This article aims to perform implementation tests of the E91 Protocol, a type of QKD (Quantum Key Distribution) protocol responsible for generating secret keys. These keys can be applied to cryptographic algorithms to guarantee information security in both quantum and classical environments. The quantum tests were conducted on the IBM-Q platform, and the classical tests were performed using Visual Studio Code. The primary objective of implementing this protocol in two different environments is to draw comparisons, highlighting the similarities between simulation and actual implementation. In real quantum environments, data transmission is susceptible to quantum phenomena and may contain noise, which compromises its execution. The simulation of the E91 quantum protocol and its implementation on the IBM-Q quantum platform demonstrated the protocol's functionality, including measurements, basis sharing, coincidence verification, calculation of the CHSH inequality, and key generation.

Quantum Key Distribution Using BB84 and E91 Protocols with QIS-Kit

The rapid advancement of quantum computing poses a significant threat to classical cryptographic systems that form the backbone of modern digital security.Algorithms such as RSA and ECC, which rely on the computational difficulty of integer factorization and discrete logarithm problems, become vulnerable to quantum attacks, particularly Shor's algorithm.This project presents a comprehensive Quantum Key Distribution (QKD) Simulator that implements the BB84 and E91 protocols using IBM's Qiskit quantum computing framework, providing an interactive platform for understanding, simulating, and analyzing quantum-safe key exchange mechanisms.The simulator features a full-stack architecture with a FastAPI backend powered by Python and Qiskit for quantum circuit execution, and a React 19 frontend with TypeScript for interactive visualization.The BB84 protocol implementation supports configurable qubit counts, multiple measurement bases (Z, X, and Diagonal), Eve's intercept-resend attack simulation with adjustable interception rates, and Quantum Bit Error Rate (QBER) calculation with a security threshold of 8.5%.The E91 protocol implementation uses entangled Bell state pairs with configurable measurement angles, CHSH inequality violation testing for quantum security verification, and reverse gate anti-eavesdropping mechanisms.Additionally, the system includes an AES encryption module that uses quantum-generated keys from BB84 and E91 simulations to perform AES-128, AES-192, and AES-256 encryption, with privacy amplification for keys shorter than the required length.A simulation history system with SQLite and PostgreSQL support enables experiment tracking, comparison, and analysis.The project demonstrates the practical application of quantum mechanics principles to cryptographic security and serves as an educational tool for understanding the transition from classical to quantum-safe cryptography.

Quantum Key Distribution (QKD) brings a revolutionary approach to secure communication by using the principles of quantum mechanics to safeguard the transfer of cryptographic keys.This project explores the practical deployment of two foundational QKD protocols: BB84 and E91.The BB84 protocol secures key distribution through photon polarization, while the E91 protocol uses the unique properties of quantum entanglement to enhance resistance to eavesdropping.By contrasting these quantum methods with classical cryptographic techniques, the study provides a comprehensive look at their relative strengths and limitations.Practical implementation and thorough analysis demonstrate that QKD protocols offer significant advantages in preventing interception, shedding light on their potential role in advancing cryptographic security in the era of quantum technology.This research not only assesses the practical challenges of implementing QKD but also considers future advancements that could broaden its real-world applications.
