QuForge: a library for qudit simulation

QuForge v0.3.5

QuForge is a Python-based quantum simulator designed for qudits, extending quantum computing capabilities beyond traditional qubits. It facilitates the simulation of quantum circuits with customizable qudit dimensions, supporting both dense and sparse operations for efficient computation. Built on the differentiable framework PyTorch, QuForge enables execution on accelerating devices such as GPUs and TPUs, enhancing simulation speed.

Installation

Install QuForge using pip:

pip install quforge

To install the latest version directly from the source:

# Clone the repository
git clone https://github.com/tiago939/QuForge.git

# Navigate to the project directory
cd QuForge

# Install the package
pip install .

Ensure that your environment meets the necessary dependencies listed in requirements.txt.

Usage

Here's an example of how to create and execute a simple quantum circuit using QuForge:

import quforge.quforge as qf

# Initialize a 2-level (qubit) circuit with 2 wires
circuit = qf.Circuit(dim=2, wires=2)

# Add gates to the circuit
circuit.H(index=[0])           # Hadamard gate on wire 0
circuit.CNOT(index=[0, 1])   # CNOT gate with control wire 0 and target wire 1

# Initialize the state
state = qf.State('0-0', dim=2)

# Execute the circuit
result = circuit(state)

print(result)

This script sets up a quantum circuit with a Hadamard gate and a CNOT gate, then executes it on an initial state.
