TAIYI Quantum raises 1 billion yuan for neutral-atom quantum computing

Shanghai-based quantum computing startup TAIYI Quantum announced on Oct. 14 that its cumulative financing has crossed 1 billion yuan (approximately $140 million) following a new investment round. The announcement comes less than a year after the business was established in January 2026.

The financing round included participation from venture capital firms, institutional funds, and strategic investors, according to a press release reported by The Quantum Insider. TAIYI Quantum develops hardware, control systems, and software platforms for ytterbium neutral-atom quantum computers.

The company said the capital will support engineering development, fault-tolerant system integration, real-time control architectures, and quantum error correction hardware integration. Ytterbium provides long-lived electronic states, flexible qubit encoding options, and features that support erasure-aware quantum error correction.

Rather than treating error correction as a later addition, TAIYI Quantum plans to incorporate fault-tolerance requirements directly into the initial design of its hardware, control systems, and software stack.

"Quantum computing is fundamentally a long-term systems engineering challenge," said Zhenghao Fang, co-founder and chief executive officer of TAIYI Quantum. "Our priority is to translate investment into engineering capabilities, bring together exceptional talent, and build the technological foundations for practical quantum computing."

The startup reported completing three key engineering milestones since its launch. Within six months of founding, TAIYI Quantum integrated its first-generation prototype, combining laser and optical subsystems, atomic manipulation, vacuum systems, measurement electronics, real-time control, and software into a single experimental platform.

It also created an initial closed-loop control system with hardware-accelerated processing that achieves feedback latency in the tens of microseconds. The architecture is designed to support complex operations such as atom rearrangement and future error correction protocols.

In addition, TAIYI Quantum released LUOSHU, an open-source quantum compiler built for neutral-atom hardware. The tool emphasizes hardware-aware compilation and software-hardware co-design.

"Scaling physical qubit numbers alone will not deliver practical quantum computing," said Dr. Hongbin Liu, co-founder and chief technology officer of TAIYI Quantum. "The challenge is to build an architecture in which physical qubits, quantum error correction, real-time control, and logical operations work together as an integrated computational system."
