IonQ's Geneva-Seoul network pairs physical QKD with lattice-based PQC, so the same data is protected by two independent assumptions. The deployment is internal and vendor-described, so its real-world performance, key rates, and resilience aren't independently verified. For readers, it's a useful example of how enterprises may layer quantum-safe defenses during post-quantum migration, though the claims about long-distance QKD and relay integrity still need outside validation.

IonQ Deploys Intercontinental Hybrid QKD and PQC Architecture Securing Enterprise Links Between Geneva and Seoul

Quantum Computing ReportOctober 28, 20263 min read

IonQ has deployed a hybrid quantum-safe security network connecting its facilities in Geneva, Switzerland, and Seoul, South Korea. This network integrates Quantum Key Distribution (QKD) with Post-Quantum Cryptography (PQC) to protect sensitive data against emerging quantum threats. This internal commercial operationalization serves as a blueprint for multinational enterprises and sovereign institutions facing accelerated post-quantum migration deadlines.
