KEEQuant Launches Commercial-Grade Chip-Scale QKD Technology

KEEQuant has announced the commercial launch of chip-scale Quantum Key Distribution (QKD) technology based on photonic integration. This transition replaces conventional discrete optical assemblies with Photonic Integrated Circuits (PICs), aimed at reducing system complexity and hardware costs for telecom and data center operators. The company is scheduled to begin initial hardware shipments to customers in late 2026, representing a transition from experimental pilot programs to standardized network infrastructure.

The technical milestone consists of integrating essential optical building blocks—transmitter and receiver lasers, modulation units, and receiver detection optics—onto a unified photonic chip architecture. This design enables repeatable packaging and standardized manufacturability for large-scale deployments while ensuring compatibility with current fiber optic networks and existing encryption protocols. The move to a chip-scale format provides the engineering foundation for hybrid security models that combine QKD hardware with dedicated Key Management Systems (KMS).

Development of this technology was funded through the SEQRET project under the European Union’s Digital Europe Programme within the EuroQCI framework. The initiative focuses on the industrialization and certification readiness of quantum-secure communications for European telecommunications infrastructure. KEEQuant’s systems are designed to support hybrid applications of QKD and Post-Quantum Cryptography (PQC) to protect sensitive data flows against cryptanalytic threats posed by future quantum computational capabilities.
