Quantum cryptography is a field of study that harnesses the principles of quantum mechanics to create secure communication channels. Unlike traditional cryptography methods that rely on mathematical algorithms, quantum cryptography uses the properties of quantum mechanics to protect sensitive information from being intercepted by eavesdroppers. But what are these properties of quantum mechanics that make quantum cryptography so secure?
To answer this question, we need to delve into the world of quantum mechanics. At the quantum level, particles behave in ways that are fundamentally different from what we observe in our daily lives. These particles can exist in multiple states at once, and their properties can change instantaneously based on the observation of a measurement. It is these properties, such as superposition and entanglement, that are utilized in quantum cryptography to create a secure communication channel that cannot be intercepted without being detected. In this article, we will explore these properties in more detail and how they are used to create secure communication channels in quantum cryptography.
What is Quantum Cryptography?
Quantum cryptography is a form of data encryption and security that uses the principles of quantum mechanics to protect sensitive information. It is a relatively new technology that is gaining popularity as it offers increased security against the ever-evolving techniques used by hackers to gain access to confidential data.
