About This Project

A full-stack web application that simulates quantum computing operations, demonstrating qubit state transformations through quantum gates and probabilistic measurement outcomes. The simulator models fundamental quantum mechanics concepts including superposition, measurement collapse, and probability distributions.

Technical Stack

Backend: Python, FastAPI, SQLAlchemy, PostgreSQL with Stored Functions

Frontend: Jinja2 Templates, Vanilla JavaScript, CSS3

Data Visualization: Matplotlib for measurement histograms

Deployment: Railway (Hobby), Neon (PostgreSQL)

Architecture: MVC pattern with usecase layer for business logic separation

Quantum Computing Concepts

Qubit States: Complex amplitude representation (α|0⟩ + β|1⟩) with normalization validation
Quantum Gates: Unitary transformations (Pauli-X/Y/Z, Hadamard, Identity) via matrix operations
Measurement: Probabilistic collapse to basis states based on |α|² and |β|²
Superposition: Visualization of measurement outcome distributions
