论文摘要
实现更快的实验周期时间对于量子模拟的未来很重要。周期时间决定了可以采样多体波功能的频率，从而定义了从量子模拟中提取信息的速率。 We demonstrate a system which can produce a Bose-Einstein condensate of $8 \times 10^4$ $^{168}\text{Er}$ atoms with approximately 85% condensate fraction in 800 ms and a degenerate Fermi gas of $^{167}\text{Er}$ in 4 seconds, which are unprecedented times compared to many existing quantum gas experiments.这是通过几种新颖的冷却技术和一个可调偶极陷阱来完成的。此处用于加速量子退化气体产生的方法应适用于多种原子物种，并有望扩大量子模拟的能力。
Realizing faster experimental cycle times is important for the future of quantum simulation. The cycle time determines how often the many-body wave-function can be sampled, defining the rate at which information is extracted from the quantum simulation. We demonstrate a system which can produce a Bose-Einstein condensate of $8 \times 10^4$ $^{168}\text{Er}$ atoms with approximately 85% condensate fraction in 800 ms and a degenerate Fermi gas of $^{167}\text{Er}$ in 4 seconds, which are unprecedented times compared to many existing quantum gas experiments. This is accomplished by several novel cooling techniques and a tunable dipole trap. The methods used here for accelerating the production of quantum degenerate gases should be applicable to a variety of atomic species and are promising for expanding the capabilities of quantum simulation.
