Quantum Key Distribution (QKD) — Basic

A small project demonstrating Quantum Key Distribution concepts and simulations using Qiskit. It includes examples of QKD protocols and classical post-processing to produce shared secret keys that can be used with a Vernam cipher (one‑time pad).

QKD protocols

• BB84
• B92
• E91

Current Features

• Entanglement examples and circuit construction for E91-style experiments
• Classical post-processing: basis reconciliation and key sifting
• Visualization of states and measurement histograms
• Simple Vernam cipher (one‑time pad) encryption/decryption using generated keys

Quick start

1. Create and activate a Python virtual environment.
2. Install dependencies from requirements.txt.
3. Run the notebook(s) to simulate circuits and generate keys.
