Quantum Dynamics of Ultra-Cold Atoms

这项提议旨在继续一项关于超冷原子量子输运的研究计划。PI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凝聚体的量子输运，重点是真实空间中的输运。此外，还将进行实验，以非常高的保真度从玻色-爱因斯坦凝聚体中提取单原子，原子保持在势垒(量子镊子)的基态。最后，该项目将实现与原子的多粒子干涉测量。就这项研究的更广泛影响而言，在特定量子状态下制备单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.
