Government networks carry some of the world’s most sensitive data: diplomatic communications, defense coordination, citizen services, and critical infrastructure systems. These communications must remain confidential for decades, making public sector cybersecurity vulnerable to “harvest now, decrypt later” threats.
Quantum-secure infrastructure for sovereign networks
Build national quantum-safe communications over existing fiber infrastructure. Luxquanta’s carrier-grade CV-QKD enables governments and national infrastructure operators to protect critical communications, research networks, and digital sovereignty programs, strengthening public sector cybersecurity against future quantum threats.
National infrastructure must prepare for the quantum era
What you gain
- Long-term confidentiality for sensitive government communications.
- Stronger national cyber security against future quantum threats.
- Infrastructure-level security aligned with sovereign digital strategies.
Digital sovereignty requires trusted infrastructure
Governments across Europe, Asia, and North America are investing in national quantum communication infrastructures such as EuroQCI, connecting ministries, research institutions, and critical infrastructure operators.
Security technologies must support sovereign infrastructure that strengthens national cyber security and can operate independently of purely software-based encryption models.
What you gain
- Quantum-secure infrastructure aligned with local, regional and international initiatives such as EUROQCI.
- Stronger national technological sovereignty and national cyber security.
- Trusted communications for public institutions and critical sectors.
Public infrastructure cannot rely on experimental technology
Government networks require mature technologies that integrate with national fiber infrastructure and existing telecom operations. Quantum security must be deployable across metro and regional networks without disrupting critical public services.
What you gain
- Carrier-grade CV-QKD ready for operational infrastructure deployment.
- Integration with existing optical transport networks to support cyber security solutions for government.
- Scalable architecture for national quantum communication networks.

Juan Cambeiro, Applied Quantum Innovation, Telefónica
“The Vithas project showed how QKD can protect one of the most sensitive use cases: patient medical data.”
Sebastián Etcheverry, CTO & Co-founder, Luxquanta
“The dream of delivering the technology we were developing in our labs into a product that secures digital communication is now a reality with our QKD solution being deployed across the globe.”
Juan Cambeiro, Applied Quantum Innovation, Telefónica
“QKD adds a critical new layer of security, ensuring communications remain safe, which is fundamental for telecom operators.”
Jeison Tabares, R&D Engineer, Luxquanta
“The main innovation at Luxquanta is to use Continuous Variable QKD, as it can be deployed using standard equipment for optical communications and leverage the same optical fiber infrastructure.”
How governments approach quantum security
Supporting sovereign quantum communication infrastructure
- Start with high-value corridors connecting ministries, national data centers, and research institutions.
- Deploy quantum security over existing fiber infrastructure as part of cyber security solutions for government.
- Expand gradually across national quantum networks.
Long-term confidentiality for sovereign communications
- Protect government data, diplomatic communications, and national infrastructure systems over the long term.
- Reduce exposure to “harvest now, decrypt later” risks.
- Deploy a hardware-based root-of-trust beneath existing encryption layers.
- Implement a mature CV-QKD system aligned with national infrastructure requirements.
Proven in real national infrastructure environments
Governments and infrastructure providers are moving beyond quantum-readiness to deploy quantum communication networks protecting critical infrastructure and research systems.
