- Built quantum bit generation and measurement simulation
- Created eavesdropping detection mechanisms with statistical analysis
- Developed error correction and privacy amplification algorithms
- Added visualization of quantum states and measurement outcomes
Results
- Successfully demonstrated secure key exchange over simulated quantum channel
- Achieved 99.5% key security with proper error correction
- Implemented efficient eavesdropping detection with 95% accuracy
- Created educational framework for understanding quantum cryptography principles
