LONDON, February 24, 2026 -- Arqit Quantum Inc. (“Arqit”), a global leader in quantum-safe encryption, today announced the availability of its encryption software pre-installed inside an Intel Trust Domain Extensions (Intel TDX) trusted execution environment (TEE) on Intel NetSec Accelerator Reference Design-based accelerator cards. The result is confidential compute: trusted workloads, trusted networks, and trusted agents, even in shared or hostile environments.

Intel TDX provides hardware‑enforced isolation of virtual machines (VMs) and containers to protect data during processing on 4th Gen Intel Xeon Scalable processor and onwards. Arqit’s software generates quantum‑safe encryption keys which are created on demand and consumed within the TEE created by Intel TDX, separating workloads in multi-tenant environments and from cloud operators. The keys are never stored or exchanged, and Arqit’s cryptography provides security now and against future threats, even a quantum computer. Every data packet can now be protected with quantum-safe keys by default, at line speed, utilising hardware-accelerated technology, from cloud to edge.

Enabling new high-growth security services for telecom operators and critical national infrastructure

This development supports a wide range of telecom and critical communications infrastructure use cases, allowing service providers to deploy advanced security capabilities for existing and new offerings, including:

• Data sovereignty regardless of cloud or AI provider geography
• Quantum-safe data in transit and in process
• Secure Network-as-a-Service (NaaS)
• High-speed quantum safe IPSec VPNs without latency

By embracing these capabilities, Telcos can differentiate their services and build new revenue streams while meeting the rising demand for post-quantum security and protecting ever more valuable digital assets by confidential computing across connected industries.

“Your data already outlives your cryptography”, said Scott Alexander, Chief Product Officer at Arqit. “Regulators and customers expect crypto agility today; quantum-safe trust across confidential compute and edge networks is how you secure and future-proof your data and communications.”

“Intel's market-leading security, built directly into our processors, provides the foundation for quantum-safe encryption in Arqit's solutions. Together, we are helping to establish unbreachable security as the standard for telco, government, and enterprise deployments,” said Cristina Rodriguez, VP and General Manager of Intel Network & Edge Group.

Arqit and Intel will demonstrate this technology at MWC Barcelona 2026, replicating a customer’s on-prem environment and showcasing a cost-effective, efficient, and scalable confidential compute solution. Network security is no longer “fast encryption” – it is “fast and quantum-safe encryption”, reducing business risk.
