Arqit Quantum Inc News
Arqit Quantum Inc. and Intel Corporation announced a significant partnership to offer quantum-safe encryption pre-installed on accelerator cards based on the Intel NetSec Accelerator Reference Design, marking a paradigm leap for worldwide cybersecurity. Through the creation of a trusted execution environment (TEE) using Intel Trust Domain Extensions (Intel TDX), this integration guarantees that data is safeguarded both during active processing and while it is in transit.
The Looming Quantum Threat
The relationship is crucial as the “Harvest Now, Decrypt Later” (HNDL) danger rises. Adversaries are stealing encrypted data to decrypt it when Cryptographically Relevant Quantum Computers (CRQCs) are produced. A 20-million-qubit fault-tolerant quantum computer could crack a 2048-bit RSA key in eight hours, compared to one billion years for classical computers.
Due to the enormous difference in processing power, public-key encryption used today might be quickly made outdated, revealing everything from vital corporate assets to national secrets. With artificial intelligence (AI) and generative AI (GenAI) becoming more and more integrated into daily operations, there is an increasing need for security measures that can survive these future developments.

A Synergy of Hardware and Software
Intel’s hardware-based security technology and Arqit’s lightweight software agent work in concert to form the new solution’s core. Featured in Intel Xeon Scalable CPUs and later, Intel TDX offers hardware-enforced isolation for containers and virtual machines (VMs). This encrypts data as it is being used, separating workloads from the underlying infrastructure as well as the hypervisor and system administrators.
Setting up symmetric encryption keys between endpoints is another way that Arqit’s Symmetric Key Agreement (SKA) Platform enhances this. In contrast to conventional asymmetric keys, these quantum-safe keys are generated dynamically and used directly in the Intel TDX-created TEE. “By combining Intel TDX with Arqit’s quantum-safe encryption, we’re giving customers full control of their security, removing infrastructure providers from the trust equation entirely,” said Andy Leaver, CEO of Arqit Quantum Inc. The solution protects against man-in-the-middle attacks and HNDL spoofing because the keys are never stored or exchanged over the network.
Securing the AI and Telco Frontiers
Several high-growth industries are the focus of the partnership, most notably telecommunications and artificial intelligence. Companies creating AI solutions can be sure that the integrated technology provides end-to-end protection, protecting critical training data and proprietary models while they are in use. Both preserving competitive advantage and adhering to regulations depend on this.
Service providers can now provide new, high-growth security services in the telecom industry with the development. Among the important uses are
- Secure Network-as-a-Service (NaaS): The Secure Network-as-a-Service (NaaS) offers its global clientele high-end, quantum-safe connection.
- High-Speed VPNs: Offering IPSec VPNs that are quantum-safe without the latency problems that come with more complex encryption.
- Data Sovereignty: Regardless of the cloud or AI provider’s geographic location, data sovereignty enables governments and enterprises to maintain data inside their borders and safe from outside threats.
Intel’s market-leading security serves as the basis for this standard of “unbreachable security” across telco, government, and business installations, according to Cristina Rodriguez, VP and General Manager of Intel Network & Edge Group.

Digital Sovereignty and Rapid Deployment
The simplicity of implementation is among this collaboration’s most important benefits. The Intel TDX’s “lift and shift” architecture allowed Arqit and Intel to successfully produce a functional proof of concept in less than two weeks. This enables the quick transfer of private virtual machines (VMs) into extremely secure settings without necessitating a complete redesign of current infrastructure.
The solution is perfect for sensitive public sector applications and sovereign clouds for governments. By guaranteeing that data is encrypted while being processed, it lowers the possibility of exposure to other users or infrastructure owners in multi-tenant settings. Authorities and consumers now anticipate “crypto agility” to protect data from changing threats, according to Scott Alexander, Chief Product Officer at Arqit.
MWC Barcelona 2026
Starting March 2, 2026, MWC Barcelona 2026 will showcase this technology to the industry. Arqit and Intel will replicate a customer’s on-premises setup to demonstrate a cost-effective, scalable confidential compute solution. Network security is now about “fast encryption,” but it’s also about “fast and quantum-safe encryption,” as this demonstration seeks to demonstrate.
As part of its ongoing aim to “Detect, Protect, and Comply,” Arqit’s integration with Intel technology represents a significant turning point in the post-quantum age, guaranteeing the security of the most important data in the world both now and in the future.
