Key Contributions:

  • Proposes a hybrid ML framework combining a classical deep network and a variational quantum circuit (VQC) on a single qudit to classify time-series data.
  • Utilizes a trainable autoencoder embedding to map classical data into the quantum circuit’s space efficiently.
  • Demonstrates that classification performance can be maintained, while drastically reducing the number of trainable parameters—a path toward resource-efficient quantum-augmented learning.
  • Highlights how tailored preprocessing and embedding strategies are crucial for maximizing the benefit of hybrid quantum-classical architectures.

This work aligns with the Allegro EU Project’s mission to explore quantum-enhanced data processing methods in communication and network contexts.
