What is a quantum-secure microcontroller unit (MCU)?

A post-quantum security chip is a hardware component designed to protect digital systems against cryptographic threats that could emerge with the development of large-scale quantum computers.

Traditional encryption algorithms widely used today—such as RSA and elliptic curve cryptography—may become vulnerable to quantum attacks. Post-quantum security chips address this challenge by integrating quantum-resistant cryptographic capabilities and hardware-based protection mechanisms directly into semiconductor architectures.

By embedding security at the hardware level, it helps ensure long-term protection for connected devices, infrastructure and digital ecosystems operating in an increasingly complex cybersecurity landscape.

Solutions such as the Quantum Shield QS7001 enable organizations to prepare their systems for the transition toward quantum-resilient cybersecurity while maintaining strong protection against today’s cyber threats.
