在理解和控制量子技术方面的最新进展，例如基于冷原子的技术，已经导致了具有非凡计量性能的设备。为了在实验室环境之外实现这一潜力，需要降低尺寸、重量和功耗。在这里，我们演示了激光粉床融合的使用，这是一种附加制造技术，作为与制造量子传感器相关的生产技术。作为演示，我们使用添加制造技术构建了两个关键组件，即磁屏蔽室和真空室。最初的磁屏蔽原型显示，屏蔽系数在传统方法的3倍以内。真空演示装置表明，3D打印的钛结构适合用作真空室，测试系统的基本压力为5 ± 0.5mbar× 10−10mbar。这些演示展示了将添加剂制造用于基于冷原子的量子技术的相当大的前景，在未来实现更好的集成结构，从而降低尺寸、重量和组装复杂性。
Recent advances in the understanding and control of quantum technologies, such as those based on cold atoms, have resulted in devices with extraordinary metrological performance. To realise this potential outside of a lab environment the size, weight and power consumption need to be reduced. Here we demonstrate the use of laser powder bed fusion, an additive manufacturing technique, as a production technique relevant to the manufacture of quantum sensors. As a demonstration we have constructed two key components using additive manufacturing, namely magnetic shielding and vacuum chambers. The initial prototypes for magnetic shields show shielding factors within a factor of 3 of conventional approaches. The vacuum demonstrator device shows that 3D-printed titanium structures are suitable for use as vacuum chambers, with the test system reaching base pressures of 5 ± 0.5 × 10−10 mbar. These demonstrations show considerable promise for the use of additive manufacturing for cold atom based quantum technologies, in future enabling improved integrated structures, allowing for the reduction in size, weight and assembly complexity.
