晶体结构的量子叠加

Quantum superpositions of crystalline structures

Jens D. Baltrusch, Cecilia Cormick, Gabriele De Chiara, Tommaso Calarco, Giovanna Morigi

摘要:

讨论了离子弦运动态相干叠加的产生过程。运动态跨越结构转变线性-Z字形,并且它们的相干叠加通过自旋依赖力实现,使得一个离子的电子态的相干叠加演变成链的内部和外部自由度之间的纠缠态。结果表明,这种纠缠态的产生可以通过对链中的一个离子进行拉姆齐干涉来揭示。

英文摘要:

A procedure is discussed for creating coherent superpositions of motional states of ion strings. The motional states are across the structural transition linear-zigzag, and their coherent superposition is achieved by means of spin-dependent forces, such that a coherent superposition of the electronic states of one ion evolves into an entangled state between the chain's internal and external degrees of freedom. It is shown that the creation of such an entangled state can be revealed by performing Ramsey interferometry with one ion of the chain.
