Recently, I have been analyzing the industrial chain ecosystem of the quantum computing sector and found that the participants in this field are much more numerous than expected. From hardware to software, from infrastructure to application deployment, the entire industry chain is already quite complete.

First, let's talk about complete machines and system platforms. GuoDun Quantum has a strong hold on the superconducting route, and its cloud services are now available worldwide. China Great Wall is investing heavily in ion trap research and development, already working on cryptographic integration. Sugon is exploring hybrid computing strategies, and the Quafu system has been online for some time.

Looking further down at the hardware layer, each company is deeply cultivating in their respective niche fields. FiberHome Technologies is working on single-photon sources to support projects like Jiuzhang. Western Superconducting provides niobium-titanium wire, which is used in Zuchongzhi’s superconducting circuits. Fuxin Technology’s dilution refrigeration solutions significantly reduce costs. Tengjing Technology specializes in interferometers and optical customization, with high technical barriers. Huagong Tech’s quantum dot chips are a unique approach in the laser field. Tianfu Communications supplies precision optical links and quantum modules.

At the chip and control system level, aerospace electronics’ control terminals and low-temperature integration solutions are very prominent in this round of competition. UCAS Guochuang’s scheduling framework and financial algorithm support are also quite good. Higuang Information is working on classical co-processing and quantum interface collaboration—an interesting approach that essentially reserves access channels for quantum computing.

On the software and algorithm side, China Information Technology has already implemented quantum encryption cases with banks, indicating market recognition. Kingdee focuses on financial modeling and trading optimization, while Neusoft Group combines medical simulation with quantum AI.

Quantum communication is resonating with quantum computing. Hengtong Optoelectronics is deploying in star-ground integrated and submarine links, with Zhongtian Technology’s quantum fiber becoming a main backbone. Shengyang Technology is working on low-orbit terminals, which also need to be compatible with Tainong.

In terms of infrastructure support, Kehua Data’s ultra-cold power supply solution can maintain a stable -273°C, which is crucial for quantum system operation. InVik is a liquid cooling expert, responsible for temperature control in quantum data centers.

On the industry investment and ecosystem level, Zhejiang Orient has a stake in GuoDun Quantum, clearly aiming for ecosystem layout. Demei Chemical holds shares in Benyuan Quantum, which is also preparing for an IPO.

Extending outward, China Mobile is developing quantum cloud networks and computing power scheduling; China Telecom has launched China Telecom Quantum, which is state-owned and controlled; China Unicom is active in secure dedicated lines and pilot cities. Inspur’s AI servers now support quantum access interfaces. Unisoc is working on chips and security foundations. Zhuoying Technology manufactures terminals and quantum modules. Suzhou Keda combines video security with quantum encryption. Jidai Zhengyuan focuses on identity authentication and quantum-resistant upgrades.

Looking at this entire picture, the quantum computing industry has never been isolated; it is deeply intertwined with traditional IT, communications, finance, and other fields. Each company specializes in its own niche, forming a tightly integrated industrial ecosystem. This also explains why this sector attracts so many participants—not just a simple technological competition, but an ecosystem competition.

Honestly, this observation is just a personal summary based on current information. Specific investment decisions still require thorough research. The market changes rapidly, and industry layouts are continuously evolving. The rankings of participants today may shift within half a year.
