Merqury Cybersecurity, a Malta-based quantum cybersecurity company, has joined forces with Juniper Networks, LuxQuanta, and lyntia to demonstrate a quantum-secured connection between on-premises data centres and Amazon Web Services (AWS).

Juniper Networks is a leader in networking technology, LuxQuanta specialises in quantum encryption over existing fibre-optic infrastructure, and lyntia is a top-tier fibre-optic provider based in Spain.

This collaboration of these four companies, forms part of a broader initiative to safeguard critical data transmissions against the rising threat posed by quantum-enabled cyberattacks.

Quantum technology uses principles from the physics of quantum mechanics, to develop new devices and systems.

At the core of the initiative, Merqury Cybersecurity contributed its advanced Post-Quantum Cryptography (PQC) solutions and key management technologies. These were combined with LuxQuanta’s Quantum Key Distribution (QKD) systems, lyntia’s fibre infrastructure, and Juniper’s AI-native security portfolio to establish an end-to-end quantum-resilient communications architecture.

A live demonstration was conducted at the AWS Direct Connect location in Madrid, Spain.

It showcased a point-to-multipoint quantum network connecting multiple data centres through lyntia’s fibre network, staged with real traffic from lyntia’s operational systems. LuxQuanta’s QKD hardware was integrated with Juniper’s encryption technologies to secure the optical transport layer, while Merqury’s PQC stack provided cloud-level data protection, delivering a multi-layered cyber defence strategy.

Noel Farrugia, Chief Technology Officer at Merqury Cybersecurity, expressed how “this collaboration marks a big step forward in showing how quantum technologies can be integrated into real-world telecom infrastructure.”

He added that, thanks to the combined expertise of the four companies involved, these advanced concepts are now moving from theory to practical application.

“This is an important milestone in Merqury's mission to build future-ready, quantum-secure communication systems,” he continued.

Eduardo Duato, Chief Technology and Innovation Officer at lyntia, Sebastian Etcheverry, Chief Technology Officer at LuxQuanta and Raj Yavatkar, Chief Technology Officer at Juniper Networks, all expressed their enthusiasm for the collaboration, highlighting the critical role of cutting-edge quantum technologies in protecting customer data.

This development reflects Malta’s ongoing involvement in European digital infrastructure initiatives, including PRISM EuroQCI, and supports the broader progress toward quantum-resilient systems across the continent.
