Core Viewpoint - The article highlights a significant breakthrough in quantum computing, where a team led by Pan Jianwei successfully constructed a defect-free atomic array of 2024 atoms in just 60 milliseconds, setting a new world record in neutral atom systems [1][6][14]. Group 1: Research Achievements - The research team utilized AI technology to achieve a high degree of parallelism in rearranging atoms, overcoming previous limitations in traditional methods that restricted the scale of atomic arrays to hundreds of atoms [12][14]. - The system has achieved single-qubit gate fidelity of 99.97%, two-qubit gate fidelity of 99.5%, and detection fidelity of 99.92%, matching the highest international standards represented by Harvard University [6][14]. - The results of this research have been published in the international journal "Physical Review Letters" and highlighted by the American Physical Society [4]. Group 2: Technical Innovations - The new rearrangement technique allows for the rapid reconfiguration of thousands of atoms, demonstrated through a video featuring Schrödinger's cat, showcasing the dynamic arrangement of rubidium atoms in a 230×230μm optical trap array [2][8]. - The research indicates that expanding the atomic array from 2024 to tens of thousands is feasible from a computational perspective, although practical implementation requires advancements in laser power and overall platform capabilities [14]. Group 3: Future Prospects - The article suggests that while the current advancements are significant, achieving a fully functional universal quantum computer may take an additional 10 years for large-scale applications like cryptography [14]. - The collaboration involves top teams in the quantum computing field, including the Shanghai Quantum Science Research Center and the University of Science and Technology of China [14].
