Our Mission

We build quantum-resistant technologies for the infrastructures the world depends on every day, from power grids, gas and water networks, and industrial or robotic systems, to digital identity ecosystems and blockchain-based platforms. Our work is driven by a clear conviction: the last line of defense must begin before the threat fully materializes.

Founded in Poland in 2021, the company emerged from an original focus on blockchain security and has since evolved into a broader mission: accelerating the practical adoption of quantum cryptography and post-quantum security. That evolution reflects the reality of today's threat landscape. As quantum computing advances, the resilience of digital systems will increasingly depend on how early organizations prepare their cryptographic foundations for the future.

Since its inception, Quantum B has developed technologies that combine the key pillars of modern quantum-resilient security: emulation of Quantum Key Distribution, post-quantum cryptography (PQC), and quantum randomness. Our solutions include pQKD (QKD) emulators, and the Quantum Cryptography Migration System (QCMS), designed to help organizations move step by step toward quantum-safe security architectures.

In addition to our products, we provide implementation support, cryptographic migration expertise, and specialized knowledge that help organizations translate emerging quantum-security concepts into operational protection.

Headquartered in Lublin, with operations in Łódź, Quantum B brings together specialists in quantum information science, cryptography, and software engineering, working toward one goal: securing the systems that modern society cannot afford to lose.
