Quantum computing has long promised to solve problems that classical computers cannot — but turning that promise into reality depends heavily on one unglamorous foundation: semiconductors.
SEALSQ, a company focused on secure semiconductors and post-quantum technologies, is drawing attention to the critical role the chip industry must play if quantum computing is ever to scale beyond laboratory demonstrations. According to coverage in Electronics For You Business, SEALSQ is emphasizing that advances in semiconductor fabrication, packaging, and integration are not just supporting infrastructure for quantum systems — they are central to making those systems work at meaningful scale.
The argument is straightforward: quantum processors require extraordinarily precise physical environments and control systems that themselves rely on conventional semiconductor components. Without continued progress in chip design and manufacturing, quantum hardware cannot be miniaturized, stabilized, or made cost-effective enough for commercial deployment.
SEALSQ's positioning here is notable because the company sits at the intersection of two converging trends — the push toward quantum-resistant cryptography and the broader hardware race to enable quantum machines. Highlighting the semiconductor dependency underscores that quantum computing's timeline is not just a software or algorithm problem; it is a manufacturing and materials challenge as much as anything else.
Why it matters: if the semiconductor industry does not deliberately orient part of its roadmap toward quantum computing needs, the much-hyped quantum revolution could remain perpetually out of reach — making chipmakers, not just quantum startups, the real gatekeepers of the technology's future.
