They successfully constructed a defect-free two-dimensional and three-dimensional atomic array of up to 2024 atoms within 60 milliseconds, setting a new world record for the scale of defect-free atomic arrays in neutral atom systems. This method lays a key technical foundation for large-scale neutral atom quantum computing. The related research results were published on August 9 in the international academic journal \"Physical Review Letters\" in the form of \"Editor's Recommendation,\" and was specifically reported by the American Physical Society's \"Physics\" journal as a research highlight.\u003C\u002Fstrong>\u003C\u002Fp>\u003Cp>\u003Cbr>\u003C\u002Fp>\u003Cp>\u003Cspan style=\"font-size: 18px;\">Neutral atom systems have become a highly promising platform for quantum computing and quantum simulation due to their excellent scalability, high-fidelity quantum gates, high parallelism, and arbitrary connectivity. This system uses optical tweezers arrays to trap neutral atoms. First, it needs to convert the initial randomly filled atomic array into a defect-free atomic array through rearrangement technology, and then perform quantum logic gate operations. Traditional rearrangement methods are limited by time complexity increasing with the array scale, atomic loss, and computing speed, keeping the array scale at several hundred atoms, making further expansion difficult.\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cspan style=\"font-size: 18px;\">\t\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cspan style=\"font-size: 18px;\">To overcome this challenge, the research team innovatively developed artificial intelligence technology, which drives high-speed spatial light modulators in real-time for dynamic refresh. By precisely controlling the position and phase of the optical tweezers array, all atoms can be moved simultaneously. In this work, the research team demonstrated arbitrary configuration rearrangement of two-dimensional and three-dimensional atomic arrays, achieving a defect-free array of up to 2024 atoms, with a total time of only 60 milliseconds. As the atomic array scale increases, the time required for this rearrangement method remains constant, so it can be directly applied to the rearrangement of defect-free arrays of tens of thousands of atoms in the future.\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cspan style=\"font-size: 18px;\">\t\u003C\u002Fspan>\u003C\u002Fp>\u003Cp>\u003Cspan style=\"font-size: 18px;\">Currently, the system has a single-qubit gate fidelity of 99.97%, a two-qubit gate fidelity of 99.5%, and a detection fidelity of 99.92%, which has caught up with the international top level represented by Harvard University in the United States.
