crowe-quantum-net 1.0.1

Quantum networking — channels, entanglement distribution, teleportation protocols

crowe-quantum-net

Quantum networking primitives — channels, entanglement sources, entanglement swapping, teleportation, and fidelity metrics.

Installation

pip install crowe-quantum-net

Features

• Quantum Channels: Depolarizing, amplitude damping, custom Kraus operators
• Entanglement Source: Pure Bell states and Werner (noisy) states
• Entanglement Swapping: Extend entanglement across network nodes
• Teleportation Protocol: Full Bell-measurement teleportation with Pauli corrections
• Metrics: Fidelity, concurrence, trace preservation checks

Quick Start

from crowe_quantum_net import (
    depolarizing_channel, EntanglementSource,
    TeleportationProtocol, concurrence
)
import numpy as np

# Teleport a qubit state
proto = TeleportationProtocol()
state = np.array([0.6, 0.8], dtype=complex)  # arbitrary qubit
result = proto.run(state)
print(f"Fidelity: {result.fidelity:.4f}")  # ~1.0

# Measure entanglement
source = EntanglementSource(fidelity=0.95)
dm = source.generate_density_matrix()
print(f"Concurrence: {concurrence(dm):.4f}")
