Mu-DisCoCat: A Variational Pipeline for Compositional Generalization on Quantum Processors

Mu-DisCoCat is a multimodal variational quantum learning framework that maps Compositional Distributional Semantics (DisCoCat) onto Variational Quantum Circuits (VQCs) to achieve compositional concept generalization (CoCoGen). The pipeline first learns stable object representations from single-object image-text pairs, then fixes these to learn relations in multi-object scenarios. In classical simulations it outperformed a CLIP baseline on out‑of‑distribution relational accuracy, and on noisy quantum emulators and real IBM and IQM hardware it maintained strong fidelity correlations, reliably distinguishing unseen similar and dissimilar pairs.

Evolving Hybrid Quantum-Classical Architectures for Image Classification

The paper presents an evolutionary framework, EXAQC, that automatically discovers parameterized quantum circuits (PQCs) for use as intermediate modules in hybrid quantum‑classical neural networks for image classification. By evolving PQCs while keeping classical feature‑extraction and prediction layers fixed, the authors achieve high accuracies on MNIST, Fashion‑MNIST, and CIFAR‑10 with gate counts comparable to other quantum architecture‑search methods. The evolved hybrid models match or exceed the performance of classical networks while using far fewer trainable parameters, and the choice of encoding (rotation‑based vs amplitude) significantly impacts accuracy.

Quantum MeanFlow: single-shot generative sampling on NISQ hardware

Quantum MeanFlow (QMF) is a new quantum generative sampling method that enables single‑step sample generation by learning an average velocity field over a time interval, unlike the multi‑step quantum flow matching (QFM) which requires sequential integration of an ordinary differential equation. Using parameterized quantum circuits, the authors benchmark QMF and QFM on the MNIST dataset, finding that QMF produces lower image quality than multi‑step QFM but outperforms single‑step QFM at every shot count. Both models were executed on IBM quantum computers, and best‑of‑N rejection sampling mitigates device noise without circuit modification, demonstrating QMF’s practicality for efficient single‑step quantum generative sampling.
