Press release – SpinQ, a leading quantum computing company in China, has completed a RMB 1 billion Series D financing round, bringing its total funding raised over the past six months to RMB 2 billion.
The round was backed by a group of prominent institutional and industrial investors, including CICC Capital, Shenzhen TopoScend Capital, Shanghai Semiconductor Industry Investment, AVIC Honghua, and Shanghai SEARI Private Equity Investment Management, among others, with continued participation from existing shareholders.
The new funding will be used to accelerate SpinQ‘s full-stack development of fault-tolerant general-purpose quantum computers, upgrade core manufacturing processes, and expand its global ecosystem. The company said the investment will further strengthen its capabilities in quantum error correction, hardware-software integration, and large-scale commercialization.
SpinQ is also expanding its technology exploration into the convergence of quantum computing, supercomputing, and intelligent computing, as well as Quantum + AI. The company believes these directions could help shape next-generation heterogeneous computing infrastructure, enabling QPUs, CPUs, and GPUs to work together more effectively, while using AI to accelerate progress in quantum hardware, error correction, and real-world applications.
As the global quantum computing industry moves beyond a singular focus on qubit count, competition is increasingly shifting toward system stability, error correction, and engineering readiness. SpinQ has made fault-tolerant quantum computing a strategic priority, advancing both theoretical research and experimental development. The company’s research on cascaded quantum Hamming code decoding has been accepted by QCE 2026, while its hardware team is working toward completing validation of d=3 surface-code quantum error correction in 2026.
On the hardware side, SpinQ has established its own superconducting quantum chip R&D and pilot production line in Shenzhen, covering chip design, process development, fabrication, packaging, and testing. The company has completed tape-out, packaging, and validation for its new-generation 25-qubit and 103-qubit superconducting quantum chips, further strengthening its end-to-end capabilities across key technologies and manufacturing processes.
SpinQ has also built a full-stack technology platform spanning quantum chip design, quantum EDA software, control systems, full-system manufacturing, cloud services, and quantum algorithm applications. According to the company, this integrated approach provides a strong foundation for the system-level optimization required to achieve fault-tolerant quantum computing.
The company continues to expand its global commercial footprint. In 2023, SpinQ completed China’s first overseas delivery of a superconducting quantum chip. In 2024, it achieved China’s first overseas delivery of a complete superconducting quantum computer. In 2025, the company began batch deliveries of its“Ursa Major” superconducting quantum computing systems. SpinQ said its products and services now reach more than 40 countries and regions across five continents, serving more than 200 universities, research institutions, and industry partners.
“Quantum computing is a frontier technology that requires long-term commitment, sustained investment, and deep system-level engineering capabilities,” said Dr. Xiang Jingen, Founder and CEO of SpinQ. “With this new round of funding, we will remain focused on our core goal of building fault-tolerant general-purpose quantum computers, while continuing to advance quantum error correction and key hardware and software technologies. We look forward to working with partners across industry and academia to unlock the long-term value of quantum computing.”
