点击翻译按钮获取中文摘要

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.
