论文摘要
两离子晶体构成了一个调查量子性质的平台，可以将其扩展到任何离子物种或带电的颗粒，前提是晶体中的一个离子可以直接冷却并用激光辐射操纵。本文介绍了在7台开式式笔记陷阱中形成量子计量学的两离子晶体。 $^{40} $ ca $^+$ $离子是通过光电离世或在（Paul-trap）源内部产生的，通过超导螺线管的强磁场梯度运输，并以几个电子伏特的平均动能捕获了飞行器，以少数电动的数量触发了量的最小值。还介绍了强烈的磁场中两离子晶体以达到量子状态的激光冷却，并特别强调了径向模式的冷却。
Two-ion crystals constitute a platform for investigations of quantum nature that can be extended to any ion species or charged particle provided one of the ions in the crystal can be directly laser-cooled and manipulated with laser radiation. This paper presents the formation of two-ion crystals for quantum metrology in a 7-tesla open-ring Penning trap. $^{40}$Ca$^+$ ions are produced either internally by photoionization or externally in a (Paul-trap) source, transported through the strong magnetic field gradient of the superconducting solenoid, and captured in-flight with a mean kinetic energy of a few electronvolts with respect to the minimum of the Penning-trap potential well. Laser cooling of the two-ion crystal in a strong magnetic field towards reaching the quantum regime is also presented with particular emphasis on the cooling of the radial modes.
