The rise of quantum computers poses a huge risk to current encryption methods and security protocols. The paper discusses whether Quantum Key Distribution (QKD) can be a useful tool in strengthening the current and existing cryptography methods and provide more robust security against both classical and quantum computers. The research was conducted by analyzing the functioning of a quantum computer and the existing methods of encryption that are currently in use. An in-depth study looking at the strengths and weaknesses of three different QKD protocols- BB84, B92 and E91 was conducted. A python program was created to simulate the three QKD protocols and their efficiency in different noise environments. The analysis shows how QKD methods have significantly evolved over the years and provide strong and comprehensive security systems and methods of encryption that are immune to quantum computers. QKD will be a key component in developing and strengthening encryption methods that are currently used by a vast majority of people. The rise of quantum computers poses a significant threat to current encryption methods. By implementing QKD protocols, encryption and security will be greatly boosted, safeguarding sensitive data and maintaining users' privacy. Although QKD has many advantages and great potential to strengthen encryption, there are many obstacles that are yet to be overcome such as hardware constraints, high quantum costs, and vulnerability to certain attacks. The study also touches upon the need for improvement =s in scalable quantum hardware, error correction, and noise reduction. Additionally, the study looks at the potential of hybrid solutions that combine classical and quantum encryption techniques which may provide the most practical and easy to implement way to keep personal information secure in the quantum age.
