Overview

SEALSQ and Quobly have signed a $5 million commercial agreement aimed at the commercial deployment of post-quantum security solutions for quantum computing. Under this deal, Quobly will integrate SEALSQ’s secure semiconductor and hardware-based Root-of-Trust technology into its silicon-based quantum computing platform, which recently secured €115 million in Series A funding. This initiative addresses the growing imperative to protect quantum processors, control electronics, and communication networks against future quantum attacks.

In Depth

Key Findings

SEALSQ and Quobly have formalized a $5 million commercial agreement for the commercial deployment of post-quantum security solutions tailored for quantum computing systems. This partnership is designed to protect critical quantum infrastructure against potential future quantum-based attacks.

Technical / Clinical Details

Under the terms of the agreement, Quobly will integrate SEALSQ’s secure semiconductor and hardware-based Root-of-Trust technology into its silicon-based quantum computing platform. SEALSQ’s Root-of-Trust technology provides foundational security functions, ensuring the authenticity and integrity of devices during startup and data exchange. Quobly, having recently completed a €115 million Series A funding round, will use this technological integration to enhance security across its quantum processors, control electronics, and quantum communication networks. Specifically, this involves the hardware-level implementation of post-quantum cryptography (PQC) algorithms, enabling secure encrypted communication and data protection even against attacks from quantum computers.

Background & Context

As quantum computing capabilities advance, there is a growing concern that current public-key cryptographic systems could be broken, posing severe security risks to existing digital infrastructures. To counter this ‘quantum threat,’ the urgent development and deployment of new, quantum-resistant cryptographic techniques, known as Post-Quantum Cryptography (PQC), are imperative. Crucially, as quantum computing itself is still developing, securing its own infrastructure from quantum attacks is equally important. This partnership demonstrates an advanced approach to establishing quantum computing security, emphasizing that PQC is not merely a software update but requires deep hardware-level integration.

Strategic Significance & Outlook

The collaboration between SEALSQ and Quobly is poised to play a significant role in establishing security standards for the quantum era. Both companies aim to accelerate the adoption of PQC in a wide range of application areas demanding high security, such as data centers, cloud services, and IoT devices. The $5 million contract reflects strong market demand for robust security measures in quantum technology, and it is anticipated that many companies will adopt similar hardware-based PQC solutions going forward. This initiative will build a reliable foundation for the safe development and practical application of quantum technology.
