Implement a quantum secure multiparty computation use case.
The use case demonstrates a quantum secure multiparty computation of phylogenetic trees, involving three private genome databases placed at three distinct nodes in the Madrid quantum network: UPM (CCS) – Node A, CIEMAT - Node C, and RM-CSIC – Node B. Such SMC service will enable distributed parties in a network to jointly compute arbitrary genome analysis without revealing their private genome sequences. In the use case, the three Nodes will run a quantum-enabled SMC procedure to jointly compute the matrix distance of the genome sequences present in the private databases. For that purpose, the different Node pairs (e.g., Node A – Node C; Node A – Node B; and Node B – Node C) will consume oblivious keys to compute the matrix distance entries corresponding to the genome sequences belonging to different databases. Such oblivious keys will be generated through the implemented QODK protocol that, in turn, will be supported by the Huawei continuous-variable Quantum Raw Key Distribution (CV-QRKD) link. After computation of the matrix distance entries corresponding to the sequences from the same database, the three Nodes will share the missing matrix distance entries via encrypted messages (AES), whose cryptography keys result from an XOR operation of two previously generated keys via Huawei’s CV-QKD and IDQ’s DV-QKD links. Once obtained the full matrix distance, the three nodes can iteratively group the genes with the fewest differences between them. The final output, shared by the three Nodes, will be the phylogenetic tree corresponding to the genome sequences belonging to the three private genome databases.
