Quantum Race Analysis: The US Maintains Leadership, but China is Closing In
The United States still holds a small but noticeable advantage over China in the field of quantum information science, engineering, and technology (QISET). However, as my calculations, based on data from the analytical organization Special Competitive Studies Project (SCSP), show, this gap is rapidly closing. If current trends continue, U.S. leadership could disappear within the next few years.
I analyzed the positions of the two countries across five key areas: innovation, industrial capacity, market ecosystem, talent pool, and government levers. The results show that the U.S. dominates in four of them, but China confidently surpasses its competitor in the last category thanks to its centralized strategy, strong government support, and long-term planning.
U.S. Strengths: Innovation and Ecosystem
American researchers continue to set the tone in the scientific sphere. They account for 35% of the most cited publications on quantum technologies in 2025. For comparison, China's share is 23%, although it has doubled over the past decade. The U.S. is particularly strong in quantum error correction: 55% of the most cited patents in this field are associated with American authors, while China has only 18%.
The U.S. software ecosystem is a separate factor of strength. Tools like IBM's Qiskit (over 450,000 downloads) and Google's Cirq have become global standards. China's counterpart, PyQPanda from Origin Quantum, has been downloaded just over 4,000 times. This is a colossal gap, demonstrating how deeply American technologies have penetrated global development.
The market also confirms U.S. leadership: private investment in the country's quantum sector reached approximately $5.3 billion by 2024. For comparison, similar data for China is less transparent, but in my estimation, significantly lower. The number of deployed quantum computers in the U.S. (from 39 to 73) also exceeds Chinese figures (15–18), although the latter number may be understated due to data opacity.
Where China is Closing the Gap: Materials, Algorithms, and Networks
China is demonstrating impressive progress in materials science, algorithms, and quantum networks. In the segment of advanced quantum materials, Chinese researchers contribute about 50% of the strongest publications — a direct result of coordinated work by universities, state laboratories, and national structures.
In the field of quantum algorithms, China has already overtaken the U.S. in patents by a ratio of approximately 5:2. Although American authors still dominate publications, their share has dropped from 40% to 30% over the past five years, while China's has grown to 20%.
China's most significant advantage is in quantum networks. The country has deployed a quantum key distribution (QKD) system with a total length of 6,277 miles over fiber optics. In the U.S., comparable projects are limited to regional test sites (124 miles in the Chicago Quantum Network, 98 miles at Brookhaven National Laboratory). The U.S. National Security Agency has not made QKD a priority, citing implementation challenges, but this leaves the field open for Chinese expansion.
Manufacturing and Talent: U.S. Vulnerabilities
The industrial aspect is one of the weakest points for the U.S. Building clean rooms for quantum equipment in the States costs $800–1,000 per square foot, whereas in China it is about $150, with regional authorities subsidizing up to 30% of the costs. This creates a serious imbalance in the cost of scaling.
The talent issue is also concerning. Although 61 U.S. educational institutions offer programs in quantum sciences, China graduates over 50% more Ph.D.s in STEM fields annually. Since 2000, the growth in Chinese doctoral output has tripled that of the U.S. Meanwhile, the American system remains open to foreign researchers (about half of physics doctorates are awarded to non-residents), creating a dependence on global talent mobility.
Government Funding: China Leads
SCSP estimates Chinese government funding for quantum technologies at approximately $15 billion by the end of 2024. For comparison, U.S. investments over the past seven years total about $6 billion. The Chinese model, based on state laboratories and long-term plans, is clearly more aggressive financially. However, the American decentralized system, combining universities, startups, and giants like IBM and Google, retains flexibility.
My analysis shows: neither model is unequivocally better. The outcome of the race will be determined not by the amount of money or patents, but by the ability to translate laboratory breakthroughs into scalable, reliable, and commercially viable systems. The U.S. currently leads thanks to its innovation ecosystem, but China, with its resources and strategic planning, could overtake its competitor within the next 3–5 years if Washington does not accelerate investments in industry and talent.
