qNetVO: The Quantum Network Variational Optimizer

Simulate and optimize quantum communication networks using quantum computers.

Features

QNetVO simulates quantum communication networks on differentiable quantum cicuits. The cicuit parameters are optimized with respect to a cost function using automatic differentiation and gradient descent. QNetVO is powered by PennyLane, an open-source framework for cross-platform quantum machine learning.

Simulating Quantum Communication Networks:

• Construct complex quantum network ansatzes from generic quantum circuit compenents.
• Simulate the quantum network on a quantum computer or classical simulator.

Optimizing Quantum Communication Networks:

• Use our library of network-oriented cost functions or create your own.
• Gradient descent methods for tuning quantum network ansatz settings to minimize the cost.

Quick Start
