- Arqit partners with telcos including Vodafone, Sparkle and Intel to deliver quantum-safe encryption solutions ahead of “Q-Day”.
- The startup offers symmetric-key platforms that protect networks, SD-WANs and undersea cables against future quantum risks.
What happened: Arqit leads charge for telecoms’ quantum-safe security
Arqit, founded over five years ago, is working closely with carriers and enterprises to prepare networks against the looming threat of quantum computer attacks (“Q-Day”). Capacity Media reports that Andy Leaver (CEO) and Dr Daniel Shiu (chief cryptographer) explain how public-key encryption’s vulnerabilities are now a pressing concern for telcos.
The company has executed proof-of-concepts with Italian telecommunications firm Sparkle. It is also partnering with Vodafone via its Tomorrow Street innovation hub, offering quantum-safe solutions to Vodafone’s enterprise customer base.
Arqit’s technology includes a symmetric key encryption platform described by Leaver as “the gold standard” for securing diverse environments—from air-gapped systems to cloud and SD-WAN. It integrates with Intel’s platforms, including Xeon processors, and works towards ensuring secure, high-performance IPsec resistant to quantum attacks.

Why it’s important
Telecommunications increasingly underpin critical infrastructure: data centres, undersea cables, cloud services and financial systems all depend on encryption. With quantum computing advancing, the risk that adversaries could record encrypted data now and decrypt it later (the “store-now-decrypt-later” threat) becomes significant. Arqit’s work addresses these risks proactively.
By aligning with trusted industry players like Intel and Vodafone, Arqit strengthens confidence in deployment. These collaborations allow for real-world testing and adoption among large enterprises and telcos that demand reliable security across multiple jurisdictions. The symmetric-key model, which Arqit promotes, offers simpler key management and potentially fewer attack vectors compared to more complex public-key systems.
From a positive stance, this initiative is both timely and necessary. Waiting until quantum becomes mainstream would expose networks to retrospective breaches. Early action, as Arqit is taking, helps future-proof infrastructure, protects user data, and preserves trust. Regulatory alignment on encryption standards and international cooperation will remain critical. As many countries debate quantum encryption norms, Arqit’s flexible, hardware-agnostic solution could serve as a template. Telecommunication providers risk falling behind unless they adopt quantum-safe protocols now; Arqit’s leadership suggests that some are already stepping up.
