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.
