Abstract

Out of a single Bose-Einstein condensate (BEC), we create two simultaneous interferometers, as employed for the differentiation between rotations and accelerations. Our method exploits the precise motion control of BECs combined with the precise momentum transfer by double Bragg diffraction for interferometry. In this way, the scheme avoids the complexity of two BEC sources and can be readily extended to a six-axis quantum inertial measurement unit.

使用Bose-Einstein冷凝液进行差分干涉测量

摘要

在单一的玻色-爱因斯坦冷凝物（BEC）中，我们创建了两个同时干涉仪，用于区分旋转和加速度。我们的方法利用了BEC的精确运动控制，并结合了通过双Bragg衍射进行干涉的精确动量传递。这样，该方案避免了两个BEC源的复杂性，并且可以很容易地扩展到六轴量子惯性测量单元。
