摘要
Building a physical system for quantum computation requires the scalable preparation of coherent two-level systems that can serve as qubits, together with single-qubit-resolved control and detection capabilities. Cold atoms, as natural quantum systems, possess excellent coherence properties and scalability. In recent years, the rapid development of quantum gas microscopes and optical tweezer array techniques has enabled single-atom–resolved manipulation and detection while maintaining large-scale scalability. These advances have brought cold atoms to the forefront as one of the most promising platforms for next-generation quantum computation.
Another key aspect of quantum computation lies in the suppression and elimination of errors or defects. The progress in non-destructive detection and defect correction in cold-atom systems has further enhanced their potential for realizing fault-tolerant quantum computation.
In this talk, I will introduce the key physical principles, recent advances, and future prospects of quantum computing research based on trapped cold atoms, focusing on our Yb-171 atom array experimental platform in BAQIS (Beijing Academy of Quantum Information Sciences). The discussion will include enhanced atom loading, cooling, high-fidelity detection, coherent qubit control, and defect correction techniques—toward the realization of a scalable and robust quantum computing system.
