As existing electronic and optical devices get smaller, they approach the fundamental limits set by quantum mechanics and a new paradigm has to be adopted for future progress. A promising direction for future quantum devices is based on coherence in matter. In a thermal incoherent light source, such as a light bulb or a candle, photons are emitted randomly. But one can design a device that forces them to move coherently in a single state - a laser. Similar states can be achieved with matter particles. Bose Einstein condensation of cold atoms is a Nobel Prize winning achievement demonstrating such matter coherence. Our lab has shown several new phenomena using cold-atom condensates. However, laser cooling atoms presents significant technical and financial challenges.

随着现有的电子和光学设备变得越来越小，它们接近量子力学设定的基本极限，必须为未来的发展采用新的范式。未来量子器件的一个有希望的方向是基于物质的相干性。在热非相干光源中，例如灯泡或蜡烛，光子随机发射。但我们可以设计一种装置，迫使它们在单一状态下相干运动-激光。物质粒子也可以达到类似的状态。玻色爱因斯坦凝聚冷原子是一项获得诺贝尔奖的成就，证明了这种物质的相干性。我们的实验室利用冷原子凝聚体展示了几种新现象。然而，激光冷却原子提出了重大的技术和财政挑战。
