To provide scalable, secure Silicon Based Quantum Computing, SEALSQ announces a strategic shift towards CMOS-compatible quantum computing architectures.
Overview
The content describes SEALSQ Corp.’s strategic push into creating quantum computer architectures that work with current semiconductor fabrication techniques. Using silicon spin qubits and electron-on-helium platforms, the business hopes to develop scalable systems that leverage well-established CMOS technology to simplify production. This strategy places a high priority on security by design, including hardware-based trust and post-quantum cryptography built directly into the chip architecture to ward off cyberattacks.
The business emphasizes that by enabling the co-integration of quantum devices with classical control circuitry, silicon-based systems offer a notable advantage over alternative quantum approaches. In the end, these developments aim to offer sensitive data protection that is future-proof across a variety of industries, such as industrial automation, healthcare, and defense.

The Silicon Way to Scalability
The choice of qubit technologies that organically integrate into the global semiconductor ecosystem is the basis of SEALSQ’s approach. The business is focusing on two main strategies: electrons-on-helium platforms and silicon spin qubits. Utilizing silicon’s electrons, silicon spin qubits are produced using techniques comparable to those used to create conventional CMOS chips, which could greatly facilitate large-scale production. On a silicon chip, electrons are positioned above superfluid helium in the electrons-on-helium technique. This technique provides a low-noise substitute for quantum processing while enabling the use of CMOS-compatible controllers.
CMOS compatibility is viewed as a “system-level enabler” rather than just a manufacturing preference. In addition to qubits, the development of a functioning quantum processor involves electronics that can perform at cryogenic temperatures, large arrays of control electrodes, and high-speed signal routing. A viable framework for the co-design and ultimate co-integration of these quantum devices with traditional CMOS control circuitry is offered by silicon-based platforms. SEALSQ is turning to FDSOI (Fully Depleted Silicon-On-Insulator) technology, a wafer-level semiconductor process that uses a thin silicon layer on an insulating layer to maximize performance in these challenging settings, to address the issues of noise and power consumption.
An Advantage Compared to Specialized Systems
The benefits of this alignment over other well-known quantum techniques were emphasized by Carlos Moreira, the founder and CEO of SEALSQ. Although superconducting or ion-trap systems are interesting from a technical standpoint, he pointed out that they sometimes need specialist materials and intricate vacuum or optical settings that are difficult to integrate into common production.
On the other hand, Moreira said, “electron-on-helium and silicon spin qubits are designed from the beginning to evolve within the semiconductor ecosystem.” He went on to say that this alignment places SEALSQ in the special nexus of safe, large-scale manufacturing and quantum innovation, speeding up learning cycles and guaranteeing a seamless transfer from research to production.

Security-by-Design and Post-Quantum Cryptography
The direct integration of hardware-based trust mechanisms and Post-Quantum Cryptography (PQC) into the system architecture is a unique aspect of SEALSQ’s roadmap. The business contends that security should not be an afterthought but rather a fundamental necessity as quantum computers develop.
Traditional cryptography techniques like RSA and Elliptic Curve Cryptography (ECC) are getting harder to crack as quantum computer power increases. The “Quantum Threat” is being addressed by SEALSQ by the integration of PQC algorithms into secure silicon. This guarantees that calibration data, firmware upgrades, and quantum control systems are protected from both traditional and quantum-enabled assaults. For distributed quantum systems, where sensitive data must be sent between control electronics and cloud-connected layers, this degree of security is very important.
Additionally, trusted boot, device attestation, and secure key storage will be made possible by secure components manufactured in conjunction with quantum circuitry. As these devices go from laboratories to networked, mission-critical infrastructure, these characteristics guarantee that only authorized operators and verified software may access or alter sensitive quantum systems.

Promoting Innovation in International Sectors
The emphasis SEALSQ places on scalable, secure semiconductors has wide-ranging effects on several industries. The business is at the forefront of post-quantum semiconductors, which are intended to secure sensitive data in a variety of applications in the future, such as:
- Industrial automation and smart energy: safeguarding power grids and control systems.
- Automotive: Protecting vehicle communications and EV charging infrastructure.
- Healthcare & Medical: Preserving the accuracy of medical systems and private patient data.
- Defense and IT Infrastructure: Protecting international network communications and national security resources.
- Luxury goods and consumer IoT: offering trademark protection and anti-counterfeiting measures.
SEALSQ seeks to address a major issue of the contemporary period by fusing embedded security with CMOS-based quantum hardware: making sure that the very devices intended to crack today’s encryption are safe and independent by design. Silicon-based quantum computing is positioned as a practical, safe alternative for government and critical infrastructure settings due to the confluence of quantum physics with semiconductor engineering.
