Development of Low-Loss, High-Finesse Nanofiber Optical Resonators for Distributed Quantum Computing

There is a significant global effort to develop fault-tolerant quantum computers, with a leading strategy being the creation of modular, distributed quantum networks. This approach requires high-fidelity “quantum interconnects” to link individual quantum processors. This project proposes to fabricate and optimize the fundamental component for these interconnects: ultra-low-loss, high-finesse nanofiber optical resonators. This will be achieved by using the specialized heat-and-pull fabrication process pioneered at Waseda University. These high-quality resonators are essential hardware for future scalable quantum computers and networks. Both Concordia University and Waseda University will benefit from the project. Concordia will gain direct access to Waseda’s world-class facilities and the critical know-how of this fabrication technique, which is currently unavailable at the home institution. Waseda University will benefit from the intern’s direct contributions to their ongoing research in nanofiber optimization, which is part of a national-level JST Moonshot program. This project will establish a new, foundational collaboration, paving the way for future joint publications and international projects.
