2026-02-09

On February 9, at the Zhejiang Province Conference on Building a World-Class Innovation Ecosystem and Creating the Most Competitive Business Environment, the scientific achievement Key Technologies and Applications of High-Connectivity Superconducting Quantum Chips, jointly completed by Zhejiang University, Zhejiang University Hangzhou Global Scientific and Technological Innovation Center, and Logical Qubit Technology, received the First Prize of the Zhejiang Provincial Technological Invention Award.

Addressing major national strategic demands in quantum technology, the research team pioneered a novel high-connectivity architecture for multi-qubit superconducting quantum chips, developed high-precision quantum control technologies, and realized core supporting equipment and measurement and control systems for multi-qubit chips. These achievements have been applied in areas including quantum simulation, combinatorial optimization, and advanced scientific instrumentation, establishing a new pathway from the independent development of superconducting quantum chips to industrial-scale applications while delivering a series of internationally leading scientific and technological breakthroughs.

High-Connectivity Superconducting Quantum Chip Architecture Design and Fabrication Technologies

By leveraging superconducting resonators and long-range coupler structures, the team significantly enhanced qubit connectivity within limited chip areas. This work established a complete technical framework covering chip design, fabrication, and packaging, providing critical and practical technological support for the large-scale scalability of superconducting quantum chips.

High-Connectivity Quantum Chip Control Technologies

Quantum computing performance fundamentally depends on the ability to precisely control qubits. The research team developed a high-precision, noise-resilient two-qubit gate waveform control scheme, significantly improving both the noise robustness and control accuracy of two-qubit gate operations.

At the same time, the team established a high-fidelity qubit readout technology that enables dynamic system optimization during qubit operation, readout, and reset processes. These advances provide strong technical support for the development of high-performance superconducting quantum chips and the realization of quantum error correction.

Core Technologies for Multi-Qubit Quantum Measurement and Control Systems

The team also developed an innovative modular 100-qubit ultra-low-noise quantum control system capable of achieving single-qubit gate fidelities of 99.9% and two-qubit gate fidelities of 99.5%. These technologies provide important engineering support for the scalable and practical development of superconducting quantum computing systems.
