Vision-brain understanding aims to extract semantic information about brain signals from human perceptions. Existing deep learning methods for vision-brain understanding are usually introduced in a traditional learning paradigm missing the ability to learn the connectivities between brain regions. Meanwhile, the quantum computing theory offers a new paradigm for designing deep learning models. Motivated by the connectivities in the brain signals and the entanglement properties in quantum computing, we propose a novel Quantum-Brain approach, a quantum-inspired neural network, to tackle the vision-brain understanding problem. To compute the connectivity between areas in brain signals, we introduce a new Quantum-Inspired Voxel-Controlling module to learn the impact of a brain voxel on others represented in the Hilbert space. To effectively learn connectivity, a novel Phase-Shifting module is presented to calibrate the value of the brain signals. Finally, we introduce a new Measurement-like Projection module to present the connectivity information from the Hilbert space into the feature space. The proposed approach can learn to find the connectivities between fMRI voxels and enhance the semantic information obtained from human perceptions. Our experimental results on the Natural Scene Dataset benchmarks illustrate the effectiveness of the proposed method with Top-1 accuracies of 95.1% and 95.6% on image and brain retrieval tasks and an Inception score of 95.3% on fMRI-to-image reconstruction task. Our proposed quantum-inspired network brings a potential paradigm to solving the vision-brain problems via the quantum computing theory.

Brain tumor detection is a vital and challenging task in medical diagnosis, requiring highly precise and efficient methods to improve patient treatment outcomes. Traditional approaches rely on classical machine learning and deep learning techniques, which, while effective to a degree, often struggle with capturing the complex and high-dimensional patterns present in medical imaging data.

Modeling brain-wide functional connectivity remains one of the central challenges in computational neuroscience due to the enormous dimensionality, nonlinearity, and dynamical complexity of neural interactions. Classical network models, while effective for localized circuits, struggle to capture long-range dependencies, cross-frequency coupling, and emergent global patterns across billions of neurons and trillions of synapses. Quantum computational approaches offer a promising new direction by exploiting superposition, entanglement, and high-dimensional quantum state representations to encode whole-brain connectivity more efficiently. This study proposes a quantum-enhanced framework for modeling large-scale functional connectivity using hybrid quantum–classical graph algorithms, variational quantum neural models, and quantum kernel-based similarity mapping. By encoding temporal neural signals into quantum states and performing state-space exploration with variational circuits, the framework aims to reveal latent connectivity patterns, global synchronization structures, and cross-network dynamics that classical methods often fail to identify. Early simulation results suggest improved sensitivity to weak long-range interactions and enhanced ability to detect dynamic functional modules. The proposed approach highlights the transformative potential of quantum computation in advancing systems-level neuroscience, enabling more accurate whole-brain models and opening new opportunities for understanding cognition and neurological disorders.

Quantum-inspired architectures are inspired by quantum mechanics, superposition, entanglement as well as interference to redesign visual information processing in a more efficient way. Quantum convolutional neural networks are one of the biggest improvements as they apply parameterized quantum circuits to explore several input states at a time. Quantum-inspired pruning algorithms have lowered the processing time, and quantum optical neural networks have used the wave nature of light to have parallel characteristics of features.

Attention systems ensure that quantum circuits are dedicated to informative parts of an image, whereas knowledge transfer of classical models stabilizes quantum training. Nonetheless, basic constraints limit applications: the barren plateau problem, measurement overhead, preparation complexity of states and decoherence are all major challenges. The existing applications include quantum-inspired classical algorithms to physical hardware experiments. Thorough benchmarking demonstrates that the classical approaches can be much more effective than the quantum ones. Frameworks such as PennyLane extend accessibility, although best practice and careful consideration of the architecture involving the integration of quantum-inspired and classical computing is critical to realistic computer vision systems.
