as one of seven frontier technologies through a highly centralized, state-led approach. • The US ecosystem remains decentralized, driven by over 40 companies, national laboratories, universities, and hyperscalers, with government support focused on funding, benchmarking, and validation rather than selecting national champions.

Liz Kendall announces £1bn funding to help design large-scale quantum computers for scientists, researchers, public sector and businessThe UK will not let quantum computing talent slip through its fingers and must learn lessons from US dominance of the AI race, the technology secretary has said, as the government announced a £1bn quantum funding pledge.Liz Kendall said the government hoped to retain homegrown quantum startups, engineers and researchers rather than lose them to competing countries, with the US stealing a march on its western rivals in AI.
