Practical realization of quantum devices calls for the placement of individual qubits on complex nanophotonic circuits. However, this prerequisite continues to suffer from coarse positioning accuracy, low throughput, and process complexity. We developed a novel nanoprinting scheme that allows the controllable placement of nitrogen-vacancy (NV) center nanodiamonds at the quantum level. The scheme enables remarkable achievements that are not attainable by other approaches: (1) single-quantum level quantity control, (2) sub-wavelength positional accuracy, and (3) scalable, ‘lithography-free’ patterning capability. We believe this work to be a game-changer, as it directly addresses the key technological challenge associated with the realization of quantum devices. The patent for this invention has been filed (US 63/236,411, PCT Application No. PCT/CN2022/113516).
Second Exhibition – Digitization
Exhibition started from 18th August 2022
Digitalization is the theme of the second exhibition. Thirteen cutting-edge engineering research projects led by Professors in the Faculty of Engineering are exhibited in the Tam Wing Fan Innovation Wing Two and online Metaverse. These projects address both local and global situations relevant to digitization. From the videos and displays, visitors will be equipped with knowledge of rationales underlying these projects and their methodologies to achieve the goal. Further through interactive prototypes and functional exhibits in Innovation Wing Two, visitors will get even more detailed knowledge about how these research ideas have been translated into reality.
