PIONIER-Q: Construction of Cross-Border Quantum Key Encryption Connections

PIONIER-Q: Construction of Cross-Border Quantum Key Encryption Connections

A key stage in the construction of the nationwide quantum key infrastructure, connecting High-Performance Computing centers within the PIONIER network, has been completed. During the March meeting with the European Commission, the test results were successfully summarized, and a strategy for further expansion of cross-border connections was presented.

In March, the final summary of the PIONIER-Q project results was conducted with representatives of the European Commission. The meeting showcased the full scope of completed tests and their outcomes, which confirmed the infrastructure’s readiness for secure data transmission using QKD (Quantum Key Distribution) technology.

The network, whose construction was finalized at the end of 2025, is based on dedicated fiber-optic connections of the PIONIER consortium. During the works, a wide range of use cases was verified—from short-distance local links to advanced backbone configurations between distributed computing centers.

The project enabled the development of unique competencies in integrating quantum technologies with existing network infrastructure. The acquired experience forms the foundation for the next phase of work, which involves building cross-border quantum key encryption connections. This project exemplifies close collaboration within the Polish scientific community, setting directions for the future development of secure quantum connectivity in the region.
