Market stakeholders in the telecoms industry are predicted to invest over $6 billion on developing and implementing quantum key distribution between 2025 and 2030, according to Juniper Research.

Quantum key distribution is a communication method that leverages quantum mechanics to create encryption keys that are unable to be intercepted by fraudulent players, ultimately increasing the security of network transmissions.

This substantial investment will be driven by the acceleration of quantum computing and its potential use by fraudsters. With traditional network encryption methods vulnerable to quantum computing, this investment is vital to protect the security of telecoms networks, notably for enterprise users.

Quantum Hardware a Major Cost for Operators

The report from Juniper Research found that the scalability of quantum key distribution solutions is the most prominent concern for network operators as they deploy nationwide quantum-secure networks.

Quantum key distribution hardware, such as quantum random number generators that create encryption keys, is expected to be the largest quantum key distribution cost, as operators must implement quantum-capable hardware over their extensive networks.

The research also anticipated that, as these networks grow, operators must implement tools that enable the real-time management of quantum cryptography.

It identified AI-driven network management platforms, which provide optimised traffic routing and resource allocation, and quantum network simulators as two key value-added offerings.

“As network operators increasingly monetise their networks through enterprise services, it is imperative that they provide protection against quantum threats in the future,” research author Michelle Joynson said.

“By investing in quantum key distribution now, operators position their networks best to capitalise on the growth of enterprise network users.”
