+# Quantum Brush — Effects & Brushes Reference
+
+A guide to every brush effect available in Quantum Brush, including the quantum principles behind each one, their parameters, and credits to the original authors.
+
+> All effects are part of the [Quantum Brush](https://github.com/moth-quantum/QuantumBrush) project by [MOTH Quantum](https://github.com/moth-quantum).

+
+## 1. Basic (Acrylic)
+
+| | |
+|---|---|
+| **Author** | MOTH |
+| **Version** | 1.0.0 |
+| **Source** | [`python/acrylic/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum?** | No — classical brush baseline |
+
+A simple, uniform-color painting brush that serves as the non-quantum baseline. Paints a consistent color with configurable opacity and optional feathered edges.
+
+**Parameters:**
+- **Radius** — Brush size (0–100)
+- **Color** — Base color of the brush
+- **Alpha** — Opacity (0.0–1.0)
+- **Blur Edges** — Smooth feathered edges vs. hard edges
+
+---
+
+## 2. Smudge (Damping)
+
+| | |
+|---|---|
+| **Author** | Joao |
+| **Version** | 1.0.0 |
+| **Source** | [`python/damping/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Pumping/Damping quantum channels |
+| **Dependencies** | Qiskit |
+
+Mixes colors on the canvas using quantum amplitude damping and pumping channels. Each stroke segment is encoded as a qubit state (mapping HLS color values to Bloch sphere angles), then evolved through controlled rotation gates that simulate energy exchange with an ancilla qubit. The resulting expectation values are decoded back into shifted HLS colors.
+
+**Parameters:**
+- **Radius** — Brush size (0–100)
+- **Strength** — How strongly colors are mixed (0.0–1.0)
+- **Invert Luminosity** — Reverses the damping direction (light-first vs. dark-first)
+
+---
+
+## 3. Collage (Clone)
+
+| | |
+|---|---|
+| **Author** | Joao |
+| **Version** | 1.0.0 |
+| **Source** | [`python/clone/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Asymmetric Universal Quantum Cloning |
+| **Dependencies** | Qiskit |
+
+Copies and pastes regions of an image subject to the no-cloning theorem of quantum mechanics. The selected region's pixel data is decomposed via SVD, and the singular values are encoded as qubit angles. An asymmetric universal cloning circuit (using a state-preparation gate and CNOT cascade) produces two imperfect copies — the quality trade-off between copy and paste fidelity is controlled by the Strength parameter. At Strength = 0.66, it achieves the symmetric cloning bound.
+
+**Parameters:**
+- **Strength** — Copy vs. paste fidelity trade-off (0.0–1.0)
+ - `1.0` = perfect copy, zero paste fidelity
+ - `0.0` = perfect paste, zero copy fidelity
+ - `0.66` = symmetric (balanced) case
+

+
+## 4. Aquarela (QDrop)
+
+| | |
+|---|---|
+| **Author** | Joao |
+| **Version** | 1.0.0 |
+| **Source** | [`python/qdrop/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Entanglement-driven color mixing |
+| **Dependencies** | Qiskit |
+
+A watercolor-style brush that mixes a target color with the existing canvas colors using quantum entanglement. The stroke is split into discrete drops, each encoded as qubit states. Controlled rotations entangle each drop with an ancilla qubit, steering the color towards the target. The entanglement creates non-classical correlations between drops, producing organic color variations impossible with simple blending.
+
+**Parameters:**
+- **Number of Drops** — Resolution of the effect (2–15)
+- **Radius** — Brush size (0–100)
+- **Strength** — Effect intensity (0.0–1.0)
+- **Target Color** — Base watercolor color
+
+---
+
+## 5. Heisenbrush (Continuous)
+
+| | |
+|---|---|
+| **Author** | Arianna |
+| **Version** | 1.0.0 |
+| **Source** | [`python/heisenbrush/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Heisenberg spin model time evolution |
+| **Dependencies** | Qiskit, Qiskit Aer |
+
+Simulates how quantum spins evolve in the Heisenberg model to produce smooth, evolving color shifts along a stroke. The user's selected color is converted to spherical angles on the Bloch sphere, and each path segment becomes part of a simulated chain of qubits. The Heisenberg Hamiltonian (XX + YY + ZZ interactions with external Z and X fields) drives time evolution via Trotterized circuits. Mean magnetization is measured at each time step via the Estimator primitive and mapped back to HLS color shifts.
+
+**Parameters:**
+- **Radius** — Brush size and number of qubits in the simulation (1–100)
+- **Strength** — Blend between base color and quantum-generated colors (0.0–1.0)
+- **Color** — Initial state of the quantum evolution
+
+---
+
+## 6. Heisenbrush (Discrete)
+
+| | |
+|---|---|
+| **Author** | Arianna |
+| **Version** | 1.0.0 |
+| **Source** | [`python/heisenbrush2/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Heisenberg spin model (discrete multi-stroke variant) |
+| **Dependencies** | Qiskit, Qiskit Aer |
+
+The discrete variant of the Heisenbrush. Instead of one continuous stroke, the user draws multiple separate strokes (up to 10), and each stroke segment independently evolves through the Heisenberg model. Each segment produces its own quantum-derived color, giving the brushwork a visibly discrete, physics-inspired variation. Uses the same underlying Heisenberg time-evolution circuit as the continuous version.
+
+**Parameters:**
+- **Radius** — Brush size and qubit count (1–100)
+- **Strength** — Quantum vs. base color blend (0.0–1.0)
+- **Color** — Initial quantum state color
+
+---
+
+## 7. Game of Life (GoL)
+
+| | |
+|---|---|
+| **Author** | Daniel |
+| **Version** | 1.0.0 |
+| **Source** | [`python/GoL/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Quantum Cellular Automata (nearest-neighbour) |
+| **Dependencies** | Qiskit, Qiskit Aer |
+
+Implements a quantum cellular automaton inspired by Conway's Game of Life. Each pixel's HSV color is encoded as a qubit state on the Bloch sphere. For each pixel, a 9-qubit circuit is constructed from its 3x3 neighbourhood, applying controlled rotations (CRX, CRY, CRZ, CX) to simulate neighbour interactions. The central qubit's reduced density matrix is extracted via partial trace, and the closest pure state determines the new color. A semi-classical Game of Life rule (SCGOL) governs the third color channel. Supports lasso mode (Radius = 0) for region-based application.
+
+**Parameters:**
+- **Iterations** — Number of cellular automata steps (1–10)
+- **Mapping** — Which HSV channels map to which GoL function (0–5)
+ - `0: hsv`, `1: hvs`, `2: shv`, `3: svh`, `4: vhs`, `5: vsh`
+- **Radius** — Brush width; 0 = lasso mode (0–100)
+
+---
+
+## 8. Chemical
+
+| | |
+|---|---|
+| **Authors** | Luminists — Ali, Henrique Ennes & Jui-Ting Lu |
+| **Version** | 1.0.0 |
+| **Source** | [`python/chemical/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Variational Quantum Eigensolver (VQE) for molecular simulation |
+| **Dependencies** | Qiskit (>=2.1.0), SciPy |
+
+Uses intermediate steps of the VQE algorithm from quantum chemistry to modify canvas colors. Pre-computed VQE circuits for H2 molecule simulation are loaded from stored QPY files. The stroke is split into segments matching the number of available circuits. Each segment's average color is encoded as qubit angles, the VQE circuit is applied, and Pauli expectation values are measured to compute new angles. The result maps the physical process of molecular ground-state energy optimization onto visual color transformations.
+
+**Parameters:**
+- **Radius** — Brush size (0–100)
+- **Bond Distance** — Simulated interatomic distance in Angstroms (0.735–2.5)
+- **Number of Repeats** — How many times each circuit is applied before moving to the next (1–100)
+
+---
+
+## 9. Quantum Pointillism
+
+| | |
+|---|---|
+| **Authors** | Khrystian Koci & Benjamin Thomas |
+| **Version** | 0.2.0 |
+| **Source** | [`python/pointillism/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Ising model many-body interactions |
+| **Dependencies** | Qiskit, SciPy |
+
+A pointillism brush that places dots along the stroke path with quantum-correlated colors. Dots are sampled using Poisson disk sampling with exponential distance bias from the path. Each dot's color is encoded as a qubit, and neighbouring dots interact through an Ising Hamiltonian (H = -J sum Z_i Z_j - h sum X_i). Trotterized time evolution creates quantum correlations between nearby dots. Positive coupling produces similar neighbor colors (ferromagnetic); negative coupling produces contrasting neighbors (antiferromagnetic). Falls back to classical blending for >25 dots.
+
+**Parameters:**
+- **Dot Count** — Number of dots to place (10–200)
+- **Coupling Strength** — Ising coupling J (-1.0 to 1.0)
+- **Evolution Time** — Quantum evolution duration (0.1–10.0)
+- **Target Color** — External field color
+- **Dot Size** — Radius of each dot (1–20)
+- **Color Variance** — Random noise level for organic variation (0.0–1.0)
+
+---
+
+## 10. Steerable
+
+| | |
+|---|---|
+| **Authors** | Luminists — Chih-Kang Huang & Jui-Ting Lu |
+| **Version** | 1.0.0 |
+| **Source** | [`python/steerable/`](https://github.com/moth-quantum/QuantumBrush/tree/source) |
+| **Quantum Principle** | Quantum geometric control theory |
+| **Dependencies** | Qiskit, PennyLane, JAX |
+
+Applies quantum control theory to steer one image region's colors toward another. The user selects source and target regions via lasso, and pixel data is decomposed via SVD into normalized quantum state vectors. A PennyLane quantum circuit is trained (using JAX-based optimization) to find the unitary transformation that evolves the source state toward the target state. The learned transformation is then applied to a paste region. The time parameter `t` controls how far along the transformation the system evolves, with `t > 1` producing extrapolated effects beyond the target.
+
+**Parameters:**
+- **Controls** — Number of qubits / feature dimensions (2–4)
+- **timesteps** — Discrete time steps for circuit evolution (10–100)
+- **t** — Evolution time parameter (0.0–1.2)
+- **Source = Paste** — Apply effect in-place or define a separate paste region
+- **Show source & target** — Visualize selection outlines
+- **show color** — Outline color for visualization
+- **show thickness** — Outline width (1–20)

+# Issue #32 Fulfillment — [Refactoring] Improve UX/UI of the App with Code Implementation
+
+> Reference: https://github.com/moth-quantum/QuantumBrush/issues/32
+
+This document outlines how the Electron + React rewrite of Quantum Brush addresses every requirement from Issue #32.
+
+---
+
+## 1. (10 pts) Improve Window Arrangement & UI/UX Workflow
+
+**Problem:** The original Java app scattered its interface across three separate windows (Control Panel, Canvas, Stroke Manager), making the workflow confusing and cluttered.
+
+**Solution:** The rewrite consolidates everything into a **single, responsive Electron window** (default 1400x900, min 900x600) with a clean layout:
+
+| Region | Position | Width | Purpose |
+|---|---|---|---|
+| Sidebar | Left | 56px fixed | Tool selection, import/export, project actions |
+| Canvas | Center | Flexible (`flex-1`) | Fabric.js drawing surface with zoom/pan |
+| Control Panel | Right | 320px fixed | Brush settings, effect selector, dynamic parameters |
+| Stroke Manager | Bottom overlay | Full width, 192px | Collapsible stroke history drawer |
+| Title Bar | Top | Full width, 32px | Project name and file path display |
+
+**Key improvements over the original:**
+- All panels live within one window — no scattered floating dialogs
+- The canvas fills all available space and is fully responsive to any screen size
+- The Stroke Manager sits as a collapsible bottom drawer, accessible but out of the way
+- Flexbox-based layout adapts cleanly across Windows, macOS, and Linux
+- Space+drag panning and scroll-wheel zoom provide smooth canvas navigation
+- Keyboard shortcuts (V/B/E/D for tools, Ctrl+Z/Y for undo/redo, Ctrl+S to save) streamline the workflow
+
+**Relevant files:**
+- `src/App.tsx` — Root layout composition
+- `src/components/CanvasArea.tsx` — Responsive canvas with zoom/pan
+- `src/components/Sidebar.tsx` — Left toolbar
+- `src/components/ControlPanel.tsx` — Right panel
+- `src/components/StrokeManager.tsx` — Bottom drawer
+
+---
+
+## 2. (10 pts) Improve the JSON Communication System
+
+**Problem:** The original app used a cumbersome JSON document exchange between Java and Python, making graphical execution slow and inconvenient.
+
+**Solution:** The rewrite implements a structured IPC pipeline with SVG support:
+
+```
+React UI → IPC (contextBridge) → Electron Main Process → Python subprocess → PNG + JSON files
+```
+
+**How it works:**
+1. The canvas state is serialized as a **PNG data URL** and saved to disk
+2. An **instruction JSON** file is written with all parameters:
+ ```json
+ {
+ "effect_id": "heisenbrush",
+ "stroke_id": "stroke_1234",
+ "project_id": "proj_5678",
+ "user_input": { "Radius": 5, "Strength": 0.5, "Color": "#FF0000" },
+ "stroke_input": {
+ "path": [[x1, y1], [x2, y2]],
+ "clicks": [[cx, cy]]
+ }
+ }
+ ```
+3. Python is spawned as a subprocess with a 3-minute timeout
+4. Python reads the instruction, runs the effect, produces an output PNG (diff mask — only changed pixels)
+5. The output is returned to the renderer as a base64 data URL and composited on the canvas
+
+**SVG support:**
+- Stroke paths are archived as SVG files per-stroke via `saveStrokeSvg()`
+- Full SVG import/export is supported through native file dialogs (`importSvg` / `exportSvg`)
+- SVG data is generated from Fabric.js path objects, providing a clean vector representation of user strokes
+
+**Relevant files:**
+- `electron/main.ts` — IPC handler registration
+- `electron/preload.ts` — Typed contextBridge API
+- `electron/python.ts` — Python subprocess spawner, JSON/PNG/SVG I/O
+- `python/apply_effect.py` — Python entry point for effect execution
+
+---
+
+## 3. (20 pts) New Design Language
+
+**Problem:** The original app used Java Swing's default look, making it feel like software from the early 2010s.
+
+**Solution:** A complete modern design system built with **Tailwind CSS v4**, documented in `design/DESIGN_SPEC.md`:
+
+### Color Palette
+| Layer | Tailwind Class | Hex |
+|---|---|---|
+| App background | `bg-gray-950` | `#0a0a0f` |
+| Panel background | `bg-gray-900/80` | `rgba(17,24,39,0.8)` |
+| Surface/Input | `bg-gray-800/80` | `rgba(31,41,55,0.8)` |
+| Borders | `border-white/10` | `rgba(255,255,255,0.1)` |
+| Primary accent | `bg-blue-600` | `#2563eb` |
+| Active glow | `shadow-blue-600/30` | `rgba(37,99,235,0.3)` |
+
+### Design Principles
+- **Dark mode only** — optimized for creative work and reduced eye strain
+- **Glassmorphism** — panels use `backdrop-blur-xl` with semi-transparent backgrounds for depth
+- **Inter font family** — clean, modern typography with system fallbacks
+- **Lucide React icons** — consistent, lightweight icon set throughout the UI
+- **Thin scrollbars** — minimal visual noise
+- **Toast notifications** — slide-in animations for feedback (success/error/info)
+- **Cross-platform consistency** — looks great on Windows, macOS, and Linux
+
+**Relevant files:**
+- `design/DESIGN_SPEC.md` — Full design specification
+- `src/index.css` — Global styles, font, color scheme, animations
+- `tailwind.config.js` — Tailwind configuration
+
+---
+
+## 4. (60 pts) Full Desktop Application Implementation
+
+**Problem:** The original Java + Processing stack was limiting for modern graphical software development.
+
+**Solution:** A complete rewrite using a modern tech stack:
+
+### Tech Stack
+| Technology | Role |
+|---|---|
+| **Electron** | Cross-platform desktop shell |
+| **React 18** | UI framework |
+| **TypeScript** | Type-safe development |
+| **Vite** | Fast bundler with HMR |
+| **Fabric.js v7** | HTML5 canvas engine |
+| **Tailwind CSS v4** | Utility-first styling |
+| **Zustand** | Lightweight state management |
+| **electron-builder** | Packaging for macOS (.dmg), Windows (NSIS), Linux (AppImage) |
+
+### Basic Features Implemented
+
+#### Creating a New Project
+- `ProjectDialog.tsx` provides a modal with project name, canvas width, and height inputs
+- Projects are stored internally with metadata at `project/{id}/metadata.json`
+- Each project gets its own `stroke/` subdirectory for effect data
+
+#### Importing an Image
+- Native file dialog via `ipcRenderer.importImage()` (PNG, JPEG, GIF, BMP, WebP)
+- Drag-and-drop support via `react-dropzone` (accepts `image/*` and `.svg`)
+- Images are scaled to fit the canvas and inserted at layer index 0 (behind strokes)
+- SVG import also supported via `ipcRenderer.importSvg()`
+
+#### Drawing on the Canvas
+| Tool | Description |
+|---|---|
+| **Brush** | Free-drawing with `PencilBrush`, configurable color/width/opacity |
+| **Eraser** | Manual hit-test removal of objects under cursor |
+| **Dot** | Single-click circle placement for point-based effects |
+| **Select** | Native Fabric.js selection with delete/backspace support |
+
+Additional canvas features:
+- Scroll-wheel zoom (0.1x to 20x)
+- Space+drag panning
+- Full undo/redo stack (20 states)
+
+#### Saving for Execution
+- **Internal save:** Canvas state serialized via `canvas.toJSON()` and stored in project directory
+- **File save:** `.qbrush` file format (versioned JSON wrapper around canvas state)
+- **Export:** PNG and SVG export via native Save dialogs
+- **Effect execution:** One-click "Apply Effect" button runs the Python backend with all stroke/parameter data
+
+#### Effect Plugin System
+Effects are dynamically discovered from `python/{effectId}/` directories, each containing:
+- `{effectId}_requirements.json` — schema defining name, description, parameters, and input types
+- `{effectId}.py` — Python implementation with `run(req) -> np.ndarray`
+
+Available effects include: `acrylic`, `chemical`, `clone`, `damping`, `GoL`, `heisenbrush`, `heisenbrush2`, `pointillism`, `qdrop`, `steerable`.
+
+The Control Panel dynamically generates parameter controls (sliders, color pickers, toggles) based on each effect's requirements JSON.
+
+### Cross-Platform Distribution
+Configured via `electron-builder.json5`:
+- **macOS:** `.dmg` installer
+- **Windows:** NSIS installer (x64)
+- **Linux:** AppImage
+
+**Relevant files:**
+- `electron/main.ts` — Electron window, menus, IPC handlers
+- `electron/preload.ts` — Secure contextBridge API

-# Welcome to the source code of Quantum Brush!
-
-Writer: Astryd Park
-
-## Technical Description
-
-Quantum Brush is a standalone Java application with `Processing (Java)` framework and `conda` environment's `Python 3.11+` as its backend. It's built with `OpenJDK`:
-
-``` bash
-(base) astrydpark@Astryds-MacBook-Pro ~ % java -version
- openjdk version "21.0.7" 2025-04-15 LTS
- OpenJDK Runtime Environment Temurin-21.0.7+6 (build 21.0.7+6-LTS)
- OpenJDK 64-Bit Server VM Temurin-21.0.7+6 (build 21.0.7+6-LTS, mixed mode, sharing)
-```
-
-After clone this repository, you can edit the code and build an app from scratch to test your contribution. Using [`Eclipse IDE`](https://eclipseide.org/) is highly recommended. I used `2025-03` version.
-
-## One more thing before setting up the IDE
-
-To set up the devleopment environment easily, I recommend go to [the `dist` branch](https://github.com/moth-quantum/QuantumBrush/tree/dist) of the repository and install the app on your system. Follow the instructions there! Then, the installer script will install `miniconda3` and the `conda` environment with all required Python libraries, including `openJDK`.
-
-*c.f.* After that and the instructions below, when you build the app for the first time, you might see the error regarding Python configuration. It's fine, just go to the `Tools` > `Python Configuration` menu on the menu bar of Quantum Brush. Select the Python file underneath your `conda` instllation path (most of the time, it's underneath `$HOME/miniconda3/envs/{yourEnvironment}/bin/python3.x`).
-
-
-
-Select the file, save the changes, and you won't see any errors afterwards.
-
-## Build the project from scratch
-
-To make the source code as an executable Java project in Eclipse IDE, create a new Java project in your ideal location.
-
-After you download Eclipse IDE, underneath your `$HOME` folder, you can see there is a folder named `eclipse-workspace`. This is the easiest place to start but you can choose any directory as a workplace. In my case, I choose the easiest option, and made the folder called `Test` inside `eclipse-workspace`.
-
-
-
-After that, you will see the fresh window like this.
-
-
-
-Let's create a Java project. If you put a cursor on 'File', you can select the option.
-
-
-
-Set the project name as `QuantumBrush` (why not?), **uncheck `Use default location`** and choose **the cloned repository path** from Browse. *Uncheck `Create module-info.java file` too*. Press `Finish`.

-
-Press `src` on Package Explorer and press the green 'GO' button.

- c.f. (For advanced users) For some reason, if you really, really want to bring only .java files to some folder that you want to work on...
-
-To make the source code as an executable Java project in Eclipse IDE, two main steps are required. One is adding Processing 4's core library, which is shipped with its license and the source code in this repository, to the project's build path. The other is import the source codes from `src` folder into the IDE. Since Eclipse IDE doesn't naturally recognise the collection of `.java` files as a Java project, you need to follow the instructions.
-
-### Step 1: Let's make these raw Java files recognisable as a Java project.
-
-After you download Eclipse IDE, underneath your `$HOME` folder, you can see there is a folder named `eclipse-workspace`. This is the easiest place to start but you can choose any directory as a workplace. In my case, I choose the easiest option, and made the folder called `Test` inside `eclipse-workspace`.
-
-
-
-After that, you will see the fresh window like this.

-
-
-Set the project name as `QuantumBrush` (why not?), uncheck `Use default location` and choose `src` folder from the cloned repository. Uncheck `Create module-info.java file` too. Press `Finish`.
-
-
-
-
-
-After that, you can see the Java project is created based on the source code. But there's an issue. You would witness that there are so many red warnings. It's because the project doesn't know where to reference to get Processing (Java) framework.
-
-### Step 2: Let's make Processing 4 recognisable as a reference.
-
-If you open up the Package Explorer, you can see underneath `QuantumBrush`, there's `default package`, and if you open it up, you can see the source code (`.java` codes).
-
-Oh, and don't forget to download Processing 4 from its [official website](https://processing.org/download).
-
-- Hard way: Now, browse through this path on the Finder window: `Applications/Processing/Contents/app/resources/core/library/core-4.4.1.jar`. To find the `Contents` on the Applications window, right-click the `Processing` icon, and select `Show Package Contents`.
-- Shortcut for you: You can actually reference the `lib` folder in the cloned repository, and copy the `core-4.4.1.jar` file from there.
-
-
-
-Press `cmd + c` to copy the core JAR file. After that, go back to Eclipse, `cmd + v` to paste the file on the `Package Explorer` window after click `QuantumBrush`.
-
-
-
-Now, right-click the `core-4.4.1.jar` and select `Build Path` > `Add to Build Path`.
-
-And that's pretty much it! Now you can build the Java project.

+# Quantum Brush
+
+A modern, open-source desktop application for quantum-powered digital art. Quantum Brush lets you paint with brushes driven by real quantum computing algorithms — from Heisenberg spin models to quantum cellular automata — producing visual effects that are impossible with classical computation alone.
+
+This project is a complete rewrite of the original [Quantum Brush](https://github.com/moth-quantum/QuantumBrush) by [MOTH Quantum](https://github.com/moth-quantum), rebuilt from the ground up with a modern tech stack while preserving and extending the original quantum effect engine.
