Demonstration of high-yield, high-performance ion microtraps

Grant funds

Chip-scale technology is necessary for atomic quantum devices of significantly reduced form factor. The National Physical Laboratory (NPL) has demonstrated a microchip device for the confinement of atomic ions. Its unique set of performance characteristics, together with the scalable fabrication techniques used to produce it, render it an excellent platform for an elementary component in atomic quantum technologies. Clocks, sensors and scalable superpositions and entanglement will benefit. NPL will conduct ion trapping performance tests on devices produced in an earlier IUK Study. Kelvin Nanotechnology will enhance the existing full-wafer scale microfabrication process to produce ion microtraps with ~90% target yield. Optocap will develop the principles for a custom electronic package, to enable ample connectivity for these and more complex devices in the future. To the best of our knowledge, this is the first attempt worldwide at this principle for ion microchip devices. This points the way towards the integration of these devices in atomic quantum instruments.

Novel frequency doubled laser platform for atomic quantum technologies

Grant funds

Miniaturised, portable chip-scale clocks and sensors are regarded as central priorities for future sensors, navigation and secure communication systems. The Royal Academy of Engineering has highlighted the vulnerability of global navigation satellite systems and recommends that all critical infrastructures relying on accurate time measurements should have a robust holdover alternative technology. This project addresses one of the key components in achieving this goal by implementing DFB laser and PPLN technology developed for consumer applications to produce a cost effective, miniature laser technology platform for achieving short wavelength sources for use in quantum systems and sensors. By utilising technology developed for picoprojector, head up display and near eye display applications we will achieve a step change in laser technologies for quantum applications resulting in a 10e5 reduction in form factor. The vision of this project is to demonstrate a scaleable, commercially viable technological approach to producing laser sources for quantum applications building on the partners experience in applying these techniques for consumer applications.
