Claim: SpinQ Completes $147M Series D Financing to Advance Fault-Tolerant Quantum Computing
Summarize this article with:
Series D Funding: SpinQ raises RMB 1 billion, bringing its total funding over the past six months to RMB 2 billion from a consortium of institutional and industrial investors.Technical Progress: Validation completed for new-generation 25-qubit and 103-qubit superconducting quantum chips, with d=3 surface-code quantum error correction validation targeted for 2026.Global Footprint: Quantum systems and services now deployed across more than 40 countries and regions, serving over 200 universities, research institutions, and industry partners.SpinQ Technology Inc., the Shenzhen-based quantum computing company, has closed a RMB 1 billion (€129 million / $147 million USD) Series D financing round. The round was backed by CICC Capital, Shenzhen TopoScend Capital, Shanghai Semiconductor Industry Investment, AVIC Honghua, Shanghai SEARI Private Equity Investment Management, and other institutional and industrial investors, with continued participation from existing shareholders. Total funding raised in the past six months now stands at RMB 2 billion. The capital will accelerate full-stack development of fault-tolerant quantum computing, upgrade core manufacturing processes, expand the global ecosystem, and strengthen capabilities in quantum error correction, hardware-software integration, and large-scale commercialization.SpinQ has completed tape-out, packaging, and validation for its new-generation 25-qubit and 103-qubit superconducting quantum chips. The hardware team is working toward completing validation of d=3 surface-code quantum error correction in 2026. Research on cascaded quantum Hamming code decoding has been accepted for QCE 2026. These milestones reflect the broader industry shift toward system stability, quantum error correction performance, and engineering readiness beyond raw qubit counts. The company’s Ursa Major superconducting quantum computing systems began batch deliveries in 2025.SpinQ operates its own superconducting quantum chip R&D and pilot production line in Shenzhen, encompassing chip design, process development, fabrication, packaging, and testing. Its integrated full-stack platform covers quantum chip design, quantum EDA software, control systems, full-system manufacturing, cloud services, and quantum algorithm applications. This end-to-end capability supports the system-level optimization required for fault-tolerant quantum computing.The funding will support expansion of SpinQ’s global ecosystem and large-scale commercialization. Products and services now reach more than 40 countries and regions across five continents and serve more than 200 universities, research institutions, and industry partners. Key milestones include China’s first overseas delivery of a superconducting quantum chip in 2023 and the first overseas delivery of a complete superconducting quantum computer in 2024. In 2026, SpinQ supported the launch of Kazakhstan’s first “Quantum AI” Teaching and Research Laboratory. 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. Dr. Xiang Jingen, Founder and CEO of SpinQ, said: “Quantum computing is a frontier technology that requires long-term commitment, sustained investment, and deep system-level engineering capabilities. 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.”Additional priorities include technology exploration at the intersection of quantum computing, supercomputing, and intelligent computing, as well as Quantum + AI applications. These initiatives target next-generation heterogeneous computing infrastructure in which QPUs, CPUs, and GPUs can operate together more effectively, with AI used to accelerate progress in quantum hardware, error correction, and practical applications.Find out more here.Editor’s Note: This report includes information derived from company statements and Chinese-language media coverage.
