A Python Package for Quantum Key Distribution

QKDpy: Quantum Key Distribution Library

QKDpy is a comprehensive Python library for Quantum Key Distribution (QKD) simulations, implementing various QKD protocols, quantum simulators, and cryptographic tools. It provides an intuitive API similar to NumPy, TensorFlow, and scikit-learn, making quantum cryptography accessible to developers and researchers.

Features

• Quantum Simulation: Simulate qubits, quantum gates, and measurements
• QKD Protocols: Implementations of BB84, E91, SARG04, and more
• Key Management: Error correction and privacy amplification algorithms
• Cryptographic Tools: One-time pad encryption and authentication using quantum keys
• Visualization: Tools to visualize quantum states and protocol execution
• Extensible Design: Easy to add new protocols and features
• Performance: Efficient implementations for simulations

Installation

QKDpy requires Python 3.10 or higher. We recommend using uv for package management:

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone the repository
git clone https://github.com/yourusername/qkdpy.git
cd qkdpy

# Install in development mode
uv pip install -e .

Quick Start

Here's a simple example of using the BB84 protocol to generate a secure key:

from qkdpy import BB84, QuantumChannel

# Create a quantum channel with some noise
channel = QuantumChannel(loss=0.1, noise_model='depolarizing', noise_level=0.05)

# Create a BB84 protocol instance
bb84 = BB84(channel, key_length=100)

# Execute the protocol
results = bb84.execute()

# Print the results
print(f"Generated key: {results['final_key']}")
print(f"QBER: {results['qber']:.4f}")
print(f"Is secure: {results['is_secure']}")
