Quantum Optics Jena

What Quantum Optics Jena does

Quantum Optics Jena GmbH (QOJ) is a privately held German deep-technology company founded in 2020 and headquartered in Jena, Thüringen, with a North American subsidiary (Quantum Optics Jena Corporation). The company designs and sells entanglement-based Quantum Key Distribution (QKD) systems that generate symmetric encryption keys from correlated photon pairs, providing tap-proof communications whose security derives from physical laws rather than mathematical complexity. Its modular 'Elvis' QKD platform integrates three proprietary building blocks: the 'HD' entangled photon pair sources (available at 800 nm, 1300 nm O-Band, and 1500 nm C-Band wavelengths, with >97% fidelity and >40-50 million pairs/sec), the 'PAM' polarization analyzing and control modules (with patent-protected automated polarization control), and the 'LLC' software suite implementing the BBM92 protocol with support for SKIP and ETSI QKD 014, delivering QBER below 9% and secure key rates above 1,500 bits/s at 10 dB loss. The portfolio also covers satellite/space QKD payloads and a PIC-PAM silicon-photonics integration project aimed at an SFP-like chip-scale module.

The company operates a direct enterprise field-sales motion targeting data-center operators, critical infrastructure operators, and telecommunications providers across Europe and North America, complemented by professional services for network planning and protocol integration. Revenue is generated primarily through hardware sales of QKD systems and sub-components (HD sources, PAM modules) plus customized consulting, with quote-based, project-specific pricing for enterprise deployments. QOJ has demonstrated its technology live with regional telecom operator envia TEL and DE-CIX in Germany, is backed by EUR 8.5 million in Series A funding led by Join Capital (Sept 2024), and is a participant in the EU/Thüringen-co-financed PIC-PAM consortium. The company employs 11-50 people and is led by Managing Directors Dr. Oliver de Vries and Dr. Kevin Füchsel.

Core offering

Quantum Optics Jena develops and sells entanglement-based Quantum Key Distribution (QKD) systems under the "Elvis" brand, combining proprietary HD entangled photon pair sources, PAM polarization analyzing and control modules, and the LLC quantum protocol implementation based on BBM92. The portfolio covers fiber-network QKD at 800 nm (short-distance), 1300 nm and 1500 nm (long-distance telecom bands), satellite/space QKD payloads, and a supporting QKD software suite, sold as customized, modular building blocks to enterprise data-center, telecom, and critical-infrastructure customers.

Product overview

Quantum Optics Jena is a quantum technology company that develops and delivers Quantum Key Distribution (QKD) systems based on entangled photons for cybersecurity solutions. The product portfolio is organized as a modular platform architecture centered around the 'Elvis' QKD systems, which consist of three core integrated components: the 'HD' entangled photon pair source, the 'PAM' polarization analyzing and control sub-systems, and the proprietary 'LLC' quantum protocol implementation based on the BBM92 protocol. The company offers fiber-based network solutions (Elvis 800 for short-distance at 800nm wavelength, Elvis 1500 for long-distance at 1300-1550nm), satellite and space-based QKD payloads, and an advanced software suite supporting SKIP and ETSI QKD 014 protocols. The HD product line provides entangled photon pair sources at 800nm, 1300nm, and 1500nm wavelengths for various network configurations.

Scale indicators2 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• MagiQ Technologies: US-based QKD vendor focused on government, defense, and critical infrastructure customers. Comparable target segments and product category, though with a primarily North American commercial footprint.
• KETS Quantum Security: UK startup building chip-integrated QKD systems. Highly comparable to QOJ's PIC-PAM roadmap and a credible competitor in the European chip-scale QKD race.
• SpeQtral: Singapore-based company developing space-based QKD systems and satellite payloads. Closely comparable to QOJ's satellite QKD payload offering and emerging as a regional competitor in APAC.

Direct peers

• LuxQuanta: Spanish startup offering CV-QKD systems for telecom operators and enterprises. A direct European peer competing for the same EU-funded QKD pilots and critical infrastructure deployments as Quantum Optics Jena.
• ID Quantique: Swiss-based pioneer and global leader in QKD systems and quantum-safe networking, offering entanglement- and prepare-and-measure-based QKD products to enterprises, governments, and telcos. Most direct competitor to Quantum Optics Jena's Elvis systems.
• QuintessenceLabs: Australian quantum cybersecurity company offering QKD and quantum random number generation products to governments and enterprises. Comparable product mix and enterprise/critical infrastructure GTM.
• QuantumCTek: China's leading commercial QKD vendor, operating the Beijing-Shanghai backbone and supplying QKD equipment to government, finance, and telecom customers. Comparable product portfolio (fiber QKD systems, key management) and similar target verticals.

Broad incumbents

• Toshiba (Cambridge Research Laboratory / Quantum Technology Division): Operates one of the most advanced QKD R&D programs globally and has deployed field QKD links with BT, Verizon, and other carriers. A broad incumbent whose QKD portfolio directly overlaps with QOJ's enterprise and telco use cases.
• Cisco (Outshift by Cisco): Cisco's Outshift incubation arm is investing in quantum networking and QKD infrastructure, positioning it as a broad incumbent that could integrate QKD into mainstream enterprise networking gear — a structural threat to specialist vendors like QOJ.

Others

• Fraunhofer Institute for Applied Optics and Precision Engineering (IOF): Jena-based applied research institute with deep expertise in photonics and quantum optics. Both an investor (via FTTF) and a partner in the PIC-PAM consortium, Fraunhofer IOF is an enabling ecosystem participant rather than a direct competitor.
