Researchers from Technical University of Munich, BMW Group, and Leiden University demonstrated the first successful encoding and classification of the complete Fashion-MNIST dataset on a real quantum computer, which was facilitated by a new resource-efficient sparse ansatz for data preparation.

Key insights

  • The proposed sparse ansatz achieves comparable approximation fidelities to previous approaches with significantly fewer CNOT gates (50% reduction) and shallower circuit depth (66% reduction).
  • Circuit complexity, particularly CNOT gate count, inversely correlates with performance on Noisy Intermediate-Scale Quantum (NISQ) hardware due to noise and decoherence.
  • Efficient data encoding for quantum machine learning is a prerequisite for robust empirical studies and can be addressed separately from the search for quantum advantage in classification.
