TNO Newly Launched Qu-STAR Project Defines the Role of Space in Global Quantum Information Networks

Insider Brief:

• TNO has launched the Qu-STAR project to advance the development of a global quantum internet, focusing on using satellites to overcome distance limitations in quantum information networks.

• The project will explore how satellite technology can provide the global connectivity required for the quantum internet, which could impact fields such as material design, pharmaceutical development, and data processing.

• TNO is collaborating with Airbus Central Research and Technology to define the architecture of this satellite-based quantum internet, contributing expertise in optics, quantum technology, and ICT infrastructure, while aligning with the Quantum Internet Alliance.

PRESS RELEASE — TNO has announced the launch of its new project, Qu-STAR, dedicated to advancing the development of a global quantum internet by using the role of satellites in quantum information networks. As noted in the release, quantum devices face distance-imposed limitations when connected through ground networks, which restrict quantum information exchange to just a few hundred kilometers. Satellites may provide a solution to realizing worldwide quantum connectivity, with TNO’s Qu-STAR project actively working towards realizing this resolution.

Quantum Internet Enabled by Space

The quantum internet may impact how we solve some of today’s most significant challenges, from material design and pharmaceutical development to predictive analysis and data processing. However, for quantum computing to reach its full potential, a global network linking quantum devices worldwide is important. Current ground-based networks face inherent limitations in transmitting quantum information over long distances. Qu-STAR seeks to explore how satellite technology can overcome these barriers and provide the global connectivity required for the quantum internet.

Kees Buijsrogge, Director of TNO Space, emphasized the importance of collaboration in this field, stating, “We believe that a collaborative, open approach will yield the best results, and we welcome other organizations to join us in this initiative.”

A Collaborative Approach to Defining a Global Quantum Network

TNO will collaborate with Airbus Central Research and Technology to define the architecture for a quantum internet that integrates satellite technology. The partnership will also align with the work of the Quantum Internet Alliance and its recently launched Special Interest Group on Space, which supports further development of satellite-enabled quantum networks. TNO will contribute its expertise in optics for laser satellite communications, quantum technology, and cutting-edge ICT infrastructure, while Airbus will bring its advanced knowledge in ground-satellite optical and quantum communication links.

Qu-STAR is the direct outcome of the letter of intent signed by Airbus and TNO at the Conférence Érasme Descartes in November 2023, an event attended by the ambassadors of France and the Netherlands.
