Handwritten digit recognition in regional scripts, like Devanagari, is essential for various purposes.
Conventional models face challenges due to the script's complexity and limited annotated datasets.
This paper presents a hybrid quantum-classical architecture for Devanagari handwritten digit recognition.
The architecture combines a 10-qubit variational quantum circuit (VQC) with a convolutional neural network (CNN) for spatial feature extraction.
The model achieves a quantum test accuracy of 99.80% and a test loss of 0.2893 on the Devanagari Handwritten Character Dataset.
The average per-class F1-score achieved by the model is 0.9980.
Compared to classical CNNs, the proposed model demonstrates better accuracy with fewer parameters and improved robustness.
By utilizing quantum principles like superposition and entanglement, this work sets a new standard for regional script recognition.
The research highlights the potential of quantum machine learning (QML) in low-resource language settings.
The model's performance showcases promising implications for multilingual document digitization, educational tools, and cultural heritage preservation.
