Problem
Conventional cryptographic keys are vulnerable to future attacks by large-scale quantum computers, creating a looming security risk for data transmitted over existing fiber networks. Deploying traditional quantum key distribution (QKD) solutions is hindered by bulky optical hardware, high costs, and complex integration requirements, limiting widespread adoption.
Solution
KEEQuant delivers chip‑scale continuous‑variable QKD (CV‑QKD) systems that operate at the quantum limit using standard coherent telecommunication technology. By integrating all major optical components—lasers, modulators, receivers, and detectors—onto a single photonic integrated circuit, the solution achieves a compact, cost‑efficient form factor suitable for existing fiber infrastructures. The accompanying Key Management System (KMS) provides automated lifecycle handling and flexible distribution of quantum‑generated keys across complex network topologies. Compatibility with current telecom equipment and encryption protocols enables operators to upgrade to quantum‑secure communications without extensive redesign. This combination of miniaturized hardware and software control makes quantum‑safe key exchange practical for large‑scale, real‑world deployments.
Target Audience
Primary customers are telecom operators, data‑center providers, and owners of critical infrastructure who require quantum‑resistant key exchange for their fiber‑based networks.
