Geneva launches its first quantum communication network

Geneva has inaugurated its first quantum communication network, marking a major step forward in the development of next-generation data and time-transfer technologies. The Geneva Quantum Network (GQN) is the result of a collaboration between the University of Geneva (UNIGE), CERN, HEPIA, ID Quantique, Rolex, and the Cantonal Office for Information Systems and Digital Technology (OCSIN). The project was officially unveiled during the Swiss Quantum Industry Day in the presence of State Councilor Delphine Bachmann.

Built on OCSIN’s fiber optic infrastructure, the GQN spans 262 kilometers, connecting key research and industry sites across the canton. The network provides a large-scale experimental platform for quantum communication, metrology, and synchronization, positioning Geneva as a national and international hub for quantum innovation.

Public-private collaboration driving research and education

Quantum communication exploits the properties of light particles, or photons, to enable ultra-secure data transfer and highly precise time measurement. Dedicated networks such as the GQN are essential to test and deploy these technologies in real-world conditions. The initiative focuses on four key objectives: scientific progress, education and training, coordination and visibility, and public engagement.

“The launch of the GQN is a magnificent example of the impact that public-private partnerships can have,” said Delphine Bachmann, State Councilor in charge of the Department of Economy and Employment. “Quantum technologies have immense potential to bring about solutions that will make our industrial sector even more dynamic.”

In its initial phase, the network will connect UNIGE, CERN, and HEPIA to distribute entangled photons and deploy quantum key distribution (QKD) systems developed by ID Quantique. The network also integrates ultra-precise time signals provided by Rolex’s optical rubidium atomic clock and synchronization systems designed by CERN.

Western Switzerland, a fertile ground for quantum innovation

The launch of the Geneva Quantum Network reflects a broader dynamic unfolding across Western Switzerland. Harnessing the promise of emerging quantum technologies, the region is positioning itself as a pivotal hub in this transformative field. Quantum technologies, based on the principles of quantum mechanics, open new frontiers in computing, communication, and sensing, enabling breakthroughs in data security, precision measurement, and scientific discovery.

The region offers an exceptional ecosystem where academia, industry, and public authorities work closely together. Supported by world-class universities, cutting-edge research centers, and strong industrial partners, Western Switzerland provides an ideal environment for quantum research and application. Its long-standing expertise in microengineering, optics, and information technology aligns perfectly with the intricate demands of quantum innovation.

Academic leadership and industry impact

The University of Geneva is internationally recognized for its pioneering work in quantum communication and cryptography. Through the Geneva Quantum Centre and collaborations with industry leader ID Quantique, UNIGE has transformed academic research into practical applications for secure data transmission. ID Quantique, itself a spin-off from the university, has become a global reference in quantum-safe cryptography and communication.

Meanwhile, the École Polytechnique Fédérale de Lausanne (EPFL) plays a central role through its Center for Quantum Science and Engineering (QSE Center), fostering interdisciplinary research and training the next generation of quantum engineers. CERN, though best known for its particle physics research, also contributes through its Quantum Technology Initiative (QTI) and cutting-edge infrastructure supporting metrology and synchronization experiments.

National and international collaborations

These regional strengths are amplified by Switzerland’s national programs such as the Swiss Quantum Initiative (SQI) and the Swiss Quantum Commission, which aim to consolidate the country’s leadership and strengthen collaboration between research and industry. Western Switzerland’s active participation in European programs, including the Quantum Flagship, ensures that its contributions extend far beyond national borders.

Together, these initiatives reinforce Western Switzerland’s position as a leading European hub for quantum research, innovation, and industrial development.
