Microfabricated devices for confining atomic particles are set to feature as essential core components in a range of quantum-enabled instrumentation during the coming years. Applications of these devices are in instruments such as atomic clocks and sensors, for use in precision positioning, navigation and timing. Additionally, these chip-scale devices will also be used in quantum information science and technology, for example as a processor or a node in a quantum network. Overall, applications range from laboratory research in fundamental science to practical quantum instruments. The UK's National Physical Laboratory has developed novel chip-scale ion traps and atom traps, which are made using advanced microfabrication techniques. A second generation of superior devices with added functionality is being tested now. The purpose of these devices is to trap strings of ions for ion-ion quantum entanglement. These will be used, together with a range of techniques in the coherent control of trapped ions, to research entangled systems and their application to quantum metrology. This project aims to validate this platform for new technology developments using quantum physics as a core component.

用于限制原子粒子的微型制造设备将在未来几年成为一系列量子仪器的关键核心部件。这些设备的应用是在原子钟和传感器等仪器中，用于精确定位、导航和计时。此外，这些芯片级设备还将用于量子信息科学和技术，例如作为量子网络中的处理器或节点。总体而言，应用范围从基础科学的实验室研究到实用的量子仪器。英国国家物理实验室开发了新型芯片规模的离子陷阱和原子陷阱，这些陷阱是使用先进的微制造技术制造的。具有附加功能的第二代高级设备现在正在测试中。这些装置的目的是捕获离子串，以实现离子与离子的量子纠缠。这些技术将与囚禁离子相干控制的一系列技术一起用于研究纠缠系统及其在量子计量中的应用。该项目旨在使用量子物理作为核心组件来验证该平台是否适用于新技术开发。
