It has been a long journey in the making.
Our company began as a blockchain-focused venture with a clear mission: to protect blockchain systems against the emerging risks posed by quantum computing. While we have never abandoned that mission, our work on QSB (Quantum Secured Blockchain) led us to discover a much broader landscape of applications for our technology.
As a result, we expanded our focus beyond blockchain security and into the wider field of quantum and post-quantum cryptography. Along the way, we developed practical approaches that help organizations migrate to quantum-resistant security in a straightforward and cost-effective manner.
This evolution naturally called for a new identity.
We are therefore delighted to announce that, effective May 29, 2026, Quantum Blockchains has officially become Quantum B.
The new name reflects both our origins and our future: a company dedicated to making quantum-safe security accessible across digital infrastructure, identity systems, communications networks, financial services, and, of course, blockchain technologies.
Our headquarters remain in Lublin, with operations in Lublin and Łódź, Poland. What has changed is not our commitment, but the scope of our ambition.
The quantum era is approaching rapidly, and we are excited to help organizations navigate it with confidence.
Welcome to Quantum B. 🚀
