Full Summary
Polarimetric materials, which reflect light in a way that depends on its polarization, present unique challenges for classification due to their complex data structures. A novel quantum-classical hybrid pipeline was developed to address this issue, framing the classification task as a point-matching problem.
The method involves training an encoder on voxel cubes—3D representations of polarized light reflections—to generate 32-dimensional embeddings. During inference, the encoder head is removed, and these embeddings are transformed into probability amplitudes of quantum states.
A SWAP-test circuit is then employed to estimate the fidelity, or similarity, between the embeddings from the query and the database. This approach significantly improves the efficiency and accuracy of material classification, demonstrating the potential of quantum computing in practical applications.
The findings suggest that integrating quantum techniques can enhance traditional machine learning methods in complex data scenarios.
