Initial experiments concerning quantum information processing in rare-earth-ion doped crystals

M. Nilsson, L. Levin, N. Ohlsson, T. Christiansson, S. Kroll

摘要:

本文介绍了在固态材料中构造简单量子门的初步实验。其目的不是使用特别定制的材料,而是选择材料中随机分布的离子的子集,这些离子具有相互控制所需的相互作用,因此可以用于进行量子逻辑运算。实验结果表明,非均匀加宽的吸收线的一部分可以被选择作为量子比特,并且材料中的离子子集可以控制其他离子的共振频率。这为在稀土离子掺杂晶体中构建量子门开辟了道路。

英文摘要:

In this paper initial experiments towards constructing simple quantum gates in a solid state material are presented. Instead of using specially tailored materials, the aim is to select a subset of randomly distributed ions in the material, which have the interaction necessary to control each other and therefore can be used to do quantum logic operations. The experimental results demonstrate that part of an inhomogeneously broadened absorption line can be selected as a qubit and that a subset of ions in the material can control the resonance frequency of other ions. This opens the way for the construction of quantum gates in rare-earth-ion doped crystals.
