Technology domains, maturity levels, initiative models, and strategic positioning across the global quantum networking landscape. Includes adjacent technologies (computing, sensing, PQC) for context.
The quantum networking space spans seven domains, four core and three adjacent. Click initiative tags to highlight across tabs.
Calibrated to observed deployment states in quantum networking. Most initiatives cluster at Level 1-2. Level 3 (operational) is rare and notable.

How initiatives are structured, funded, and governed. Determines sustainability, access, incentive alignment, and what kinds of research are possible.
The most significant structural development: the convergence of three previously separate tracks into a unified quantum-safe communications architecture.
Deployed, commercial products exist, distance-limited to ~200 km without repeaters. Physics-based security.
Deployed, software-only, NIST standards finalised 2024. No physics layer. Algorithmic security -- could be broken by future mathematical advances.
Lab-stage (TRL 1-2). Distance-enabling. First viability milestone Feb 2026 (USTC: 10 km, 550 ms coherence, memory lifetime > establishment time).
The procurement decision is not "QKD or PQC" -- it is "when and how to layer both, at what cost, given the repeater timeline." Kirq's Blueprint 7 (Nokia/Numana, validated February 2026) is the first demonstrated answer: PQC + QKD integrated into existing multi-vendor networks without full system replacement.
The satellite layer (QEYSSat, HYPERSPACE, Micius) provides a parallel distance-extension path: fiber for metro/regional, satellite for inter-city and trans-continental, repeaters (eventually) for high-bandwidth long-haul.
PQC migration is mandatory (Canada 2035 deadline). QKD adds a physics layer for highest-sensitivity links. Plan for both.
Memory-based repeaters are 5-10 years from field deployment. Satellite bridges the gap. Architecture decisions made now should not depend on repeaters.
Open testbeds (Kirq, ABQ-Net) let organisations test integration before committing. This is the equivalent of a cloud sandbox for quantum-safe migration.
Where quantum networking capabilities concentrate, and what the funding asymmetries imply for national positioning.
Dominant testbed diversity. DC-QNet (defence), IEQNET/ArQNet (DOE/academic), ABQ-Net (commercial), QUANT-NET (computing), NG-QNet (standards). DARPA QBI for utility-scale quantum computing.
Strategically positioned: G7/Five Eyes, transatlantic geography, satellite program. Kirq only operational testbed. NRC Ottawa: quantum comms research, free-space QKD link (5.4 km NRC-UOttawa). Strong talent base (Waterloo, Sherbrooke, SFU, UOttawa).
EuroQCI building pan-European infrastructure (terrestrial + satellite). QIA Demonstrator at QuTech/Delft -- first quantum network OS (March 2025). UK NQCC with 500M GBP new funding. NATO Transatlantic Quantum Community.
China leads experimentally (USTC repeater breakthrough Feb 2026, Micius satellite 2017, Beijing-Shanghai backbone). Japan: $420M testbed infrastructure. South Korea: SK Telecom commercial QKD.
The standard Peerlabs analytical framework applied to the quantum networking landscape as of March 2026.
QKD key generation, entanglement distribution (metro), clock synchronization (sub-picosecond over 53 km) are demonstrated. Memory-based repeaters hit first viability milestone (Feb 2026 USTC: coherence > establishment time). Hybrid QKD+PQC integration validated (Blueprint 7). Satellite QKD demonstrated (Micius 2017), Canadian QEYSSat launching late 2026.
Primary drivers: defence/intelligence (harvest-now-decrypt-later), finance, telecom infrastructure modernisation, healthcare data protection. Open testbeds (Kirq, ABQ-Net) enabling enterprise experimentation. Commercial QKD deployed in China and South Korea; limited elsewhere. Enterprise adoption pre-commercial for most quantum networking capabilities.
Dark fiber is the foundation; availability varies by geography. Classical-quantum coexistence on shared fiber demonstrated. SDN control planes prototyped (ArQNet, IEQNET). Standards immature (ETSI ISG QKD, ITU-T). Interoperability between testbeds not yet demonstrated. Satellite adds pointing/eclipse constraints.
Talent concentrated in few hubs (Waterloo, Sherbrooke, Delft, Hefei, Oxford, Boulder). Pipeline constrained -- cross-disciplinary skills needed (quantum physics + networking + security). Policy signals strengthening: Canada PQC 2035, NATO strategy, G7 commitments. Ottawa telecom heritage (Nokia, Ciena, Ericsson, Nortel alumni) is a distinct asset.
