ITR: Quantum Information Processing with Ultracold Rydberg Atoms

EIA-0082913 Cote，RobinUniversity of ConnecticutITR：量子信息处理与超冷里德伯原子超冷里德伯原子具有很长的寿命和强烈的相互作用，在很大的距离，这可能使他们成为理想的量子信息处理。 该项目正在通过研究和实验实现一个通用的双量子位逻辑门来研究这种可能性，在这个逻辑门中，两个原子的状态获得了一个取决于原子相互作用时间的相位。 该项目正在研究含有里德伯原子的稀疏光学晶格，这将允许制备任意状态的可识别原子。 本课程将探讨原子间相互作用的性质，包括外加电场与磁场的影响。 最后，将研究阅读存储在里德堡原子中的信息的方法，包括成像荧光和选择性电离。 将探索大量量子比特的缩放，以及光学晶格对退相干的影响。

EIA-0082913Cote, RobinUniversity of ConnecticutITR: Quantum Information Processing with Ultracold Rydberg AtomsUltracold Rydberg atoms have long lifetimes and interact strongly at large distances, which may make them ideal for quantum information processing. This project is investigating this possibility by studying and experimentally implementing a universal two-qubit logic gate, in which a two-atom state acquires a phase that depends on the time the atoms are interacting. The project is investigating sparsely populated optical lattices containing Rydberg atoms, which will permit the preparation of well-identified atoms in arbitrary states. The properties of atom-atom interactions, including the effect of external electric and magnetic fields will be investigated. Finally, methods of reading the information stored in Rydberg atoms will be investigated, including imaged fluorescence and selective ionization. Scaling to large numbers of qubits, as well as the effects of the optical lattice on decoherence, will be explored.
