QTI SRL

What QTI SRL does

QTI S.r.l. is the first Italian quantum communications company, founded in October 2020 as a spin-off of CNR-INO (National Institute of Optics, National Research Council) in Florence. The company engineers, develops, and produces reconfigurable Quantum Key Distribution (QKD) architectures based on discrete-variable QKD operating in C-band and O-band configurations, layered with Post-Quantum Cryptography (PQC) in hybrid architectures for crypto-agile, quantum-resistant communications over existing fiber-optic telecom infrastructure.

QTI's product portfolio spans a full QKD stack: the Quell-X family (Quell-X core, Quell-XC bundled with Telsy MusaX encryptors, and Quell-XR for research), the Ekate crypto-agile key management platform (integrating QKD and PQC with QRNG and SDN support in a 1U form factor), the QKME key management entity for standards-based interoperability, and the QSDN software-defined networking solution aligned with ETSI GS QKD 015. The technology claims include the first long-distance hybrid QKD-PQC link (Naples-Rome), the first inter-European quantum network spanning Italy, Slovenia, and Croatia (G20 Trieste 2021), high-dimensional QKD over deployed multicore fiber at 51.5 kbps over 52 km (published in Nature Communications), and an active €7 million quantum repeaters program with CNR.

QTI monetises through direct B2B enterprise sales of QKD hardware and integration services, augmented by distribution through its TIM Group ecosystem (Telsy holds a minority stake since July 2021; Sparkle and TIM Enterprise are deployment partners). The go-to-market targets governments and defense, telecom operators, critical infrastructure operators (energy, transport, financial), and academic/research institutions, with selling motion anchored on industry-conference presence (OFC, ECOC, MWC, Submarine Networks EMEA, SPIE Photonics West, Farnborough), Italian Trade Agency-supported international pavilions, and participation in EU programs such as EuroQCI, EQUO, and QUID. Pricing is project-based and negotiated, with no public list prices — consistent with bespoke deployment of QKD systems into existing telecom and defence networks.

Direct peers

• ID Quantique: Swiss-based QKD pioneer (now owned by SK Telecom) selling discrete-variable and continuous-variable QKD systems, quantum random number generators, and key management software. Most direct global comparable to QTI's Quell-X + Ekate + QKME stack, with the same telecom and government customer base.
• Toshiba Europe (Cambridge Research Lab): Operates the Toshiba Cambridge QKD network and supplies QKD systems to BT, HSBC, and other European customers. Closely comparable in product (QKD hardware + key management) and target buyer profile (telecom operators and financial institutions), competing head-to-head in EuroQCI tenders.
• ThinkQuantum: Italian-headquartered QKD systems and quantum-safe networking company. Competes directly with QTI in the Italian and broader European market, with similar product positioning around QKD hardware and quantum key management.
• LuxQuanta: Spanish QKD vendor (spin-off from ICFO) offering CV-QKD systems and integration services to telecom operators and governments. Closely comparable European QKD peer targeting the same EuroQCI customers and use cases as QTI.
• QuantumCTek: China's leading QKD systems provider, with the world's longest commercial QKD backbone (Beijing-Shanghai) and a full QKD + PQC product portfolio. Direct peer in product scope (QKD hardware, key management, networks) and a key global competitor in critical-infrastructure deployments.
• KETS Quantum Security: UK-based developer of chip-based QKD systems targeting telecom and enterprise customers. Comparable as a smaller European QKD hardware specialist competing in the same sovereign, defense, and telecom niches as QTI.
• Quantum Xchange: US-based provider of QKD-as-a-service and key management software (Phio TX), focused on financial services, government, and healthcare. Comparable product overlap in key management and crypto-agility (QKD + PQC), though geographically distinct.

Broad incumbents

• SK Telecom (Quantum Division): Korean telecom incumbent and owner of ID Quantique, operating QKD-secured 5G and international backbone trials. Compares to QTI as a telecom-led deployer of QKD, but at vastly larger scale and with a much broader portfolio beyond quantum.
• Thales: Global defense and digital identity giant with a substantial post-quantum cryptography and quantum-safe communications portfolio. Comparable in addressing the same government/defense/critical-infrastructure buyer for crypto-agility, but as a broad incumbent rather than a QKD specialist.

Emerging players

• HEQA Security: Israel-based QKD startup commercializing QKD systems and quantum-safe networking products for telecom and government customers. Comparable early-stage QKD hardware peer with overlapping target segments and similar reliance on government/defense pilots.
