Quantum computers will need to be secured like any other critical infrastructure, and SEALSQ just turned that thesis into a signed commercial contract.
SEALSQ Corp (NASDAQ: LAES) develops secure semiconductors and post-quantum cryptography technology. On July 10, the company announced a $5 million commercial agreement with Quobly, under which Quobly will integrate SEALSQ's quantum-security technologies, secure semiconductor solutions and related engineering and integration services into its silicon-based quantum computing platform. The deal converts a strategic collaboration first announced in November 2025 into commercial deployment, as Quobly industrializes its Alloy line of quantum processors.
The partnership has fresh capital behind it: in June 2026, Quobly raised a 115 million euro Series A led by Bpifrance, STMicroelectronics and SEALSQ to accelerate industrialization of its quantum processors. The companies intend to build a security architecture in which quantum computing infrastructure is authenticated, protected and managed through hardware-based identities and post-quantum cryptography, an early stake in what could become a standard requirement as quantum systems commercialize. At $5 million, however, the agreement is modest, and revenue from quantum-security deployments may take years to become material. This is market commentary, not investment advice — small-cap technology stocks are highly speculative and you can lose your entire investment.
