SEALSQ Corp signed a $5 million commercial agreement with silicon-based quantum computing firm Quobly.
Quobly will integrate SEALSQ’s post-quantum security technologies and semiconductor solutions into its next-generation quantum platforms. This deal marks the commercialization phase of a partnership that began with SEALSQ's investment in Quobly in November 2025.
The collaboration embeds cybersecurity directly into hardware to develop secure and scalable quantum computing infrastructure. SEALSQ will provide technologies including Cryo CMOS ASIC, secure semiconductor architectures, and hardware-based Root-of-Trust systems.
The agreement follows Quobly’s recent €115 million Series A financing. This positioning allows SEALSQ to address rising global demand for post-quantum cybersecurity.
