原子气体的制备、控制和测量的最新进展使人们对量子世界有了新的认识，并产生了前所未有的灵敏度，例如在测量引力和磁场方面。将这些能力应用于生物医学成像、非侵入式地下测绘和无GPS导航等不同领域的全部潜力只能通过可规模生产高效、坚固和便携式设备来实现。我们引入增材制造作为量子器件组件的生产技术，具有无与伦比的设计自由度和快速原型制作。这提供了效率、紧凑性的阶跃变化，并促进了系统集成。作为一个演示，我们提出了一个与真空兼容的超冷原子源，在场产生过程中消耗不到10毫瓦的电功率，以产生大的冷铷气体样品。这种颠覆性的技术为大幅改进集成结构打开了大门，这将进一步降低定制便携式量子设备可扩展系列制造的尺寸和组装复杂性。
Recent advances in the preparation, control and measurement of atomic gases have led to new insights into the quantum world and unprecedented metrological sensitivities, e.g. in measuring gravitational forces and magnetic fields. The full potential of applying such capabilities to areas as diverse as biomedical imaging, non-invasive underground mapping, and GPS-free navigation can only be realised with the scalable production of efficient, robust and portable devices. We introduce additive manufacturing as a production technique of quantum device components with unrivalled design freedom and rapid prototyping. This provides a step change in efficiency, compactness and facilitates systems integration. As a demonstrator we present an ultrahigh vacuum compatible ultracold atom source dissipating less than ten milliwatts of electrical power during field generation to produce large samples of cold rubidium gases. This disruptive technology opens the door to drastically improved integrated structures, which will further reduce size and assembly complexity in scalable series manufacture of bespoke portable quantum devices.
