Quantum Channel Visualization 🌀

This is an interactive web-based visualization tool for understanding how different types of quantum noise channels affect a qubit's Bloch sphere representation.

Built using HTML, CSS, JavaScript and Plotly.js for real-time 3D rendering.

🎯 Features

• Visualizes how quantum noise channels deform the Bloch sphere.
• Supports Bit Flip, Phase Flip, and Depolarizing channels.
• Slider to control the noise parameter p.
• Smooth animated transitions using Plotly.js.
• Intuitive UI for learning and teaching quantum information.

🧪 Quantum Channels Implemented

1. Bit Flip Channel
   Simulates noise that flips the qubit state from |0⟩ to |1⟩ or vice versa with probability p.

2. Phase Flip Channel
   Introduces a relative phase flip (Z gate-like error) with probability p.

3. Depolarizing Channel
   Randomly applies X, Y, or Z with equal probability p/3, shrinking the Bloch sphere.

🔮 Future Plans

Here are some ideas and features planned for future versions:

• ✅ Add more noise channels like:
  • Generalized Kraus Maps
• ✅ Mobile-friendly responsive design
• ✅ Add "Preset States" menu (e.g., |0⟩, |+⟩, |1⟩)
• ✅ Side panel showing the density matrix in real-time
• ✅ Add plots for Fidelity or Purity as a function of noise
• ✅ Create a blog post/tutorial explaining the theory behind the visualization
• ✅ Add educational tooltips or explanations for sliders & controls

Contributions are welcome!
