As part of Moonshot Goal 6 (“Scalable and Robust Integrated Quantum Communication Systems”) led by Project Manager Shota Nagayama, we have released open-source device drivers for quantum network experiments on GitHub. PnPQ is a Python package for controlling optical devices in a testbed environment. Previously, researchers had to rely on vendor-specific utilities or custom scripts, which often led to issues such as unit mismatches and missing logs. PnPQ enables unified API usage and continuous logging across multiple devices, allowing for highly reproducible automation and maintainable experimental scripts.

A lecture was given at the OIST Summer School 2025. Lecture Topics Nagayama: Qunatum Network Testbed Effort in Japan Soeda: Higher-order functions and their quantum implementations for designing distributed quantum algorithms Ikuta: Photonic quantum information processing using frequency degree of freedom About OIST Summer School 2025 Overview: The school focused on quantum communications, from quantum key distribution—the most advanced and practical quantum technology—to the quantum internet, the future platform. OIST Summer School aims to build a research community to support the development of this emerging field of science and technology.

QITF Director Nagayama has been appointed as the PM for the additional proposal “Quantum Communication Networks” underneath JST Moonshot R&D Project Objective 6 “Realization of Error Tolerant General Purpose Quantum Computers for Breakthrough Economic, Industrial, and Security Development by 2050” (PD: Professor Katsuhiro Kitagawa, Graduate School of Engineering Science, Osaka University). The project title is “Scalable and Robust Integrated Quantum Communication System” Press Release by JST In that project, they will build a testbed for a general-purpose quantum communication network, which is a key technology for distributed large-scale quantum computers, and integrate hardware and software to demonstrate the principles and technologies of communication architectures and protocols with a view to actual operation.
