SEALSQ Corp announced on April 16, 2026 that it will launch its new Quantum Vertical Stack, a fully integrated ecosystem that spans silicon‑level root of trust, post‑quantum cryptography, quantum interconnects, quantum sensing, and space‑based quantum infrastructure. The company said the stack will be unveiled during its SEALSQ Quantum Day in the third quarter of 2026, marking the first time it will present a fully integrated quantum solution to the market.
The launch represents a significant milestone for SEALSQ, positioning it as a potential first‑mover in the emerging quantum‑ready semiconductor market and expanding its product portfolio beyond legacy secure elements. By embedding post‑quantum security directly into its chips and coupling that with a sovereign quantum highway, SEALSQ aims to provide a seamless, secure platform for customers in defense, critical infrastructure, and high‑value data centers.
CEO Carlos Moreira said, "At SEALSQ, we are not just preparing for the quantum era, we are engineering it vertically, securely, and at scale." He added, "We are building a quantum vertical stack that integrates every critical layer of trust, from quantum‑ready hardware and post‑quantum cryptography to secure operating systems, edge and IoT integration, and resilient satellite infrastructure. By embedding quantum‑resistant technologies directly into chips, devices, and communications networks, SEALSQ ensures that security is not an afterthought but a foundational principle." Moreira also noted, "While quantum technologies will evolve rapidly, trust, identity, and sovereignty remain stable across decades of innovation. By anchoring these principles in hardware and scaling them globally via the Quantum Highway, SEALSQ aims to build a durable trust infrastructure for governments, critical infrastructure operators, and regulated industries seeking secure, sovereign, and resilient post‑quantum and quantum solutions."
The announcement comes amid accelerating regulatory mandates for post‑quantum cryptography, such as NIST standards and the EU Cyber Resilience Act, and growing demand from defense and critical infrastructure sectors. SEALSQ’s comprehensive stack is expected to open new revenue streams as these mandates take effect, reinforcing the company’s competitive moat.
The launch marks a significant milestone for SEALSQ, underscoring its commitment to leading the quantum technology transition and positioning it to capture emerging opportunities in secure, quantum‑ready hardware and services.
