Financial institutions face long-term exposure to “harvest now, decrypt later” threats targeting payment systems, trading corridors, and archives.
Transaction integrity and long-term confidentiality are board-level risks.
Securing financial institutions in the quantum era
Protect high-value transactions, interbank traffic, and long-term financial records with deployable CV-QKD over existing telecom infrastructure for financial data protection.
Securing real-time transactions and long-lived financial records
What you gain
Quantum-resilient encryption in the transport layer securing:
- Interbank settlement networks
- SWIFT corridors
- Market data feeds
- Core banking backbone and data center interconnection links
- Real-time transactions and long-lived financial data.
Deploy on existing financial networks
QKD cannot realistically be deployed across hundreds of bank branches. At least today. Any solution requiring new fiber or infrastructure changes quickly becomes unviable.
What you gain
Deploy CV-QKD at the telco POP-to-POP layer across:
- HQ ↔ data centers
- Interbank metro corridors
- Cross-border financial hubs
- Quantum-safe security over existing fibre infrastructure with no network disruption.
Encryption needs physics
Post-quantum cryptography (PQC) migration is underway, but software-only cryptography does not protect the transport layer.
What you gain
A physical-layer of quantum security beneath PQC stacks.
- A layered, future-proof security architecture for financial data protection.
- Strengthened key exchange and data in transit protection across network transport.
Financial data protection for SWIFT and interbank payments
01
Reduce data in transit interception risk with CV-QKD on C-band DWDM metro backbones.
02
Future-proof interbank sensitive traffic across metro and long-haul optical networks.
03
Support compliance and audit requirements through enhanced key management and transport layer security.
Protecting links behind trades
01
Reduce manipulation risk with fresh CV-QKD keys on metro market-data backbones.
02
Protect price-distribution links across long-haul DWDM routes.
03
Enable premium connectivity with managed-telco CV-QKD on exchange on-ramps.
Quantum-safe data vaults & backup replication
01
Reduce data in transit exposure across metro vault replication with CV-QKD keys on single-fiber C-band DWDM links.
02
Protect long-term financial data and archives against future decryption risks.
03
Simplify DORA-ready controls and financial data security regulations compliance by integrating CV-QKD keys into backbone encryption and KMS.
Secure branch–HQ backbone (via Telco)
01
Reduce key-exposure risk with CV-QKD on branch-aggregator metro backbones.
02
Strengthen regional backbones with managed-telco, carrier-grade CV-QKD over metro DWDM.
03
Support resilience and banking data privacy protection by delivering CV-QKD keys into the bank WAN through telco on-ramp POPs.

“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.”
How financial institutions approach quantum-safe security
A practical path to quantum-safe finance
- Integrate with existing DWDM transport.
- Build on commercially available, carrier-grade, deployable CV-QKD technology.
- Support layered PQC + QKD architectures.
Addressing systemic risk in quantum financial services
- Reduce “harvest now, decrypt later” exposure.
- Secure high-value corridors first.
- Deploy carrier-grade CV-QKD systems.
- Protect systemic financial trust.
What quantum-safe finance makes possible
Leading banks and financial network operators today use quantum-safe backbone links to strengthen financial data protection:
Protect high-value settlement and interbank infrastructure.
Strengthen trust with regulators and stakeholders through enhanced security and resilience.
Reduce systemic risk exposure across critical financial networks.
