MOTH Unveils Quantum Brush features four distinct brushes, Aquarela, Heisenbrush, Smudge brush, and Collage: A New Era for Digital Art Driven by Quantum Algorithms
Quantum Brush, a cutting-edge open-source digital painting tool that uses quantum computing to create original artistic expressions, has been formally introduced by MOTH, a business that specializes in quantum technology. By examining how quantum effects can create distinctive aesthetics, this innovative program opens up new possibilities for art, media, and generative design by translating artists’ brushstrokes into distinctive quantum algorithms.
Oil paints, photography, and machine learning are examples of technology innovations that have continuously increased artistic possibilities throughout history. In keeping with this tradition, Quantum Brush raises the intriguing query: Is there such a thing as a quantum aesthetic or artistic style? Quantum Brush seeks to “make the invisible visible,” enabling artists to work with the “strange and beautiful mathematics of the quantum world” without requiring a thorough understanding of quantum mechanics, according to João Ferreira, a researcher at MOTH and one of the paper’s authors.

Four Brushes, Four Quantum Realities
Four separate brushes, Aquarela, Heisenbrush, Smudge, and Collage, are included in the original Quantum Brush release, each of which focuses on a different way that quantum phenomena might affect visual results. These brushes have been successfully implemented on IQM’s Sirius device and are compatible with existing noisy intermediate-scale quantum (NISQ) devices. Natural hardware noise from these devices is purposefully included to provide a particular quantum aspect and contribute to the unique, non-reproducible visual outputs.
Aquarela Brush
Aquarela: Entangled Colors and Fluid Blends
The Aquarela brush, which was inspired by translucent watercolor paintings, produces a blending effect in which colors get intertwined rather than merely combined. Every painted line turns into a quantum interaction, and the brush’s impact is contingent upon the canvas’s current state as well as its course. Subtle and original color shifts result from the brush and canvas communicating with one another through this quantum logic. The impact of intrinsic noise was demonstrated, for example, by applying Aquarela on Paul Cézanne’s 1895 self-portrait, which revealed distinctive color convergences (such as between green and red tones) on real hardware that were not seen in noiseless simulations.
Heisenbrush
Heisenbrush: Visualizing Quantum Dynamics
The Heisenbrush uses the simulated temporal evolution of quantum observables to create visual patterns. Its expressive capacity is derived from the behavior of quantum systems evolving under specified quantum time evolutions, rather than from classical randomness. Artists can engage with the invisible mathematical structure of quantum systems and transfer the development of quantum physics into visual expression.
As seen in Robert Delaunay’s “L’homme à la tulipe,” the brush blends in well with striking color schemes, producing strokes that, by virtue of entanglement, superposition, and non-classical evolution, create a dynamic conversation with the original artwork. With color changes linked to the magnetization of a one-dimensional spin-1/2 Heisenberg model, it provides both discrete (each stroke is a time step) and continuous (single stroke split into time steps) variants.
Smudge Brush
Smudge Brush: Exploring Quantum Information Erasure
The Smudge brush investigates the creation of new, entangled colors using information erasure techniques in quantum systems. In an effort to remove color information, the brush creates a new entangled colors that are passed to the remainder of the stroke as it progresses. In order to maximize expressivity and flexibility in a version of Henri Matisse’s “L’escargot,” Smudge was utilized to construct shapes with novel, highly entangled colors.
As a result of dephasing noise, Smudge, which ran on the Sirius device, frequently created darker colors (dark browns and greens), but it also displayed bright greens that weren’t seen in simulations. Only the brush tip undergoes pure dissipation in an uneven quantum cascade, which is caused by an ancilla qubit applying an amplitude damping/pumping channel.

Collage Brush
Collage: Navigating the No-Cloning Theorem
The no-cloning theorem, which asserts that an unknown quantum state cannot be precisely replicated without collapsing the original, is a basic constraint of quantum mechanics that is visualized by the Collage brush. Collage must weigh the information lost from the original image against the integrity of the new copy when trying to replicate a portion of it. The brush encodes the RGB content into a single qubit by letting users choose a “copy” region and a “paste” location.
After that, it performs an incomplete copy using a universal asymmetric quantum cloning (UAQC) procedure. Collage showed how technique may produce serial art motifs with different levels of authenticity when applied to Alfons Maria Mucha’s “Les Saisons,” mostly changing internal color correlations while maintaining structural elements. However, as demonstrated by the notable color discrepancies between simulations and real device runs, Collage is extremely sensitive to noise because of an exponentiation step.
Designed for Artists, Open to All
Quantum Brush is made available as an open-source, stand-alone program. Artists may import photos, choose brushes and parameters, and create strokes using its user interface, which is similar to that of traditional image editing software. On quantum devices, strokes are controlled by a “Stroke Manager” that facilitates parallel execution. After quantum processing is finished, only updated pixels are applied, and a snapshot of the canvas is saved. This enables artists to experiment with the stochasticity of quantum computing and re-execute strokes.
Importantly, the tool maps hue and luminosity to the spherical angles (ϕ, θ) of a single-qubit state by encoding color information using the HSL (hue, saturation, luminosity) paradigm. While overcoming the difficulties of mapping colors to quantum states, this “quantum-native, NISQ-compatible” method guarantees creative control.
Early partner Roman Lipski, an artist based in Berlin, characterized his encounter as a “dialogue” with the instrument. The Quantum Brush offered a workflow that alternated between exploration and control, challenging long-standing habits and inspiring new creative avenues with its strange behaviors and transformations. He pointed out that while other brushes enhanced details, Collage allowed for more extensive changes, and a pressure-sensitive tablet proved crucial for precise control.
A New Medium for Exploration
The first step towards a potent tool that uses quantum-mechanical principles to produce new, invisible visual art is offered by Quantum Brush. With the team anticipating possible future applications in fields like visual effects, generative media, and immersive experiences like virtual reality, the research adds to the expanding nexus between quantum science and artistic expression.
In order to promote a collaborative movement in quantum aesthetics where art and quantum physics come together, MOTH invites scientists, artists, and “dreamers alike” to submit their own brushes, algorithms, and ideas to the open-source initiative. This project aims to give digital art a human touch while bringing the abstract beauty of quantum processes to life.
