Quantum Key Distribution Market Trends

The global quantum key distribution market size was estimated at USD 446.0 million in 2024 and is expected to grow at a CAGR of 33.5% from 2025 to 2035. As quantum computing advances, traditional encryption methods will become increasingly vulnerable. This shift highlights the growing need for quantum-safe encryption techniques. Quantum key distribution (QKD) offers a solution to secure communications against future quantum computing threats. It is especially important for safeguarding sensitive information in infrastructure, government, and defense industries.

The project focuses on the development and deployment of QKD to protect against future cybersecurity threats. For example, in January 2025, Thales Alenia Space, a French aerospace firm, and Hispasat launched the development of the quantum key distribution system from geostationary orbit. The project will generate unbreakable encryption keys through satellite-based quantum communication, placing Spain at the forefront of the European Quantum Communication Infrastructure (EuroQCI) initiative.

QKD integration with a pre-existing fiber optic network demonstrates the tendency of embedding superior quantum technologies within existing infrastructure. It allows quantum security solutions to be easily integrated across different sectors. With advancing quantum technologies, sectors will see an increased integration of these into their networks for ensuring communications security. The shift provides a lead example for industries to strengthen their networks against the impending cyber attacks. For example, in October 2024, Netherlands-based telecommunications equipment provider Eurofiber partnered with Q*Bird to incorporate QKD technology into Eurofiber's widespread fiber optic infrastructure. This partnership strengthens data protection across industries including logistics, finance, and government, offering a strong defense against future cyber attacks, including attacks from future quantum computing capabilities.

The rollout of 5G networks is propelling the requirement for greater security solutions, which has opened a door for quantum key distribution (QKD) to fill those gaps. With increased growth of 5G networks, new weaknesses are added and older ways of encryption lose efficacy against the evolving cyber threat landscape. QKD provides security that is theoretically invulnerable to attack by quantum computing, and that makes it a vital asset to secure communications on 5G networks.

The integration of QKD in 5G networks can give secure key exchange, keeping the data encrypted when being transmitted. It is crucial in industries like telecommunication, finance, and healthcare, whose survival depends on the integrity of the sensitive information. Businesses are searching for solutions to integrate QKD with 5G so they can future-proof their systems from emerging cybersecurity threats. As 5G starts to deploy worldwide, the alignment of QKD with 5G networks is likely to be a backbone of secure communications.

The increasing use of satellite-based quantum key distribution (QKD) is revolutionizing world communication security. Satellite-based QKD enables secure exchange of keys over long distances, circumventing the limitations of ground networks. QKD systems with conventional setup are constrained by the transmission range of optical fibers, thus making satellites a convenient option for worldwide access. Successful tests of satellite-based QKD indicate its promise for secure communication. This technology guards sensitive information for the military, government, and commercial industries. Satellites offer a solution to the threat of land-based network interception. As satellite technology improves, satellite-based QKD is likely to strengthen cybersecurity. The future of QKD is bright, with satellite-based solutions likely to transform international communication security.
