The Quantum Competition

Assessing U.S.–China leadership in quantum information science, engineering, and technology — and who is positioned to win the decade ahead.

The United States maintains a slight lead in quantum — but that lead is eroding as China executes a coordinated, state-backed strategy across research, industry, talent, and infrastructure.

Quantum information science, engineering, and technology (QISET) is emerging as a defining battleground in the U.S.–China technology competition. There may be no single moment of victory or defeat — only gradual shifts that reshape the balance of power as each nation secures an edge in quantum sensing, computing, networking, and materials. The country that leads in deploying practical quantum systems will gain enduring economic and national security advantages.

Because these systems are interconnected and tightly coupled in their development, this assessment evaluates the quantum portfolio under a single, unified lens rather than scoring each subfield in isolation.

Across the five dimensions of the SCSP Tech Scorecard, the United States currently maintains a slight overall lead — driven by strengths in innovation, software, private capital, and key elements of the supply chain. But that lead is narrowing as China integrates research, industrial policy, talent development, and infrastructure deployment into a unified national effort.

Looking ahead, the competition will hinge on three factors: how fast technologies move from the lab to the field, the ability to sustain investment through inevitable slow periods, and how effectively the United States can leverage alliances to build a resilient quantum ecosystem. Leadership will go not to the nation with the most scientific breakthroughs, but to the one that can produce operational quantum systems at scale.

Measuring the Balance of Power

The SCSP Tech Scorecard evaluates national competitiveness across five distinct categories of positional advantage. On a 1–5 scale, the United States leads four of five dimensions, while China’s coordinated state strategy gives it a decisive edge in national leverage.

Innovation Leadership

The United States retains a meaningful lead in quantum innovation, but that edge is diminishing. Researchers at American institutions account for 35% of the most-cited quantum papers — a share that has held steady — while China’s share has doubled to roughly 23%. The U.S. dominates error correction and simulation software, yet China is pulling ahead in advanced materials and closing the gap in algorithms and patents.

Industrial Capacity

The United States is ahead, but China is cutting costs. America holds structural advantages in the supply of critical inputs — like Helium-3 — and high-end specialized equipment such as dilution refrigerators and high-value lasers. China is compressing the cost of production, localizing its supply chain, and aligning fabrication capacity with aggressive regional subsidies.

Market Ecosystem

China is catching up to the U.S. private sector. The American market is powered by private capital — $5.3 billion in private quantum investment as of 2024 — and a dominant global software and developer base. China relies on a state-led model in which the government absorbs risk and drives deployment at scale, particularly in quantum networking.

Talent Pipeline

While the United States leads, its long-term advantage is uncertain. America benefits from an open university system and attracts a large share of international doctoral talent, with 61 institutions offering dedicated quantum information science and engineering programs. China’s advantage lies in the sheer scale of its STEM PhD output and a vertically integrated pipeline that co-locates universities with industrial hubs.

National Leverage

China’s strength is its government support for QISET. A centralized, multi-decade strategy embedded in its Five-Year Plans lets China mobilize public resources at scale. The U.S. approach is decentralized and market-driven, leaving it exposed to inconsistent funding from annual budget cycles and expiring legislation such as the National Quantum
