Quantum Brush Unlocks Novel Art with Four Quantum Algorithms on Current Devices

Digital painting enters a new era with the development of Quantum Brush, a tool that leverages the power of quantum computing to create unique artistic effects. João S. Ferreira, Arianna Crippa, and Astryd Park, alongside their colleagues, introduce a system that translates brushstrokes into quantum algorithms, opening up possibilities for aesthetics previously unattainable with traditional methods. This innovative approach explores how quantum phenomena can directly influence artistic expression, offering painters a palette of effects governed by the laws of quantum mechanics. Importantly, the team demonstrates the feasibility of this technology on existing quantum hardware, executing the algorithms on IQM’s Sirius device and paving the way for a future where quantum computers become a creative tool for artists.

Quantum Computing Enhances Digital Painting Techniques

Quantum Brush is a new tool that explores how quantum computing can enhance digital painting, moving beyond traditional methods that struggle to replicate the subtleties of artistic techniques. Current digital painting software simulates brushstrokes and colour mixing using algorithms limited by the complexities of light-matter interaction and colour perception, whereas quantum computing offers a fundamentally different approach, exploiting principles like superposition and entanglement to unlock new creative possibilities for artists and designers. This work introduces Quantum Brush, a novel digital painting tool based on quantum computing principles, aiming to demonstrate how quantum algorithms can enhance the realism and expressiveness of digital painting by simulating brushstroke dynamics, colour mixing, and light transport. The tool provides a platform for artistic experimentation, enabling the creation of digital paintings with unprecedented levels of detail and nuance.

The project delivers four distinct digital brushes, Aquarela, Heisenbrush, Smudge, and Collage, each translating brushstrokes into unique quantum processes rooted in established physical principles and compatible with current quantum hardware. Experiments demonstrate the potential of these brushes to produce unexpected results and offer new avenues for artistic inspiration, potentially offering advantages over machine learning approaches which can be limited by training data. The team acknowledges that this work is a first step, and future development will focus on expanding the range of quantum effects available within the tool and evaluating them on diverse quantum processing units. Further enhancements include interactive colour palettes and differently shaped brushes to allow artists greater control over the quantum-native colour space, with potential extensions into areas like structure and composition, particularly within virtual reality environments. The open-source nature of Quantum Brush encourages collaboration between artists and scientists, fostering further exploration of quantum mechanics as a source of artistic innovation.
