Study of Atomic Spin Entanglement in Optical Lattices

多粒子量子纠缠是进行量子计算的关键资源,近年来发展起来的光学晶格技术为操控大量超冷原子量子比特进行信息处理带来了机遇.介绍在超冷原子自旋比特纠缠实验研究中取得的最新进展.此工作为使用光晶格中超冷原子间纠缠进行量子计算奠定了实验基础.

Multipartite entanglement is the key resource for quantum computation. Ultracold atoms in optical lattices provide a clean and tunable platform for generating scalable entangled states. We report the experimental progress on the creation and detection of atomic spin entanglement. Our experiment represents a fundamental step towards quantum computation with ultracold atoms in optical lattices.
