Variational Quantum Brushes
- 基于变分量子算法构建两种新绘画工具：可调控型与化学模拟型。
- 可调控型通过量子几何控制融合两幅艺术作品，化学型模拟分子基态能量演化色彩。
- 开源实现兼容原版量子画笔，适合量子艺术与生成模型研究者使用。
量子画笔是费雷拉等人（2025）提出的利用量子行为生成新颖艺术效果的计算艺术软件。本文作为科普论文，介绍了两种基于变分量子算法的量子画笔——可调控型与化学型的数学框架与实现方法。可调控型利用量子几何控制理论融合两幅艺术作品；化学型模仿变分本征求解器，用于估算分子基态能量，从而在底图上演化颜色。两种画笔的实现均已开源，发布于 https://github.com/moth-quantum/QuantumBrush，且完全兼容原始量子画笔系统。
原文摘要 · Abstract (English)
Quantum brushes are computational arts software introduced by Ferreira et al (2025) that leverage quantum behavior to generate novel artistic effects. In this outreach paper, we introduce the mathematical framework and describe the implementation of two quantum brushes based on variational quantum algorithms, Steerable and Chemical. While Steerable uses quantum geometric control theory to merge two works of art, Chemical mimics variational eigensolvers for estimating molecular ground energies to evolve colors on an underlying canvas. The implementation of both brushes is available open-source at https://github.com/moth-quantum/QuantumBrush and is fully compatible with the original quantum brushes.
