As classical computing approaches its physical limits, quantum technology has become the next great frontier, and Japan and China are leading Asia’s charge toward this new computing era.
Key takeaways China is rapidly scaling its quantum ecosystem through state-backed funding, research hubs like Hefei, and breakthroughs such as the 105-qubit Zuchongzhi 3.0 processor.Japan is advancing with precision and reliability, led by institutions like RIKEN and NICT, emphasizing domestic sourcing and long-term stability.Both nations view quantum computing as strategic to technological sovereignty, setting the stage for Asia to lead the next global computing revolution.
Both countries are combining public investment, academic research, and private innovation to secure a foothold in a field expected to reshape industries from finance to defense.
How China Is Preparing for the Next Frontier of Computing?
In China, the government’s long-term vision is to dominate what it calls “hard tech,” including semiconductors, artificial intelligence, and quantum computing.
The city of Hefei in Anhui Province has emerged as the heart of this effort. It hosts the University of Science and Technology of China (USTC), QuantumCTek, and more than 70 related enterprises, forming a full quantum industry chain that covers computation, communication, and measurement.
In 2025, Chinese scientists unveiled Zuchongzhi 3.0, a 105-qubit superconducting quantum computer that demonstrated advantages over traditional supercomputers in select tasks. Meanwhile, companies like SpinQ and Boson Quantum Technology are developing commercial hardware and photonic computing platforms.
To sustain momentum, Beijing launched a ¥1 trillion (US$138 billion) national venture fund this year to back deep-tech startups and reinforce China’s self-reliance in strategic technologies.
Japan and the RIKEN Initiative
Japan, in contrast, is pursuing a more measured but highly coordinated approach, focused on precision, reliability, and domestic sourcing.
The RIKEN Center for Quantum Computing (RQC) and the National Institute of Information and Communications Technology (NICT) anchor its ecosystem, with collaborations spanning superconducting, photonic, and cold-atom research. Industry partners like Fujitsu and NTT have already introduced cloud-based quantum computers built largely from Japanese-made components.
Tokyo’s Quantum Technology Innovation Strategy seeks to link academia, industry, and government while maintaining tight export controls on sensitive quantum hardware. Japan’s approach mirrors its broader industrial philosophy: incremental progress with a focus on quality, error correction, and long-term reliability.
Both nations see quantum computing as essential to technological sovereignty and future competitiveness. While China’s model emphasizes rapid scaling and integration with real-world applications, such as quantum communication networks and encrypted finance , Japan’s model prizes controlled innovation and precision engineering.
The stakes are high. Mastering quantum computing could transform global power dynamics, enabling breakthroughs in materials science, drug discovery, and cybersecurity. Whether through China’s scale or Japan’s meticulous engineering, Asia’s two technological giants are now defining what the quantum age will look like, and who will lead it.
