标题： Quantum Diffusion Models

摘要： 我们提出了一种生成扩散模型的量子版本。 在此算法中，人工神经网络被参数化量子电路所取代，以便直接生成量子态。 我们展示了该算法的完整量子版本和潜在量子版本；我们还展示了这些模型的条件版本。 这些模型的性能已通过定量指标和定性评估进行评估。 已经在一个简化的算法版本上在真实的NISQ量子硬件上进行了实现。 显示英文摘要

摘要： We propose a quantum version of a generative diffusion model. In this algorithm, artificial neural networks are replaced with parameterized quantum circuits, in order to directly generate quantum states. We present both a full quantum and a latent quantum version of the algorithm; we also present a conditioned version of these models. The models' performances have been evaluated using quantitative metrics complemented by qualitative assessments. An implementation of a simplified version of the algorithm has been executed on real NISQ quantum hardware.
