标题： Quantum state manipulation of trapped atomic ions

摘要： 使用一个激光冷却并捕获的9Be+离子来研究相干量子态合成和量子逻辑的方法。 我们创建并表征了运动的非经典状态，包括“薛定谔猫”状态。 实现了一个基本的量子逻辑门，该门使用量子化离子运动的两个状态和离子内部的两个状态作为量子比特。 我们探讨了基于多个捕获离子实现量子计算的一些应用及问题。 显示英文摘要

摘要： A single laser-cooled and trapped 9Be+ ion is used to investigate methods of coherent quantum-state synthesis and quantum logic. We create and characterize nonclassical states of motion including "Schroedinger-cat" states. A fundamental quantum logic gate is realized which uses two states of the quantized ion motion and two ion internal states as qubits. We explore some of the applications for, and problems in realizing, quantum computation based on multiple trapped ions.
