WiMi Hologram Cloud Integrates Quantum Circuits into Federated Learning

The architecture, dubbed SHQCNN, addresses the disparity between high-dimensional quantum potential and classical data constraints. By mapping image data into quantum feature space via kernel encoding, the system utilizes variational quantum circuits within the hidden layers. These circuits perform non-linear mapping of abstract features, matching the capabilities of deep classical networks while requiring only dozens of qubits. This design effectively mitigates the accumulation of quantum noise that typically plagues deeper circuit implementations.

To manage the training process, WiMi employs a layered aggregation protocol that prioritizes data privacy. Local nodes retain their raw datasets, transmitting only encrypted quantum parameter gradients to a central server. The server then executes cross-node aggregation using quantum state technology before distributing updated weights back to the network. This approach replaces the heavy computational overhead of traditional edge-device training with a lightweight model that balances local processing with global synchronization. As quantum hardware matures, this hybrid model offers a potential pathway for scaling artificial intelligence without compromising individual data sovereignty.
