Insider Brief
- Taiyi Quantum reportedly raised 300 million yuan, or about $44 million, in a Pre-A funding round that underscores investor interest in China’s quantum computing sector.
- The Shanghai startup is led by Liu Hongbin, a former Microsoft Azure Quantum architect who reportedly worked on Microsoft’s collaboration with Atom Computing.
- Taiyi is developing a ytterbium-based neutral-atom quantum computer, an approach that uses laser-trapped atoms as qubits and may offer advantages in scaling, control and error detection.

Taiyi Quantum, based in Shanghai, announced the completion of a 300 million yuan — or about $44 million USD — Pre-A funding round, according to media and social media reports.
The round was led by investors including Gaorong Venture Capital and IDG Capital, who were joined by Huakong Fund, Yunqi Capital, Dachen Caizhi, Boyuan Capital, SAIC Financial Holdings, Hengxu Capital, Yarui Capital, Qifu Capital and various institutions and industries such as the Electronics Fund, Jiemian News is reporting.
The neutral atom quantum computing startup is led by Liu Hongbin, a former research scientists at Microsoft and ex-Principal Architect and Engineering Manager at Microsoft Azure Quantum. According to Hongbin’s LinkedIn profile, his accomplishments at Microsoft included the design of the full-stack quantum computing architecture, spanning quantum algorithms, error correction, classical-quantum hardware integration and developer APIs.
Hongbin reportedly worked on Microsoft‘s initiative with Atom Computing, which takes an optically-trapped neutral atom approach to quantum computers.
Taiyi uses a ytterbium-based neutral-atom approach, which means its quantum bits are encoded in individual ytterbium atoms held in place by laser light, rather than in fabricated solid-state devices or trapped ions. Neutral-atom systems can arrange many atoms in flexible patterns and control them with lasers, offering a potential path to scaling quantum processors while reducing some manufacturing challenges associated with chip-based qubits.
Ytterbium offers several practical advantages for neutral-atom quantum computing, including a rich energy-level structure, stable nuclear-spin qubit states and optical transitions that can support precise laser control, measurement and error detection. Compared with more commonly used alkali atoms such as rubidium or cesium, ytterbium’s simpler electron structure can reduce some sources of noise and crosstalk, which may help with scaling larger, more reliable neutral-atom processors.
The deal is attracting attention for a number of reasons beyond the Microsoft connection. Some experts and commentators are pointing out that the size of the raise is quite large compared to the relative newness of the startup — about six months old. The raise also attracted a number of major investors who are spread out across finance and industry, another sign of the increasing importance of quantum not just the raise for this particular startup, but, the broader Chinese quantum industry.
