Chapter 12: Quantum Cryptography – Quantum Key Distribution
A few decades ago, cryptographic techniques were mainly used by governments and military forces to exchange messages during wartime when information was key. Now that huge amounts of data are transmitted over the internet, it has become crucial to design strong cryptographic algorithms to ensure data security and integrity.
To protect your private data, such as banking information and passwords, these algorithms typically use a key to transform it into unreadable scrambled text so that only someone who knows the key can decrypt it and access the information.
Classical cryptographic algorithms rely on the assumption that an attacker only has access to a limited power of computation, but the rise of quantum computing could break this assumption. This has led to the creation of quantum cryptographic techniques that make use of quantum mechanics to encrypt and decrypt data in order to design unhackable algorithms...
