The establishment of the Jiangsu Provincial Key Laboratory of Quantum Information Science and Technology is built upon a solid research foundation in the field of quantum information. In the area of superconducting quantum computing, the laboratory's research team is dedicated to improving the precision of quantum gate manipulation, achieving two-qubit gate fidelity at internationally leading levels and realizing the first experimental measurement of the quantum metric. In quantum communication, the team accomplished the first active optical quantum chip with electro-optic modulation and the first experimental realization of a nonlocal quantum delayed-choice experiment. In quantum precision measurement, the team developed artificial intelligence-enhanced precision magnetometry technology and measurement techniques surpassing the standard quantum limit. In fundamental quantum theory, the team established a topological material classification database and detected gravitons. In quantum benchmark engineering, to overcome the bottleneck of ultra-low-temperature thermometry in cutting-edge fields such as quantum computing, the laboratory successfully developed and engineered a 100mK ultra-low-temperature sensing device based on superconducting quantum interference devices (SQUIDs). The project achieved breakthroughs in SQUID sensor integration, addressed key technical challenges such as signal integrity transmission in cryogenic environments and the suppression and verification of environmental background noise, and established a complete ultra-low-temperature noise thermometry system. Currently, this device achieves precise measurements within the temperature range of 100mK to 1K, with thermodynamic temperature measurement uncertainty better than 5% in this range, reaching domestically advanced levels. The relevant parameters have passed the acceptance review of the quality enhancement chain project. This achievement provides reliable technical support for the performance evaluation of China's core quantum devices and the independent development of cryogenic equipment.

        Since its establishment, the laboratory has published 10 high-quality academic papers, four of which appeared in top-tier international journals such as Physical Review Letters (PRL) and Science China-Physics, Mechanics & Astronomy. The laboratory has filed 15 invention patent applications and has been granted 22 patents. It is currently undertaking 10 national-level projects and 7 provincial-level projects. The laboratory's research project, Quantum Phenomena and Their Applications in Superconducting Devices, received the second prize of the Natural Science Award of Jiangsu Province in 2024. Another key research achievement, Research and Application of Key Technologies for Quantum-Classical Fusion Platforms, successfully tackled core technical challenges such as the integration, adaptation, and efficient collaboration between quantum and classical computing systems, and was awarded the second prize of the Science and Technology Achievement Award by the Jiangsu Provincial Association of Engineers in 2025.
