Data security is one of the most important and challenging issues in the digital age. With the increasing threats of cyberattacks, hacking, and espionage, the need for secure and reliable encryption methods is paramount. However, most of the current encryption methods rely on mathematical algorithms that can be broken by powerful computers, especially quantum computers. Quantum computers are machines that use the principles of quantum physics to perform computations that are impossible or extremely difficult for classical computers. They have the potential to solve problems that are beyond the reach of current cryptography, such as factoring large numbers or finding discrete logarithms. This poses a serious threat to the security of data that is encrypted using these methods. Quantum cryptography is a science that applies quantum mechanics principles to data encryption and data transmission so that data cannot be accessed by hackers – even by those malicious actors that have quantum co
