原子干涉测量法提供的高精度和可扩展技术有机会对重力测量产生深远影响，从而能够探测更小尺寸或更大深度的特征。虽然这样的系统已经开始进入商业市场，但为了达到传统设备的尺寸、重量和功率，需要显著减小。在这篇文章中，原子干涉重力测量的潜力进行了评估，这表明，关键的机会在于重力梯度传感器的发展，使测量时间大幅改善。为了推进实现更紧凑的系统，已经追求实现高度便携式磁光阱系统的技术，该系统代表原子干涉测量系统的核心包。这可以在20 l和10 kg的系统包内创建107个原子的云，消耗80 W的功率。本文是“21世纪的量子技术”主题的一部分。
The high precision and scalable technology offered by atom interferometry has the opportunity to profoundly affect gravity surveys, enabling the detection of features of either smaller size or greater depth. While such systems are already starting to enter into the commercial market, significant reductions are required in order to reach the size, weight and power of conventional devices. In this article, the potential for atom interferometry based gravimetry is assessed, suggesting that the key opportunity resides within the development of gravity gradiometry sensors to enable drastic improvements in measurement time. To push forward in realizing more compact systems, techniques have been pursued to realize a highly portable magneto-optical trap system, which represents the core package of an atom interferometry system. This can create clouds of 107 atoms within a system package of 20 l and 10 kg, consuming 80 W of power. This article is part of the themed issue ‘Quantum technology for the 21st century’.
