QuDDPM Introduces Efficient Generative Learning For Quantum Data

Researchers led by Quntao Zhuang publish a preprint (arXiv v5, 30 Jan 2026) proposing the quantum denoising diffusion probabilistic model (QuDDPM) to train generative quantum models. QuDDPM uses expressive circuit layers and intermediate denoising tasks to avoid barren plateaus, provides learning-error bounds, and demonstrates learning of correlated quantum noise, many-body phases, and topological quantum data.
