Ultracold gases for quantum simulation

与社区中的人不同，当量子力学粒子处于有利条件下时，它们会找到共同行动、造福整体的方法。通过这些共同的行为，通常与微观粒子相关的量子效应变得可以在人类长度范围内获得和利用--允许实现与无损电子传输相关的超导效应和指数级更强大的“量子”计算。激光冷却的超冷量子气体实验为探索、操作、测量和访问这些现象提供了一个理想的试验场。有了这些工具，我们可以探索量子多体物理的起源，并设计出展示这种量子共同性的新表现的工程系统。

Not unlike people in communities, quantum mechanical particles find ways to act together, to benefit the whole, when placed under favourable conditions. Through these communal behaviours, quantum effects usually associated with microscopic particles become accessible and exploitable at human length scales -- permitting the realization of effects like superconductivity associated with lossless electrical transmission and exponentially more powerful "quantum" computation. Experiments with laser-cooled ultracold quantum gases provide an ideal testing ground for exploring, manipulating, measuring, and accessing these phenomena. With these tools, we can explore the origins of quantum many-body physics and engineer systems displaying new manifestations of this quantum communality.
