SEALSQ diversifies risks and builds platform for quantum technologies

Swiss company SEALSQ, which develops and markets semiconductor, PKI, and post-quantum security solutions, has published an update on its strategy for building a comprehensive quantum technology ecosystem, based on targeted investments and acquisitions in the quantum computing field. SEALSQ reports it is investing in a selected portfolio of promising quantum computing companies, thereby constructing a vertically integrated platform that links quantum-resistant security at the semiconductor level with future quantum computers. The strategy aims to position SEALSQ as one of the few publicly traded companies offering access to multiple qubit technologies while also possessing an established business in secure semiconductors and post-quantum security solutions. Rather than betting on a single quantum computer architecture, the company is investing in several complementary approaches to fault-tolerant quantum computing, which are to be linked with its proprietary QS7001 security chip, the QVault-TPM platform, and its post-quantum cryptography (PQC) portfolio. SEALSQ has already completed investments in four quantum computing companies pursuing different solid-state and analog approaches, and is additionally working on further stakes in the areas of photonic quantum computers, carbon-based qubits, and post-quantum software. Since the quantum computing industry has not yet settled on a dominant qubit technology, SEALSQ is deliberately pursuing diversification, holding stakes in technologies such as electron-on-helium, silicon spin, and analog quantum approaches, while also examining photonic and carbon-based platforms. According to SEALSQ, this multi-technology strategy is intended not only to reduce the risk of betting on the wrong technology but also to improve access to technical know-how, partnerships, and future commercialization opportunities. "We're not betting on a single horse—we're building the racetrack," said Carlos Moreira, Founder, Chairman and CEO of SEALSQ. "By investing in the leading qubit technologies and connecting them with our post-quantum semiconductors, we are creating a unique 'Root-to-Qubit' platform that only very few companies worldwide can offer
