Quantum Articles – Telecommunications

A trade body published a vendor-contributed document, and the one exhibit anyone could verify turned out to misreport the report it names. What that costs the operators who will quote it in board papers ...

Cloudflare made hybrid ML-KEM generally available for IPsec site-to-site tunnels, with Cisco 8000 routers and FortiOS 7.6.6 interoperating, four years after post-quantum key exchange reached TLS ...

IonQ and Florida LambdaRail signed a master service agreement for a three-node QKD corridor over existing research fiber from Palm Beach County to Miami-Dade, the first phase of a planned statewide network ...

An increasing number of telecom leaders have been pinging me lately about quantum readiness. And frankly, that’s exactly what they should be doing. New regulations and mandates are emerging left and right (in various jurisdictions and across the industry) requiring critical infrastructure to become quantum-safe in the coming years. As someone who used to run global telecom cybersecurity practices - and served as interim CISO for several telcos - I can attest that preparing a large telecom for the post-quantum era is far from a trivial “patch update.” In fact, transitioning a telco to post-quantum cryptography (PQC) is an enormous, multi-year effort - likely “the largest and most complex digital ...

Cybersecurity lore often paints Q-Day (the moment a quantum computer cracks RSA/ECC encryption) as an instant "Quantum Apocalypse" where every system gets hacked immediately. Planes falling from the sky, banks drained in seconds, an overnight digital Armageddon - if that nightmare doesn’t happen, some assume Q-Day wasn’t so bad after all. But this view misses a crucial point. The real catastrophe of Q-Day isn’t that everything will crash at once - it’s that our confidence in all things digital will collapse in an instant. In reality, when quantum code-breaking arrives, nothing visibly “breaks” on day one - websites still load, bank apps still work - yet one of the fundamental ...

Preparing a large telecom (or any enterprise) for the post-quantum cryptography era is a massive, multi-faceted undertaking, but it is achievable with foresight, resources, and commitment. We’ve seen that it involves much more than just installing new algorithms - it’s about transforming an organization’s approach to cryptography across potentially thousands of applications and devices, under uncertain timelines and in coordination with many external players. In all likelihood, this quantum-readiness program will be one of the most complex IT/security projects the organization has ever executed, comparable to - or even exceeding - major transformations like the rollout of a new network generation or a large merger integration. The program spans technology, ...

An arXiv review of enterprise readiness puts organizations with a formal quantum transition plan below 5%. The figure comes from ISACA's 2025 poll, and banks and telecoms are the only sectors budgeting at scale ...

The new performance analysis of Kyber and Dilithium is a welcome addition to the PQC literature. It confirms that post‑quantum security and good performance are not mutually exclusive, especially when using optimized implementations. In fact, Kyber and Dilithium often outperform classical cryptography at comparable security levels. This challenges the narrative that PQC will drastically slow down our networks. At the same time, the paper reinforces my earlier message: migration is not plug‑and‑play. Larger keys and messages can disrupt protocols and devices, and side‑channel security remains paramount. Enterprises must plan for interoperability, increased memory usage, and hardware support. Hybrid deployments, staged rollouts, and thorough testing are essential ...

Quantum Internet Alliance researchers published QNodeOS in Nature, running high-level quantum network programs on NV-centre nodes in Delft, adding a driver for a trapped-ion node in Innsbruck, and multitasking two applications ...

The race is on to quantum‑proof the world’s telecom networks. With cryptographically relevant quantum computers (CRQC) projected to arrive by the 2030s, global communications providers face an urgent mandate to upgrade their security foundations. Today’s mobile and fixed‑line networks rely on public-key cryptography that quantum algorithms could eventually break. In response, the telecom industry is turning to post-quantum cryptography (PQC) as the primary defense. Yet adopting PQC at telecom scale is a complex journey, entailing far more than a simple swap of algorithms. It demands strategic foresight and technical rigor to overcome unique architectural and operational hurdles. As an anecdotal example, my team has been working with one telecommunications provider ...
