Hybrid quantum-neural network beats classical machine learning

Researchers at the Institute of Fundamental and Frontier Sciences, University of Electronic Sciences and Technology of China have combined boson sampling, a quantum process with experimentally verified advantage over classical computers, with neural networks to improve machine learning classification. The team developed a hybrid framework where a neural network compresses data features onto a boson sampling circuit, generating quantum states that enhance support vector machine performance. Using four datasets with various classes, the model outperformed classical linear and sigmoid kernels, demonstrating the potential of boson sampling-based quantum kernels for practical quantum-enhanced machine learning. The core innovation lies in…
