What KEEQuant does

KEEQuant GmbH is a privately held German quantum-security startup founded in 2020 and headquartered in Fürth, Bavaria. The company develops Continuous-Variable Quantum Key Distribution (CV-QKD) systems and a Key Management System (KMS1) that provide physics-based, quantum-computer-resistant encryption keys for telecom operators, government agencies, critical infrastructure operators, research networks, and confidentiality-sensitive enterprises. Its core differentiator is that its CV-QKD implementation, built on standard coherent telecommunication components, is the only QKD technology described as fully integrable onto photonic integrated circuits (PICs), enabling chip-scale form factors and telecom-equivalent unit economics.

The product portfolio consists of the Andariel QKD system (rack-mounted and chip-scale variants supporting 16 dB channel loss / 80 km reach), the KMS1 key management appliance built on ETSI QKD standards with hybrid Post-Quantum Cryptography integration, and an emerging free-space QKD with Li-Fi stack. Technical milestones include the DemoQuanDT 900+ km quantum-secured link in Deutsche Telekom's live fiber backbone (2024), 64 Tbps classical-data coexistence over 75 km on standard G.652.D fiber (SEQRET, 2026), and the March 2026 unveiling of commercial-grade chip-scale QKD with first customer shipments planned later in 2026.

KEEQuant operates a consultative, quote-based enterprise sales motion targeting telecom carriers, data center providers, and government/critical-infrastructure buyers, with no public pricing or channel partners. Revenue is currently driven primarily by EU- and German-government-funded consortium projects (SEQRET, QuINSiDa, DemoQuanDT, QuNET+ProQuake), with hardware sales, professional integration services, and future PIC licensing as the long-term monetization vectors. The company is 100% EU27-financed and positions itself as a sovereignty-compliant supplier for European government, defense, and critical-infrastructure customers.

Revenue model

1. QKD Hardware Systems: Sale of quantum key distribution systems (Andariel Testbed Series) as rack-mounted or chip-scale hardware appliances for fiber-optic networks. Revenue recognized upon delivery of physical QKD devices. The commercial-grade chip-scale QKD announced in March 2026 will begin shipments to first customers later in 2026.
2. Key Management System (KMS1): Sale of the KMS1 Key Management System appliance that manages cryptographic key lifecycle and distribution over complex network topologies. Sold alongside QKD systems to enterprise and telecom customers requiring quantum-secure key management.
3. Professional Services and System Integration: Engineering integration services and consulting for QKD deployment into existing telecom networks and critical infrastructure environments. Provided as part of EU-funded project delivery (SEQRET, QuINSiDa, DemoQuanDT) and direct enterprise engagements, including certification-readiness and customer-centric network integration.
4. Future Licensing and PIC Integration: Long-term vision to embed CV-QKD functionality into standard telecom transceivers as a commodity feature, potentially creating licensing revenue from PIC manufacturers and telecom equipment vendors integrating quantum capabilities into existing products.

Core offering

KEEQuant develops and sells Continuous-Variable Quantum Key Distribution (CV-QKD) systems and a complementary Key Management System (KMS1) for fiber-optic communication networks. The Andariel QKD system generates cryptographic key pairs using standard coherent telecom technology operated at the quantum limit, and the company is commercializing a chip-scale QKD product that integrates all major optical building blocks onto photonic integrated circuits for scalable, cost-efficient quantum-secure communications.

Product overview

KEEQuant offers a comprehensive suite of quantum security products covering both the physical QKD layer and the key management layer. The core product portfolio consists of the Andariel QKD system (based on Continuous-Variable QKD technology using standard coherent telecommunication operated at the quantum limit) and the KMS1 Key Management System (for lifecycle management and distribution of cryptographic keys over complex network topologies). The recently launched chip-scale QKD technology integrates all major optical building blocks onto photonic chips, representing a transition from rack-sized systems to miniaturized, scalable quantum-secure communication solutions. The company is working toward full integration of CV-QKD functionality onto single Photonic Integrated Circuits (PICs).

Products and services

• Andariel (Quantum Key Distribution System) Andariel is KEEQuant's flagship Continuous-Variable Quantum Key Distribution (CV-QKD) system that generates cryptographic key pairs within an optical fiber network using standard coherent communication technology operated at the quantum limit. The Andariel Testbed Series supports 16 dB channel loss (≈80 km in standard telecom fiber), enabling metro, regional, long-haul core, and data center interconnect networks. It is sold to telecom operators, data center providers and critical infrastructure operators who need physics-based, quantum-computer-resistant key exchange.
• KMS1 (Key Management System) KMS1 is KEEQuant's Key Management System appliance that gives network operators control over cryptographic keys across their full lifecycle and interfaces, and distributes keys over complex network topologies. It includes hybrid Post-Quantum Cryptography (PQC) integration for future-proof, defense-in-depth key management and is built on ETSI QKD standards. KMS1 is sold alongside Andariel to enterprise, telecom and critical-infrastructure customers that require operator-controlled, quantum-safe key management.
• Commercial-Grade Chip-Scale QKD Chip-Scale QKD is KEEQuant's commercial-grade, photonic-integrated QKD platform that integrates all major optical building blocks—transmitter/receiver lasers, modulation, receiver optics, and detection—onto photonic chips using standard photonic integrated circuits (PICs). It replaces bulky optical assemblies with compact photonic architecture, enabling repeatable packaging, miniaturized form factor, telecom-grade producibility and cost efficiency. The long-term roadmap is to host 100% of CV-QKD functionality onto a single PIC; first customer shipments are planned for later in 2026.
