A Bose Einstein condensate (BEC) is a collection of atoms, all in the same quantum state, like the photons in a laser. It is now possible to create a micro-BEC and move it around on an 'atom chip'. We propose an experimental and theoretical study of its properties including those quantum statistical effects which will limit future ultra-sensitive measurement technologies such as quantum electromechanical transducers. We will develop methods to count small numbers of ultra-cold atoms, engineer their state and build a prototype device.

玻色-爱因斯坦凝聚体（BEC）是原子的集合，它们都处于相同的量子态，就像激光中的光子一样。现在有可能制造出微型bec，并在“原子芯片”上移动它。我们建议对其特性进行实验和理论研究，包括量子统计效应，这将限制未来的超灵敏测量技术，如量子机电换能器。我们将开发方法来计算少量的超冷原子，设计它们的状态，并建立一个原型设备。
