QnTM: Manipulation of Quantum Entanglement & Decoherence in Neutral Atoms and Quantum Dots

量子计算[http://qist.lanl.gov]和量子信息科学的路线图得到了广泛的认可和广泛的关注，它揭示了中性原子和纳米系统中量子输运的空腔量子电动力学的重要性。这两个系统都非常重要，因为量子位定义得很好，并且可以产生很好的纠缠。此外，这些领域的技术进步使实验工作与理论工作同步。最近成功地将原子捕获在一个高质量的腔中，使这些原子保持更长时间，这对量子信息科学来说是一个重要的里程碑，这促进了对腔QED的研究。进一步提高了腔体的质量，这对于更好地控制退相干是至关重要的。更广泛的影响除了本提案的重要研究目标之外，更广泛的教育目标是为博士后、研究生和本科生提供机会。此外，首席研究员还将对当地高中生进行量子信息讲座。

Intellectual MeritThe much appreciated and extensively followed roadmap for quantum computing [http://qist.lanl.gov ]and quantum information science brings out the importance of cavity quantum electrodynamics withneutral atoms and quantum transport in nano-systems.Both the systems are extremely important as the qubits are very well defined and well characterized entanglement can be created.Besides the technological advances in these areas are making the experimental work catch fast with theory.The proposed work on cavity QED is facilitated by the very recent success on trapping atomsin a high quality cavity to hold these atoms for much longer times an important milestonefor the purposes of quantum information science.Further the quality of the cavity has beenimproved which is crucial for better control of decoherence.Broader ImpactBeyond the important research goals of this proposal,the broader educational goals areto provide opportunities for postdoc,graduate and undergraduate students.In addition,lectures on quantum information will be given by the principal investigators to local highschool students.
