项目摘要
This experimental quantum optics project continues work exploring the measurement and control of complex quantum mechanical systems with the ultimate goal of harnessing quantum mechanical systems as building blocks for practical tasks such as metrology, simulation, and information processing. The overriding goals of the research program are to perform experiments in which two basic questions of quantum mechanics are addressed: measurement of a system and control of the state of a quantum system in a manner that is robust against noise and errors. The specific quantum-mechanical systems to be controlled are in the form of individual atoms and in the form of many-body states of large ensembles of atoms. The experiments will be carried out in laser-cooled atomic gases. The specific goals of the project are to (1) control the 16-dimensional ground manifold of the Cs atom and (2) control and measure the collective spin of an atomic ensemble. The control in the first experiment will be affected through an interaction Hamiltonian generated by microwave and magnetic fields and optical lattices. In the second experiment the Hamiltonian will include optical feedback, continuous measurement, and quantum erasure. The broader impact of this work lies first in its connection to quantum control in chemistry, atomic clocks, and quantum information science. The second broader impact of this project is the education of graduate students as well as interaction with a network of university, national laboratory, and industry scientists studying quantum information science.
这个实验性的量子光学项目继续探索复杂量子力学系统的测量和控制,最终目标是利用量子力学系统作为实际任务的构建块,如计量、模拟和信息处理。该研究计划的首要目标是进行实验,其中涉及量子力学的两个基本问题:测量系统和以一种对噪声和误差具有健壮性的方式控制量子系统的状态。要控制的具体量子力学系统是以单个原子的形式和以大原子集合的多体状态的形式存在的。这些实验将在激光冷却的原子气体中进行。该项目的具体目标是(1)控制Cs原子的16维基流形和(2)控制和测量原子系综的集体自旋。第一个实验中的控制将通过微波、磁场和光学晶格产生的相互作用哈密顿量来影响。在第二个实验中,哈密顿量将包括光反馈、连续测量和量子擦除。这项工作更广泛的影响首先在于它与化学、原子钟和量子信息科学中的量子控制有关。该项目的第二个更广泛的影响是研究生的教育以及与学习量子信息科学的大学、国家实验室和工业科学家网络的互动。
