Monday (telco diary) | Q-Day is nigh – join the telco wake-up call

From the newsletter: The Quantum Safe Networks Forum highlights telecom’s urgent race toward post-quantum security, with telcos exploring quantum-safe networks, migration strategies and standards to prepare for Q-Day threats.

A timely event reminder that the Quantum Safe Networks Forum is next week (July 14) – and you should be there. Because Q-Day, when quantum computers can crack today’s standard encryption, is around the corner, some time after 2028. The telco industry is at the centre of the scramble to manage the response. This is not theoretical; encrypted traffic being harvested today could be decrypted tomorrow, turning long-term data security into a live infrastructure problem.

Which is why operators are increasingly exploring quantum-safe networks as a service – not just to shore up existing defences, but to build a new security layer into the fabric of connectivity itself. Telefónica is at the forefront of that push and will be a host partner at the forum, alongside speakers from AT&T, MetTel, Singtel, Orange Business, and others – all bringing operator realities into sharp focus, around how to migrate carrier-grade networks without breaking them.

The agenda cuts to the heart of it: post-quantum cryptography for telecom infrastructure, 5G vulnerabilities, migration strategies, and the harder question of standards alignment across a fragmented global ecosystem. Add in updates from R&D programmes and early deployment case studies, and the forum becomes less about future speculation and more about operational readiness. Quantum may feel somewhat distant – but it is closing fast, the telco clock is ticking.
