Quantum B Secures European Patent for Quantum Conference Key Agreement Protocol

Quantum B has been granted European Patent EP 4462727 for its Quantum Conference Key Agreement (QCKA) protocol. This protocol utilizes multipartite quantum entanglement to establish distributed consensus across independent network nodes, offering an alternative to classical consensus mechanisms. The technology aims to lower communication overhead for multi-party synchronization and is part of Quantum B’s broader portfolio, including its involvement in the EU-funded POSEIDON project.
