This experimental research program focuses on the study and control of the quantum statistics of atoms. The foundation for the proposed work is a unique system that has been developed primarily for this purpose. The starting point is a standard Bose-Einstein condensation (BEC) apparatus in rubidium, and a parallel system in sodium. Condensed atoms are transferred to a novel optical "box trap" which provides tight confinement in two dimensions and the capability of arbitrary potentials along the third (axial) dimension. The rubidium system will be devoted to quantum control, with the creation of single-atom Fock states. The sodium experiment will be devoted to the first statistical study of quantum critical phenomena, which should be able to explore the phase diagrams and phase transitions for a degenerate Bose gas. The broader impact of the program involves education, efforts at diversity and applications to quantum computing.

这个实验研究计划的重点是研究和控制原子的量子统计。拟议工作的基础是主要为此目的开发的独特系统。起始点是铷中的标准玻色-爱因斯坦凝聚（BEC）装置，以及钠中的平行系统。将凝聚态原子转移到一种新型的光学“盒阱”中，该阱在二维上提供了严格的限制，并在第三维（轴向）上提供了沿着任意势的能力。铷系统将致力于量子控制，创造单原子福克态。钠实验将致力于量子临界现象的第一次统计研究，这应该能够探索简并玻色气体的相图和相变。 该计划的更广泛影响涉及教育，多样性和量子计算应用的努力。
