Quantum Dynamics of Ultra-Cold Atoms

本提案旨在继续研究超冷原子的量子输运。该项目将研究光学台球中超冷原子的量子结构和动力学，并测量二维光学晶格中超冷原子和冷凝物的量子输运，重点研究现实空间中的输运。此外，实验将以非常高的保真度从玻色-爱因斯坦凝聚体中提取单个原子，原子保持在势阱（量子镊子）的基态。最后，本计画将实现原子的多粒子干涉测量。在更广泛的研究影响上，在特定量子态下制备单个原子是几种不同的量子计算和量子信息处理方案的基础。

This proposal aims to continue a research program on quantum transport of ultra-cold atoms. The PI will investigate quantum structure and dynamics of ultra-cold atoms in optical billiards and to measure quantum transport of ultra-cold atoms and condensates in two-dimensional optical lattices, with the focus on the transport in real space. In addition, experiments will be performed on the extraction of single atoms from a Bose-Einstein condensate with very high fidelity, with the atoms remaining in the ground state of a potential well (a quantum tweezer). Finally the project will implement multi-particle interferometry with atoms. On the broader impact of the research, the preparation of single atoms in a specified quantum state is the basis for several different schemes for quantum computation and quantum information processing.
