4 terms

federated learning technical

"Federated learning uses a distributed training mechanism"

A method of building artificial intelligence where many devices or locations train the same model using their own private data and only share the model updates, not the raw data—like many cooks each stirring their own pot and sending a note about what worked. It matters to investors because it lets companies improve products and personalization while lowering data-transfer costs and privacy risk, affecting regulatory compliance, customer trust, and the scalability and competitive value of AI-based offerings.

quantum neural networks technical

"deeply integrating quantum neural networks (QNN) with classical"

Quantum neural networks are computing models that combine ideas from quantum mechanics with the structure of artificial neural networks to process information in fundamentally different ways than ordinary computers. For investors, they matter because the technology promises potentially much faster or more powerful machine learning for tasks like pattern recognition and optimization, but it also carries high technical uncertainty and long timelines, making related investments speculative and high-risk.

parameterized quantum circuits technical

"quantum neural networks composed of parameterized quantum circuits (PQC)"

Parameterized quantum circuits are programmable sequences of quantum operations with adjustable knobs (parameters) that you tune to make the circuit produce a desired output, similar to adjusting equalizer sliders to improve sound. Investors care because these circuits are the leading approach for running useful tasks—like pattern recognition, optimization and simulation—on current and near-term quantum hardware, so progress can signal commercial potential, partnerships, and value drivers in quantum-focused firms.

mini-batch gradient descent technical

"The output layer employs the mini-batch gradient descent algorithm"

A training method for machine learning models that updates model parameters using small, randomly selected groups of data called mini-batches instead of the entire dataset or single examples. This approach speeds up learning, reduces memory needs, and balances stable progress with some beneficial randomness, similar to testing a recipe in small batches rather than remaking the whole dish every time. Investors care because the choice of training method affects how quickly and reliably models for trading, forecasting, or risk scoring reach usable performance and how much computing cost and operational risk those models carry.

BEIJING, Aug. 4, 2026 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, is exploring a federated training framework for hybrid quantum-classical machine learning models, deeply integrating quantum neural networks (QNN) with classical pre-trained convolutional models, achieving dual breakthroughs in model accuracy and training efficiency through a distributed quantum computing architecture, and opening up innovative technical paths for data privacy protection and large-scale model training.

Quantum computers, through the superposition and entanglement states of qubits, can process an exponential number of computational tasks in parallel. This characteristic gives quantum machine learning (QML) potential advantages in tasks such as optimization problems and feature extraction. However, current quantum hardware is limited by factors such as noise and decoherence time, making it difficult to directly support the training of large-scale deep learning models. Federated learning uses a distributed training mechanism of "data stationary, model moving" to allow local nodes to share only model parameters to a central server for aggregation while retaining the original data. This mode effectively avoids the leakage risks brought by centralized data storage, but traditional FL frameworks still face two major challenges: first, the computational overhead of classical neural networks on edge devices leads to low training efficiency; second, the communication costs in the model parameter transmission process surge with the growth of node scale.

The fusion of quantum computing and federated learning provides solutions to the above problems. The parallel computing capability of quantum algorithms can reduce the complexity of optimization problems in high-dimensional feature spaces from exponential to polynomial levels, while the distributed architecture of federated learning provides a natural carrier for the engineering deployment of quantum models. The deeply collaborative hybrid architecture constructed by WiMi uses classical pre-trained convolutional models to handle underlying feature extraction tasks, leveraging their mature advantages in learning basic features such as image textures and edges, with quantum neural networks composed of parameterized quantum circuits (PQC) responsible for nonlinear mapping of higher-level abstract features, enhancing feature expression capabilities through quantum entanglement characteristics; ultimately, multi-node model collaborative optimization is achieved through the federated learning framework.

This innovative architecture demonstrates three major breakthroughs in its technical implementation. At the model design level, it adopts a hybrid quantum-classical convolutional neural network (SHQCNN) structure, where the input layer maps image data from low-dimensional space to high-dimensional quantum feature space through kernel encoding methods, solving the adaptation challenges between quantum states and classical data. The hidden layer innovatively introduces enhanced variational quantum circuits, which, through optimization of quantum gate combinations and adaptive parameter adjustment strategies, achieve feature extraction capabilities comparable to deep classical CNNs with only dozens of qubits, while avoiding the accumulation of quantum noise as circuit depth increases. The output layer employs the mini-batch gradient descent algorithm, accelerating model convergence through a high-frequency weight update mechanism, making the fusion decision of quantum-classical features more efficient. In the federated training mechanism, WiMi designs a layered aggregation communication protocol. Local nodes retain only the classical pre-trained convolutional base model and lightweight quantum processors; after completing local data feature encoding and model training through quantum circuits, only the encrypted quantum parameter gradients are uploaded to the central server, rather than raw feature data. The central node uses quantum state technology to complete cross-node parameter aggregation, then generates global update parameters through a classical optimizer and distributes them to each node.

The hybrid quantum-classical federated learning framework researched by WiMi marks a paradigm shift in machine learning from classical computing to quantum-enhanced computing, solving the core issues of data privacy and training efficiency. With the maturation of quantum hardware and optimization of algorithms, this innovative technology is expected to lead the transformation of next-generation artificial intelligence infrastructure.
