SpinQ Raises $147 Million Series D as China's Quantum Computing Sector Accelerates Its Own Path

[IronFist66]

SpinQ, a Chinese quantum computing company headquartered in Shenzhen, announced on June 30 the completion of a RMB 1 billion Series D funding round, approximately $147 million USD, bringing its total funding over the past six months to RMB 2 billion, around $294 million. The round was backed by CICC Capital, Shenzhen TopoScend Capital, Shanghai Semiconductor Industry Investment, AVIC Honghua and Shanghai SEARI Private Equity Investment Management, a lineup of institutional and defence-adjacent investors that reflects the strategic rather than purely commercial lens through which China is approaching quantum infrastructure.

SpinQ has been quietly building one of the most commercially distributed quantum computing operations in the world. Its products and services reach more than 40 countries and regions across five continents, serving over 200 universities, research institutions and industry partners. The company completed China's first overseas delivery of a superconducting quantum chip in 2023, China's first overseas delivery of a complete superconducting quantum computer in 2024, and began batch deliveries of its Ursa Major superconducting quantum computing systems in 2025. The new funding will accelerate fault-tolerant quantum computer development, upgrade core manufacturing, and expand the global ecosystem further.

The Shenzhen foundry now covers chip design, process development, fabrication, packaging and testing in a vertically integrated operation that has completed tape-out, packaging and validation for 25-qubit and 103-qubit superconducting chips. SpinQ is pursuing both theoretical error correction advances, with cascaded quantum Hamming code decoding research accepted at QCE 2026, and experimental hardware targets including validation of distance-3 surface-code quantum error correction by end of 2026. The company is also exploring Quantum plus AI and quantum-supercomputing convergence, envisioning QPUs, CPUs and GPUs operating together in heterogeneous computing infrastructure.

RMB 2 billion in six months from primarily institutional and defence-adjacent investors is the signal that China is treating quantum computing as strategic infrastructure rather than a technology investment. The investor composition matters as much as the amount

Products reaching more than 40 countries from a Chinese quantum company is the internationalisation story that gets far less coverage than the US-centric quantum narrative. SpinQ has been quietly building a global commercial operation while the US sector has been mostly focused on domestic deployment

A vertically integrated operation covering chip design through fabrication through packaging in one Shenzhen facility is the manufacturing approach that could give SpinQ a cost advantage if superconducting quantum computing scales. Owning the stack reduces dependencies in exactly the ways that export controls on advanced components are designed to create

The 200-plus universities and research institutions being served is the ecosystem-building strategy that pays off over decades rather than quarters. Training the next generation of quantum engineers on your hardware is a long-term market development move that IBM used to great effect in classical computing

Distance-3 surface code validation being a 2026 target is specific enough to be trackable. If SpinQ delivers on that timeline it will have demonstrated genuine progress on one of the core milestones the entire quantum error correction field is working toward simultaneously

The Quantum plus AI framing being central to SpinQ's strategic direction mirrors what every US and European quantum company is also pursuing. The convergence narrative is universal even as the specific technical and commercial implementations differ significantly

The $294 million in six months landing the same week as the US quantum executive orders and multiple Western quantum IPOs illustrates the parallel development dynamic that has come to define technology investment in 2026. The quantum race is genuinely global and genuinely competitive
