Gravitational Wave Detection via Atomic Vapor Cells: A Quantum Simulation and Deep Learning Framework

Python 3.8+ QuTiP 4.7+ PyTorch 2.0+ License: MIT GitHub Stars DOI


📋 Table of Contents


📋 Overview

FusionWareAlttex is a comprehensive open-source framework for theoretical modeling and simulation-based analysis of ultra-weak space-time perturbations in atomic vapor systems. This project investigates the quantum response of rubidium (Rb) atomic vapor cells to gravitational wave-induced strain perturbations, combining advanced quantum simulation techniques with state-of-the-art deep learning architectures.

The framework provides a complete pipeline from first-principles quantum modeling through synthetic dataset generation to real-time AI-powered signal detection and classification, with optional integration with LIGO/Virgo gravitational wave observatory data.
