On February 9th, at the province-wide conference on building a first-class innovation ecosystem and creating the most competitive business environment, the scientific and technological achievement titled "Key Technologies and Applications of High-Connectivity Architecture Superconducting Quantum Chips," jointly completed by Zhejiang University, Zhejiang University Hangzhou International Science and Innovation Center, and Hangzhou Logicbit Technology Co., Ltd., was honored with the Zhejiang Province First Prize for Technological Invention Award.
Addressing the major strategic needs of national quantum technology, the project pioneered the proposal of a multi-qubit superconducting quantum chip high-connectivity architecture, invented high-precision control technologies, and realized core supporting equipment and monitoring systems for multi-qubit chips. It has been applied and promoted in areas such as quantum physics simulation, optimization problem solving, and cutting-edge equipment development, exploring a new path from independent research and development to industrial application of superconducting quantum chips, and achieving a series of internationally leading scientific and technological results.
Design and Fabrication of High-Connectivity Architecture Superconducting Quantum Chips
Based on the structure of superconducting resonant cavities coupled with long arms, the quantum bit connectivity capability within a limited chip area is significantly enhanced, forming a complete technological pathway covering chip design, fabrication, and packaging. This provides a key and feasible technical support for the large-scale expansion of superconducting quantum chips.
High-Connectivity Quantum Chip Control Technology
The results of quantum computation depend on the level of control over quantum bits. The project invented a high-precision two-qubit gate waveform control scheme that achieves noise resistance, significantly improving the noise immunity and control precision of two-qubit gates. Simultaneously, a high-fidelity quantum bit readout technology was established, enabling dynamic optimization of system performance during the operation, readout, and reset processes of quantum bits, providing strong technical support for manufacturing high-performance superconducting quantum chips and implementing quantum error correction.
Core Technologies of Multi-Qubit Quantum Monitoring System
The project innovatively invented a modularized hundred-qubit ultra-low noise quantum control system, capable of achieving 99.9% single-qubit gate fidelity and 99.5% two-qubit gate fidelity, effectively supporting the engineering and practical development of superconducting quantum computing systems.
