Yunqi Capital Joins Taiyi Liangsheng's 300 Million Yuan Pre-A Round, Neutral-Atom Quantum Computing Enters Acceleration Phase | Yunqi Partners

As demand for computing power keeps climbing, quantum computing is emerging as a critical frontier in next-generation computing architectures.

Recently, neutral-atom quantum computing company "Taiyi Liangsheng" announced the completion of a 300 million yuan Pre-A funding round, with participation from the Yunqi–Shanghai Jiao Tong University AI Angel Fund. As the first domestic company focused on complete ytterbium neutral-atom quantum computers, Taiyi Liangsheng has assembled its core R&D and commercial operations teams within its first hundred days and has already made progress across multiple key milestones. In this edition of Yunqi Partners, we bring you the details.

Recently, neutral-atom quantum computing company Taiyi Liangsheng (Shanghai) Quantum Technology Co., Ltd. ("Taiyi Liangsheng") completed a 300 million yuan Pre-A funding round, led by Gaorong Ventures and IDG Capital, with several well-known institutions and strategic investors — including Yunqi — participating as co-investors.

Founded in January 2026 and headquartered in Shanghai's Xuhui District, Taiyi Liangsheng is the first domestic company dedicated to complete ytterbium neutral-atom quantum computers. The ytterbium-atom approach offers several intrinsic physical advantages: erasure-type error correction, faster qubit gates, native high-fidelity multi-qubit gates, and multi-photon interconnectivity through telecom-band wavelengths. In March 2026, Google Quantum AI formally elevated neutral atoms to a core research priority; its neutral-atom hardware team, led by Adam Kaufman, also adopted the ytterbium-atom approach. Google explicitly stated that superconducting qubits scale more easily in the "time dimension," while neutral atoms scale more easily in the "spatial dimension."

Since its angel round, the company has rapidly built out its core R&D and commercial operations teams. It now has nearly 50 full-time employees covering the full technical stack, including cold atoms, optics, control systems, and quantum error correction. Core team members hail from MIT, JILA (Joint Institute for Laboratory Astrophysics), NIST (National Institute of Standards and Technology), CQT (Centre for Quantum Technologies Singapore), Microsoft, and other leading international research institutions, as well as top domestic universities and institutes, bringing together multidisciplinary expertise spanning quantum computing, atomic/molecular/optical physics, optical engineering, cryogenics and vacuum systems, control systems, algorithms, and software. Leadership is already in place across multiple core functions.

On the technical front, the company has established joint laboratories and collaborative research projects with leading quantum computing and quantum precision measurement groups at Peking University, Fudan University, and East China Normal University. Its full-time R&D team has completed the build-out of two optical tweezer systems and, in collaboration with Peking University, designed a vacuum chamber capable of continuous atom loading. By year-end, the company expects to complete its first complete quantum computer and demonstrate logical qubits through quantum error correction.

Taiyi Liangsheng is targeting future applications in AI training and scientific computing, chemical simulation, materials R&D, drug discovery, financial modeling, and information security. The company is already working with leading industry players in materials, chemicals, pharmaceuticals, and finance to validate quantum algorithms on real-world problems and explore the potential value of quantum computing in specific industrial applications.

Yunqi Capital's Perspective

At a moment when multiple quantum computing approaches are advancing in parallel, the neutral-atom route is drawing sustained attention from the global research and business communities for its potential in spatial scaling, qubit manipulation, and quantum error correction. We are optimistic about Taiyi Liangsheng's technical foundation, engineering execution, and industrialization efforts in the ytterbium neutral-atom direction, and look forward to seeing the company continue pushing practical quantum computing forward.
