Breakthrough in Atom-Based Quantum Computing: Pan Jianwei's Team Announces Scalable Neutral Atom Quantum Processor
In an exciting development, Pan Jianwei's team at the University of Science and Technology of China has made a significant stride in the field of atom-based quantum computing. The team has created a highly scalable neutral atom quantum processor, marking a major step towards large-scale, stable atomic quantum computers.
The advancement involves a real-time AI-controlled system with a spatial light modulator that can simultaneously position thousands of atoms using optical tweezers in just 60 milliseconds. Remarkably, the arrangement time remains constant, regardless of the number of atoms, enabling the method to manage tens of thousands of qubits efficiently.
The team demonstrated this with arrays 10 times larger than previous systems, organized into precise 2D and 3D structures. They achieved world-class quantum operation fidelities—about 99.97% for single-qubit gates and 99.5% for two-qubit gates—which match top global standards.
This breakthrough addresses a major bottleneck in scaling neutral atom qubits, which are inherently stable and suitable for dense quantum architectures. It is seen as a significant step forward in experimental feasibility within atom-related quantum physics and supports ambitions for a global secure quantum communication network.
The team's advancement includes the use of a spatial light modulator and an AI system for precise, fast, and scalable atom placement. More than 2,000 rubidium atoms were arranged into perfect patterns, with each atom serving as a qubit, the basic unit of quantum computing.
This latest advancement in atom-based quantum computing comes at a time when quantum computing is experiencing rapid advances across various platforms. The achievement sets a new standard in neutral atom quantum computing scalability and control, pushing the field closer to large-scale fault-tolerant quantum machines.
