**AI Breakthrough Enables Rapid Creation of Defect-Free Qubit Arrays, Advancing Quantum Computing**

**New Delhi, August 11, 2025** – A team of Chinese scientists has announced a groundbreaking advancement in the field of quantum computing, reporting the development of a novel method for creating large, defect-free arrays of neutral atoms, a crucial step towards building practical quantum computers. The research, published in *Physical Review Letters*, details how artificial intelligence (AI) is used to precisely manipulate and arrange thousands of atoms into ordered arrays at unprecedented speed.

Quantum computing, which promises to solve problems currently beyond the reach of classical computers, relies on qubits, or quantum bits. Neutral atoms, such as rubidium, can be used as qubits, trapped and controlled by focused laser beams called optical tweezers. Creating large, precisely positioned arrays of these atoms is essential for complex quantum operations and error correction. The main challenge has been avoiding defects.

Traditionally, assembling defect-free arrays involved moving atoms individually or row by row, a slow process that becomes increasingly cumbersome with larger arrays. The new method circumvents this limitation by employing an AI model to calculate the optimal way to move thousands of atoms simultaneously.

The AI, a convolutional neural network trained on simulated laser holograms, rapidly generates highly accurate holograms that guide the atoms in smooth movements with minimal loss. The system uses the Hungarian algorithm to find the ideal pairings between atoms and target positions, minimising the total distance atoms need to move while avoiding collisions. Each movement is split into approximately 20 small steps to prevent heating and atom loss. This process is so efficient that the rearrangement time remains roughly constant regardless of whether the array contains 1,000 or 10,000 atoms.

The team successfully assembled two-dimensional arrays of up to 2,024 atoms free of any defects in about 60 milliseconds, a substantial improvement over previous methods. They also created a cartoon video animating the Schrödinger’s cat thought experiment by choreographing 549 atoms in a 230 x 230 micrometre grid.

“This breakthrough has major implications for the future of scalable quantum computing,” said a representative from the research team. “The ability to quickly and reliably assemble large, defect-free atom arrays opens new avenues for building more powerful and complex quantum systems.”
