BEIJING, Aug. 21, 2026 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WiMi) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, proposes a cutting-edge quantum machine learning technology oriented toward classical data classification tasks—a quantum convolutional neural network with interaction layers for classical data classification. This technology systematically enhances the overall performance of quantum convolutional neural networks in terms of expressive power, entanglement generation capability, and actual classification performance by introducing a novel interaction layer structure based on three-qubit interactions, marking an important step forward in the structural design of quantum deep learning models toward a new phase driven by multi-body interactions.
From the perspective of technical implementation logic, this quantum convolutional network adopts an overall hybrid quantum-classical architecture design. First, classical data is mapped to the quantum state space through an efficient data encoding strategy, ensuring that as much discriminative information from the original data as possible is preserved under limited qubit resources. For image data, the network employs block partitioning and local mapping approaches to embed pixel information into corresponding quantum subsystems; for one-dimensional data, a combination of structured amplitude encoding and angle encoding is used to achieve a compact representation of data features. After data encoding is completed, the quantum state is fed into the quantum feature extraction module composed of multiple layers of quantum convolutional units and interaction layers.
In this module, quantum convolution operations and the novel interaction layers are executed alternately. The quantum convolutional layers are responsible for extracting low-order features within local qubit subspaces, with their structural design adhering to hardware-friendly principles to avoid introducing excessively deep or difficult-to-implement quantum gate sequences. The interaction layers serve as the key innovation of the entire network, achieving cross-channel and cross-scale information fusion through three-qubit interactions. This design enables the network to significantly enhance its expressive power for complex patterns while keeping circuit depth under control. The WiMi R&D team systematically studied the impact of this interaction layer on the coverage capability of the quantum state space in theoretical analysis. The results show that after introducing three-body interactions, the set of reachable states in the parameter space of the network is significantly expanded, effectively alleviating the common expressivity limitation problem in traditional quantum neural networks.
In terms of entanglement capability, WiMi further conducted an in-depth analysis of the proposed network structure from the perspective of quantum information theory. The study shows that the three-qubit interaction layer can generate high-intensity, multi-scale entanglement structures at relatively shallow circuit depths, which is crucial for quantum machine learning models to capture nonlinear correlations in the input data. Compared to network structures that rely solely on two-qubit entanglement gates, the new model exhibits clear advantages across multiple metrics, including entanglement entropy, uniformity of entanglement distribution, and efficiency of entanglement propagation. This characteristic not only enhances the model’s learning capability but also provides strong support for maintaining stable performance under the presence of noise.
In terms of the training mechanism, this quantum convolutional neural network employs a joint iterative approach between classical optimizers and quantum circuit parameters to complete model learning. The output of the quantum circuit is mapped into classical feature vectors through measurement, which are then evaluated by a classical loss function to provide gradient feedback. Addressing the common issues of gradient vanishing and optimization instability in quantum model training, WiMi systematically optimized the parameter initialization strategy and training procedure, enabling the model to achieve stable convergence in both multi-class and binary classification tasks. These engineering improvements ensure that the technology possesses advantages not only at the theoretical level but also has practical deployability and feasibility.
This achievement not only demonstrates the real-world potential of quantum machine learning in the field of classical data processing, but also provides a replicable and scalable technical paradigm for the architectural design of next-generation quantum intelligent systems. By systematically introducing multi-body quantum interactions into the structural design of neural networks, WiMi is driving the evolution of quantum algorithms from quantum acceleration tools toward quantum-native intelligent models. This direction is expected to form a synergistic effect with the future development of quantum computing hardware, unleashing even more disruptive computational capabilities.
WiMi plans to further expand the model scale and application scenarios on the basis of existing technology, including directions such as higher-dimensional image data, complex time series analysis, and cross-modal data fusion. At the same time, it will continue to focus on noise robustness and hardware adaptability issues, promoting the verification and deployment of this quantum convolutional neural network on real quantum devices.
The technical achievement released by WiMi marks a substantial step forward in quantum machine learning model design, moving from imitating classical structures toward fully leveraging the intrinsic advantages of quantum physics. By deeply integrating multi-qubit interaction mechanisms at the network structure level, this technology provides solid support for performance breakthroughs of quantum convolutional neural networks in practical applications, and injects new momentum into the industrial development of quantum artificial intelligence.
