SEALSQ Corp (NASDAQ: LAES) announced strategic investments and acquisitions across multiple quantum computing companies to establish what the company calls a "Root-to-Qubit" platform. The semiconductor and post-quantum technology company disclosed investments in four quantum computing firms: EeroQ, Quobly, Miraex, and an undisclosed fourth company.

The Geneva-based company said it is pursuing a multi-modality approach across different quantum technologies, including electron-on-helium, silicon spin, and analog approaches. SEALSQ indicated it has additional investments planned across photonics, carbon-based qubits, and post-quantum software platforms.

The investment strategy aims to connect SEALSQ's existing post-quantum cryptography business with emerging quantum computing hardware. The company currently produces the QS7001 secure element and other post-quantum semiconductor products that generate revenue.

"SEALSQ has built his foundation at the Root of Trust, securing the digital infrastructure that the world depends on," said Carlos Moreira, founder, chairman and CEO. "Moving into the full quantum stack is the natural extension of that mission."

SEALSQ's quantum portfolio spans companies working on different qubit technologies rather than focusing on a single approach. The company stated this diversification strategy aims to reduce architectural risk as the quantum computing industry has not converged on a dominant technology.

The company plans to continue evaluating quantum investments and partnerships through 2026, with the goal of integrating quantum-resistant security with quantum computing access in commercial offerings. SEALSQ indicated it will disclose additional transaction details as appropriate and in accordance with securities regulations.
