Recently, Logical Qubit Technology successively completed Pre-A+ and Pre-A++ rounds of financing totaling billions of yuan. The Pre-A++ round was jointly led by Dachen Caizhi and Jingwei Chuangtou, with follow-on investments from Huakong Fund, Shenchuangtou, Kangjun Capital, and existing shareholders Zhejiang University Lianchuang, Dongfang Jiafu, Huaxia Hengtian, Chengshun Zhao, Xihu Keji Chuangtou, among others, continuing to add investment. The Pre-A+ round investors include Haowang Capital under Pudong Keji Group, Lushi Investment, and existing shareholder Zhejiang Province Chuangtou Investment Group's Keji Muji Fund continuing to add investment. The two rounds of financing will mainly be used to accelerate the development of superconducting quantum computing chips and integrated systems, including improving chip micro-nano processing equipment, accelerating the construction of quantum computing control platforms, and deploying quantum computing cloud platforms, among others.
Chip Design, Manufacturing, and Engineering Capabilities Are the Moat
Superconducting quantum computing is based on semiconductor micro-nano processing technology and radio frequency microwave control technology, offering considerable advantages in scalability and control speed, making it a mainstream quantum computing platform internationally.
For general-purpose quantum computing, superconducting quantum computing still faces some technical and engineering challenges. The core lies in improving quantum chip performance while scaling up, thereby achieving fault-tolerant logical qubits and practical quantum advantage. Therefore, breakthroughs are needed in areas such as superconducting quantum chip design, micro-nano process flows, and quantum control methods, while simultaneously enhancing engineering capabilities. This includes higher integration quantum measurement and control systems, higher density radio frequency signal transmission systems, higher cooling capacity low-temperature systems, and more intelligent quantum control software, among others.
Logicbit Technology was incubated from the superconducting quantum computing team of Zhejiang University. Team leader Professor Wang Haohua studied under Professor John Martinis (who won the 2025 Nobel Prize in Physics for contributions to superconducting circuit quantum computing), has been deeply engaged in superconducting quantum computing technology for nearly two decades, and has three times set world records for the global entanglement fidelity of superconducting quantum systems. The team has successively released superconducting quantum chips such as "Tianmu" and "Mogan," with core technical indicators such as bit fidelity, coherence time, and two-qubit gate accuracy at world-leading levels. Since its establishment in June 2022, the company has acquired complete technology for superconducting quantum computers through intellectual property transformation and continuous technological development, including chip design and manufacturing, quantum measurement and control systems, radio frequency transmission, software control, quantum algorithm computing power, etc. Recently, the company has achieved the following results in the development, engineering, and commercialization of superconducting quantum chip technology:
At the superconducting quantum chip technology level:
In August 2025, core members of Logicbit Technology published their latest research results in the main journal Nature, realizing a new type of "hot" topological edge state on the independently developed "Tianmu 2" hundred-qubit quantum chip, providing a new path for protecting fragile quantum information.
In September 2025, Logicbit Technology was selected for the Ministry of Industry and Information Technology's "Unveiling and Leading" quantum error correction coding project.
In November 2025, based on outstanding achievements in superconducting quantum chip technology, Logicbit Technology was selected as one of Zhejiang Province's first batch of key cultivation enterprises for the "Four Reservoirs" of future industries.
In January 2026, core members of Logicbit Technology participated in completing the world's first experimental demonstration of qLDPC quantum error correction on the self-developed "Kunlun" high-connectivity superconducting quantum chip, exploring and practicing new error correction methods while continuously advancing surface code error correction technology.
In February 2026, the scientific and technological achievement "Key Technologies and Applications of High-Connectivity Architecture Superconducting Quantum Chips," jointly completed by Zhejiang University, Zhejiang University Hangzhou International Science and Technology Innovation Center, and Logicbit Technology, won the first prize of the Zhejiang Provincial Technology Invention Award.
At the engineering level:
The company independently developed a high-synchronization, high-precision, high-efficiency hundred-qubit measurement and control system, with a modular architecture scalable to synchronous control of thousands of qubits. Using a "classical computing + quantum sampling" hybrid computing approach, this system supports the rapid solution of combinatorial optimization problems on the Tianmu 2 superconducting quantum chip.
To minimize thermal load, noise, and crosstalk, and achieve efficient, high-fidelity signal transmission, the team self-developed a high-density flexible cable radio frequency system with good low-temperature compatibility, high-fidelity signal transmission, and multi-channel integration, capable of achieving >99.9% single-qubit gate fidelity, laying the foundation for the next step of achieving thousand-qubit measurement and control.
Furthermore, to accelerate the iteration speed of superconducting quantum chips, the team established a chip micro-nano processing center and a control center, building five quantum computer integrated systems. On this basis, significant technological achievements such as small-scale chips approaching millisecond-level coherence time were achieved.
"In recent years, superconducting quantum chips have made very significant improvements and have always been the team's most focused area and core capability. For general-purpose quantum computing, larger-scale integration is needed, which will still take several years. The long-term competition in quantum computing depends on technological leadership and engineering capabilities, which is what the team has been striving for," said Wang Zhen, founder and CEO of Logicbit Technology.
Commercialization Capability Validated
Over the past six months, while continuously advancing technological innovation, Logicbit Technology has also achieved fruitful results in commercialization: successfully winning and delivering a project worth tens of millions of RMB for a large scientific research institute and university client, with the superconducting quantum chip being the sole-source procurement; winning a project for a small-scale quantum computer from a certain university. Completed a small-scale commercialization closed loop in the scientific research field.
Accompanied by the sharp increase in demand for computing power and the rising popularity of quantum computing, more and more commercial companies are beginning to turn their attention to quantum computing, and the commercialization process is gradually transitioning from "scientific computing" to the "industrial promotion" stage. In this process, Logicbit Technology has also begun to cooperate with leading domestic companies in pharmaceuticals, materials, finance, and other fields, gaining an in-depth understanding of specific business scenarios and gradually exploring quantum computing applications.
"Engaging in the technological development and industrial promotion of quantum computing is a very challenging endeavor," said Wang Zhen. "The popularity of quantum computing is very high now, but we are soberly aware that this is a long-term undertaking. We hope to do a good job in technology while exploring the path of quantum computing commercialization with products such as quantum computer integrated systems and cloud platforms, doing things that accumulate over the long term, and letting everyone personally feel the tremendous changes that quantum computing brings to society."
