WISeKey Worldwide’s subsidiary SEALSQ and Quobly have agreed to discontinue talks regarding a possible majority funding or acquisition of Quobly by SEALSQ.
Each firms introduced the choice, stating they may as a substitute contemplate a minority funding possibility. This prospect can be revisited as soon as Quobly launches its Collection A financing spherical.
Entry deeper business intelligence
Expertise unmatched readability with a single platform that mixes distinctive knowledge, AI, and human experience.
The transfer follows a joint evaluation {that a} minority funding aligns extra intently with present traits in quantum computing funding in France.
SEALSQ develops and sells semiconductors, PKI, and post-quantum know-how {hardware} and software program merchandise. Quobly specialises in silicon-based quantum microelectronics.
Regardless of ending discussions on a majority funding or acquisition, the 2 companies intend to proceed their technical and industrial collaboration that started in November 2025.
Their ongoing partnership focuses on the intersection of safe semiconductor applied sciences and scalable quantum architectures.
As a part of their collaboration introduced in November 2025, SEALSQ and Quobly are working collectively to merge safe semiconductor architectures with scalable quantum methods.
The partnership leverages SEALSQ’s experience in post-quantum safety options alongside Quobly’s silicon-based quantum processor know-how.
Each events purpose to discover how superior safety {hardware} can combine with quantum processing for future industrial functions.
Quobly’s know-how contains absolutely silicon-based quantum processors designed for compatibility with customary CMOS manufacturing processes.
Its method includes using cryogenic management electronics and scalable interconnects for multi-qubit methods, key elements supposed to assist fault-tolerant quantum computing at an industrial scale.
SEALSQ offers post-quantum semiconductors, safe parts, TPM (Trusted Platform Module) chips, and Root-of-Belief applied sciences for vital infrastructure safety worldwide.
Its choices embody post-quantum cryptographic algorithms optimised for embedded gadgets, safe semiconductor personalisation providers, and safe communication stacks appropriate for IoT networks, automotive functions, satellite tv for pc methods, and different vital environments.
Each firms have acknowledged that their collaboration goals to make sure safety necessities are addressed as large-scale quantum computing strikes nearer to industrial use.
They plan to look at strategies for integrating quantum-resistant safety measures from the earliest design levels of latest methods.
Final month, SEALSQ and Kaynes SemiCon signed a binding settlement to ascertain a three way partnership known as SEALKAYNESQ, which can be based mostly in India.
