The adoption of quantum computing in telecom networks has accelerated in 2025. This shift wasn’t widely predicted earlier this year when the spotlight was on AI and Agentic AI. But now, telecom companies are making significant moves to use quantum tech for innovation and better network security.

1. SoftBank’s Breakthrough in RAN Optimization

Three weeks ago, I shared updates on how operators like Vodafone, BT Group, SK Telecom, and Verizon are exploring quantum computing for different use cases.

This week, SoftBank made headlines by announcing a successful proof of concept in Tokyo. They used an Ising machine—a type of quantum computer—to fine-tune radio base station settings. The result: a 10% increase in 5G downlink speed and up to 50% more data capacity using carrier aggregation (CA). SoftBank also said they plan to use this tech not just to improve network architecture but also to make operations more efficient, aiming for smoother and higher-quality services.

2. Europe Leads in Quantum-Safe Networking 

TelecomTV recently shared findings from the DSP Leaders’ “Quantum-Safe Networking Market Perception Report.” It highlights how telecoms are preparing for a future where quantum computers could be used by hackers to break into systems. Today’s encryption methods won’t hold up against such threats.

To stay ahead, operators are investing in quantum-safe networking, which includes:

• Quantum Key Distribution (QKD)
• Post-Quantum Cryptography (PQC)

** The key takeaways **

• • 7 of the top 10 leaders in quantum-safe networking are based in Europe.

• Most surveyed telecom operators aim to implement these security measures within the next four years.

Questions to leaders – As quantum computing gains momentum in telecom, how are you aligning it with your network transformation strategies? Are you actively exploring its potential, or risking being left behind in this emerging wave of innovation?
