QEYnet develops a low-cost satellite quantum-key-distribution receiver intended to support orbital rekeying and key exchange between ground locations. Its proposed architecture supplies raw keys for customer integration and separates dedicated/shared satellite service concepts from the cryptographic payload. A terrestrial free-space QKD system was delivered to NRC for experiments in 2024; CSA-supported space testing remains a distinct development programme through December 2026. Implementation side channels and key-management integration require assessment.
Technical detail
Core features
Space QKD receiver for planned orbital rekeying demonstrations
Raw-key output for customer cryptographic integration
Shared and dedicated satellite-service architecture concepts
NRC terrestrial free-space QKD delivery reported December 2024
Quantum key distribution
QKD
Free-space optics
Satellite cybersecurity
Quantum communications
Use & integration
Recorded applications
Satellite communications rekeying
Post-quantum security experiments
Long-distance quantum networking
Government security testing
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Terrestrial experimental system delivery is supplier-reported; CSA independently documents a funded orbital demonstration and intended outcomes, without reporting a completed flight or global commercial network.
Commercial availability
Engagement is available for QKD system development and trials. Confirm flight status, optical ground segment, link budget, secret-key rate, authentication and key-management interfaces before treating the offering as an operational satellite service.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
Satellite-enabled key distribution could support secure long-distance communications to remote northern sites, subject to optical-link availability and successful orbital demonstration.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
