论文摘要
最近，将thulium原子冷却至Bose-Einstein冷凝温度，从而用该原子打开了量子模拟的途径。但是，成功的模拟要求仪器控制原子的和读数状态，以及控制同一物种的不同物种或不同状态之间的相互作用的能力。在本文中，我们提供了对Thulium的基态磁性高空操纵高保真性（超过93％）的实验证明，该磁性使用微波炉（MW）天线的简单有效设计。还检查了基态高精细水平的相干时间和分离速率。
Recently, the thulium atom was cooled down to the Bose-Einstein condensation temperature, thus opening a pathway to quantum simulation with this atom. However, successful simulations require instruments to control and readout states of the atom as well as the ability to control the interaction between either different species or different states of the same type of species. In this paper, we provide an experimental demonstration of high-fidelity (over 93%) manipulation of the ground state magnetic sublevels of thulium, which utilizes a simple and efficient design of a microwave (MW) antenna. The coherence time and dephasing rate of the energetically highest hyperfine level of the ground state were also examined.
