A research team from the Computer Communications Laboratory (CCL) [1] has won the Best Paper Award at the 2025 International Conference on Advanced Technologies for Communications (ATC'2025), held in Hanoi, Vietnam.
The International Conference on Advanced Technologies for Communications is an annual event co-organized by the Radio & Electronics Association of Vietnam (REV) and the IEEE Communications Society (IEEE ComSoc) [2]. Since its launch in 2008, ATC has served as a leading international forum for scientists and engineers to exchange ideas and share research in electronics, communications, and related fields. This year's conference took place from October 16-18, 2025, hosted by Hanoi University of Industry, and featured keynote talks from distinguished experts along with presentations from top researchers around the world.
The award-winning paper, titled "Qiskit-Enabled Simulation of Quantum Key Distribution over Starlink Satellite Networks", was authored by Takihara Yudai, Prof. Hoang Le, Cuong Nguyen (Ph.D. student at CCL), and Prof. Anh T. Pham.
Mr. Takihara attended the conference and accepted the award on behalf of the research team.
The paper introduces a novel simulation framework using the IBM Quantum Experience (IQX) platform to emulate real-world Quantum Key Distribution (QKD) protocols in the emerging context of the Internet from Space. By simulating and evaluating key performance indicators - including secret key rate and quantum bit error rate - the research offers valuable insights into the feasibility and challenges of implementing QKD systems over free-space optical satellite links.
This work was supported by Kakenhi projects #21K11870 [3] and #24K14918. Mr. Takihara is currently pursuing a master's degree through the UoA 5-year BS/MS (4+1) program at CCL, under the supervision of Prof. Anh T. Pham and Assoc. Prof. Hoang Le. His research focuses on the design and performance evaluation of QKD systems over free-space optical satellite networks.
