Introduction
As cyber threats grow more sophisticated, conventional encryption and security protocols are no longer fit for purpose. The rise of quantum computing offers a possible solution, by enhancing data encryption, network security and real-time traffic management through the use of cryptography and AI-driven quantum algorithms. At the same time, quantum AI also poses a threat, through its ability to break traditional encryption methods.

This article explores the role played by quantum AI in telecoms security, key applications of the technology, and the challenges to widespread adoption.
The Role of Quantum AI in Secure Telecommunications
1. Quantum Key Distribution (QKD) for Unbreakable Encryption
One of the most promising applications of quantum AI is quantum key distribution (QKD), a technique that enables completely secure communication. Unlike traditional encryption, which secures data through mathematical complexity, QKD uses the principles of quantum mechanics to protect data.
- Highly secure encryption: QKD ensures that any attempt to intercept quantum-encoded messages alters the data, hindering the possibility for eavesdropping;
- AI-powered quantum key management: AI optimises QKD system performance by predicting network conditions and adjusting encryption protocols accordingly;
- Government and military applications: QKD is already being deployed for high-security communications related to financial transactions, military networks and diplomatic exchanges.
2. AI-Enhanced Quantum Cryptography
Quantum cryptography is set to replace traditional encryption algorithms that are likely to soon be vulnerable to quantum computing attacks. AI plays a key role in enhancing quantum security through various means, including:
- Detecting quantum threats: AI algorithms monitor network activity for anomalies that might suggest the presence of a quantum-based cyber threat;
- Optimising quantum random number generation: AI enhances the randomness of quantum-generated encryption keys, strengthening their resilience and security;
- Adapting post-quantum cryptography standards: AI can help to transition away from classical encryption to quantum-safe cryptographic protocols.
3. Quantum AI for Network Traffic Optimisation
Quantum AI enables ultra-fast decision making, improving real-time network performance and traffic flow. This is particularly useful for future technologies, such as 6G networks. Quantum AI will improve performance in various ways, including:
- Quantum machine learning (QML): Quantum-enhanced AI models can process massive datasets faster than traditional AI, which will facilitate predictive network traffic management;
- Real-time routing optimisation: Quantum AI can adjust routing paths in real time to reduce latency and congestion in high-speed telecoms networks;
- Ultra-fast packet switching: Quantum computing speeds up data packet switching, reducing lag in next-generation networks.
4. AI-Driven Quantum Cybersecurity Solutions
As AI-based cyber threats become more sophisticated, quantum AI is being leveraged to neutralise attacks before they occur. Applications include:
- Quantum-resistant authentication: AI enhances biometric and multi-factor authentication using quantum-based security models;
- Quantum AI-powered anomaly detection: AI-driven quantum algorithms can detect unusual network behaviour and identify cyber threats in real time;
- Secure quantum communications for satellites: Quantum AI can help secure space-based telecoms infrastructure, preventing threats from hacking and signal interception in satellite networks.
Real-World Applications of Quantum AI in Telecommunications
China’s Quantum Satellite Communications
China launched Micius, the world’s first quantum satellite, in 2016 which successfully showcased the capability of QKD between space and ground stations. In January 2018 Micius enabled scientists to achieve QKD across approximately 7,600km between China and Austria. AI enhances the Micius system by optimising encryption key exchanges and predicting interference in quantum transmissions.
IBM’s Quantum-Secure Telecom Trials
IBM has been collaborating with telecom providers to test AI-enhanced quantum security for commercial telecoms networks, through the use of post-quantum cryptography to protect telecoms data. In March 2025, IBM and Vodafone announced a collaboration that will see IBM’s quantum safe technology used to enhance Vodafone secure net, an all-in-one digital security service.
