SpinQ: 1B RMB Funding & QEC 2026 Quantum Error Correction Breakthrough
2026.05.09 · Blog quantum computing news
The global quantum computing industry is transitioning from noisy intermediate-scale quantum (NISQ) experimentation to practical, fault-tolerant, and industrial-grade quantum systems. In 2026, Chinese full-stack quantum computing leader SpinQ Technology unveiled two landmark achievements: a nearly 1 billion RMB Series C funding round to scale superconducting quantum hardware, and a cutting-edge quantum error correction research breakthrough in collaboration with the Hong Kong University of Science and Technology (HKUST), which has been accepted by the authoritative QEC 2026 conference. These advances effectively solve core bottlenecks in quantum chip scaling and error suppression, laying a solid foundation for the commercial deployment of utility-scale quantum computing.
Introduction
Useful quantum computing relies on two core pillars: scalable high-qubit quantum hardware and reliable quantum error correction technology. For years, the global quantum sector has been hampered by unstable qubit performance, high error rates, and insufficient industrial production capacity. Different from most research-oriented quantum enterprises, SpinQ Technology adheres to a dual-driven development model of academic research and commercial industrialization. With the latest capital injection and technological innovations, the company is significantly narrowing the gap between laboratory quantum technology and real-world industrial applications, becoming a key driver of global quantum computing industrialization in 2026.
Nearly 1 Billion RMB Series C Funding Boosts Superconducting Quantum Industrialization
SpinQ Technology completed a landmark financing layout in the first half of 2026, gathering strong industrial and state-owned capital support to accelerate the large-scale iteration and production of superconducting quantum chips. The company finished a 600 million RMB Series C+ financing round on April 3, 2026, bringing the total Series C fundraising amount to nearly 1 billion RMB within just three months. This financing marks a key leap for SpinQ from laboratory research to large-scale industrial deployment.
The financing consortium covers top domestic investment institutions, with Glacier Capital acting as the exclusive strategic financial advisor. The new funds are fully targeted at the R&D of next-generation high-qubit superconducting quantum chips and the expansion of standardized industrial production lines. As early as January 2026, SpinQ completed the initial Series C financing of hundreds of millions of RMB, focusing on optimizing superconducting chip manufacturing processes, iterating quantum error correction protocols, and upgrading high-precision measurement and control hardware, with a clear strategic goal of developing 100-qubit industrial-grade quantum processors.

Breakthrough Quantum Error Correction Research Accepted by QEC 2026
Quantum error correction is the core technology to solve qubit instability and realize fault-tolerant quantum computing, and it is also the key to upgrading NISQ devices to large-scale reliable quantum computers. On April 23, 2026, SpinQ Technology’s joint research team with HKUST achieved an important technical breakthrough in this field. Their research paper on efficient quantum decoding algorithms was officially accepted for presentation at QEC 2026, the world’s top academic conference focusing on quantum error correction and fault-tolerant computing.
The paper titled Efficient high-threshold decoding for concatenated quantum Hamming codes with near-optimal effective distance proposes an innovative bidirectional hard-decision decoding framework, which effectively makes up for the technical defects of traditional one-way local decoding. The core technical performance improvements are summarized in the table below:

Different from conventional decoding technologies that only rely on local information for error judgment, the new bidirectional decoding algorithm innovatively uses high-level syndrome information to optimize low-level recovery decisions. It maintains near-optimal code distance scaling in multi-level concatenated quantum codes, which can significantly reduce the logical error rate of quantum systems. This research achievement not only solves the long-standing bottleneck of error accumulation in concatenated quantum codes but also reduces the physical qubit resources required for fault tolerance, providing a feasible low-overhead technical path for large-scale quantum computing.
Industry Significance and Future Outlook
The dual breakthroughs of financing and technology have established SpinQ’s important position in the global quantum computing industrialization process. While most quantum enterprises are still stuck in single technical route research or pure laboratory exploration, SpinQ has formed a closed-loop development model of "capital empowerment - hardware iteration - technological innovation - commercial landing". The stable revenue from educational NMR quantum devices supports the long-term R&D of high-end superconducting quantum systems, while cutting-edge error correction technologies continuously improve the reliability of industrial quantum hardware.
As the global quantum computing market is poised for explosive growth, SpinQ’s full-stack innovation capabilities will continue to drive the transformation of quantum technology from theoretical research to industrial practicality, helping the global quantum industry usher in the era of reliable and scalable utility computing.
