Abstract - This paper explores the foundations of quantum computing, delving into the principles of quantum mechanics and their application in quantum gate operations. Furthermore, it investigates quantum key distribution protocols, such as the BB84 and E91 protocols, which leverage quantum properties to establish secure communication channels. The paper also examines various cyber- attacks that pose threats to quantum communication systems, including man-in-the-middle attacks and brute-force attacks. The paper proposes a system enhanced by Quantum Key Distribution (QKD), coupled with symmetric encryption algorithms like AES-128, to ensure the confidentiality and integrity of transmitted data. Additionally, the paper presents a literature survey, summarizing recent advancements and challenges in the field of quantum computing and cryptography, emphasizing the importance of quantum key distribution in bolstering communication security.
