What This Software Does

This repository contains a comprehensive collection of quantum computing algorithms implemented using Qiskit for IBM Quantum hardware. The project demonstrates various quantum computing concepts with practical implementations across fundamental algorithms, search optimization, quantum transforms, cryptographic communication protocols, and error correction methods.
The algorithms are organized into several categories including Deutsch, Deutsch-Jozsa, Bernstein-Vazirani algorithms for function problems, Grover’s algorithm for unstructured search, QAOA for combinatorial problems, Quantum Fourier Transform (QFT), Quantum Phase Estimation (QPE), BB84 and E91 quantum key distribution protocols, quantum teleportation, and VQE for molecular ground states.
Each algorithm implementation includes both Python scripts for execution on real IBM Quantum hardware and OpenQASM circuit files for visual execution in the IBM Quantum Composer. The project provides hands-on learning experiences for quantum computing concepts with access to actual quantum processors through IBM’s free tier quantum service.
