Coherent Control and Entanglement of Ions Confined in a Microfabricated Chip

在未来的几年里，用于限制原子粒子的微制造设备将成为一系列量子仪器中必不可少的核心部件。这些设备应用于原子钟和传感器等仪器中，用于精确定位、导航和定时。此外，这些芯片级设备还将用于量子信息科学与技术，例如作为处理器或量子网络中的节点。总的来说，应用范围从基础科学的实验室研究到实际的量子仪器。英国国家物理实验室开发了新型芯片级离子阱和原子阱，采用先进的微加工技术制造。现在正在测试具有附加功能的第二代高级设备。这些装置的目的是为了捕获离子串进行离子-离子量子纠缠。这些将与一系列捕获离子的相干控制技术一起用于研究纠缠系统及其在量子计量中的应用。该项目旨在以量子物理为核心组件验证该平台的新技术开发。

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.
