Abstract

Integrated photonics has grown in the last decade to fill the market with classical devices that offer tremendous SWaP benefits over conventional bulk optics and fiber components. For quantum systems the device losses were still too large to allow for large system scaling as well as too narrow a transparency window to cover all the qubit technologies. Over the last couple years, both industry and government laboratories have worked closely with commercial institutions to address both issues by reducing the waveguide losses and initiating the process to include ultrawide-bandgap photonic materials into the fabrication process. These research areas, the results, and the next steps forward for integrating other materials and qubit systems into the platform will be the subject of my talk.
