SEALSQ and Quobly Execute $5M Commercial Accord to Embed Post-Quantum Cryptography in Silicon Quantum Processors

Post-quantum semiconductor developer SEALSQ Corp (NASDAQ: LAES) has signed a $5 million commercial agreement with French silicon-based quantum hardware pioneer Quobly. The contract signals the deployment phase of a technology partnership initiated in November 2025 following SEALSQ’s direct equity investment in the firm. The contract tracks Quobly’s massive €115 million Series A capitalization round completed in June 2026, funding the industrialization of its Fully Depleted Silicon-On-Insulator (FD-SOI) quantum processor architecture. Under the terms of the transaction, SEALSQ will provide a specialized portfolio of quantum-resistant hardware cores, cryptographic modules, and security architecture engineering services to harden Quobly’s multi-vendor cloud and data center platforms against future decryption threats.
