Critical infrastructure operators (power, water, gas, rail) face growing state-level cyberattacks. OT and SCADA links carrying command and telemetry data must remain confidential for decades.
Quantum security for critical infrastructure protection
Deploy carrier-grade CV-QKD on existing fiber networks to protect OT communications, strengthen critical infrastructure protection, and reinforce national resilience.
Critical infrastructure is targeted
What you gain
- Protect SCADA, ICS, and control-center links with quantum-resilient encryption at the communication layer.
- Strengthen national resilience by securing operational routes between substations, pumping stations, and control centers.
- Ensure long-term confidentiality of telemetry, grid analytics, and operational command traffic.
Security must fit operations
OT environments evolve slowly. Multi-year grid-modernization cycles and strict uptime requirements make disruptive upgrades impractical. If quantum security requires new fiber, redesign, or downtime, adoption will stall at the pilot stage.
What you gain
- Add CV-QKD on existing fiber without disrupting live OT traffic.
- Fit current architecture and upgrade timelines.
- Scale quantum-safe protection across metro and regional infrastructure without added complexity.
Infrastructure needs industrial-grade security
Critical infrastructure operators need systems built for reliability, compliance, and regulatory scrutiny. Prototype or research-grade solutions add risk and do not fit resilience mandates.
What you gain
- Deploy commercial-grade CV-QKD built for real critical infrastructure environments.
- Support NIS2, CER, and broader critical infrastructure cybersecurity requirements.
- Reduce long-term systemic risk with operational maturity and lifecycle fit.

“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 critical infrastructure gets quantum-ready
Supporting your grid-modernization journey
- Start with priority links: control centers, backbone substations, and WAMS routes.
- Integrate with existing optical networks through single-fiber coexistence.
- Align deployment with upgrade cycles and compliance programs.
Building long-term resilience
- Reduce “harvest now, decrypt later” exposure on high-value control links.
- Deploy a mature CV-QKD system designed for operational continuity.
- Strengthen long-term infrastructure resilience without waiting for disruptive infrastructure redesign.
What infrastructure leaders are proving
Critical infrastructure network protection with quantum security has already moved from theory to deployment. Luxquanta delivers deployment-ready CV-QKD built for real operational environments.
National quantum infrastructure programs
Luxquanta’s Nova lq® has been validated in publicly funded quantum communication initiatives, confirming stable key generation over metro-scale distances and coexistence with active DWDM traffic. These validations show that quantum-safe protection works within real infrastructure constraints.
Multi-sector infrastructure pilots
Quantum-secure links have been demonstrated with telecom operators and technology partners, validating secure interconnection between critical facilities and data environments. These pilots show how operators can strengthen backbone assurance while maintaining operational continuity.
Vithas
Luxquanta partnered with Telefónica and Vithas to deploy quantum-secure connectivity between two hospitals in Madrid, protecting communications across critical healthcare infrastructure. Using Luxquanta’s CV-QKD technology, encryption keys are generated through quantum processes and distributed over dedicated fiber links to secure sensitive operational data. The project highlights how quantum-safe networks can strengthen the resilience of critical infrastructure sectors facing future quantum computing threats.
