Superposition is one of the most iconic concepts in quantum physics. The principle says that the particles such as electrons can exist in multiple positions simultaneously. For example, imagine a coin tossed in the air—it is not in a definite state of heads or tails while in the air until it is observed. Similarly, sub-atomic particles in quantum superposition exist in all possible states until they are measured.

The process of encrypting data is called cryptography. It converts plain text into scrambled text so that someone with the right “key” can read it. Quantum cryptography, by extension, uses the principles of quantum mechanics to encrypt data and transmit it securely.

If you haven't realized this already, your grade 12 chapters on optics and light is more like a history review than a physics course. I say this because one never reaches the interpretation of light and its duality until towards the end of the book.

In quantum mechanics, the phenomenon of quantum entanglement stands out as both perplexing and fascinating. It is one of the iconic principles of quantum physics and probably the bedrock of new-age quantum technologies.

Quantum tunnelling is one of the most intriguing phenomena in quantum physics. Tunnelling may appear to have little relevance to everyday life but it is a fundamental process of nature that is responsible for many things on which life itself is dependent.

The landscape of digital security is constantly evolving and threats loom large. But, the emergence of quantum security provides hope. Quantum security represents a paradigm shift in the way we safeguard our digital infrastructure against increasingly sophisticated attacks.

At the core of quantum mechanics is the idea that particles, such as electrons and photons, can exist in multiple states simultaneously. Unlike classical physics, where an object can only exist in one state at a time, quantum superposition allows particles to exist in a combination of states.

In cybersecurity, where data protection is paramount, traditional cryptographic methods have long been the stalwart guardians of sensitive information. However, as computing power advances, so too do the tools available to potential attackers. In the ever-evolving landscape, the emergence of quantum cryptography offers a promising solution to the challenges of secure communication in the digital age.

We are witnessing the second quantum revolution. We are, for the first time, exploring the possible applications of quantum superposition and quantum entanglement. Quantum communication is one of the important use cases of quantum mechanics. Building a large and fully-functional quantum network will determine the commercial success of quantum communication.

In computer science and technology, the term “quantum computing” has emerged as a buzzword, capturing the imagination of scientists, engineers, and enthusiasts alike. But what exactly is a quantum computer, and how does it differ from classical computers?

Quantum computing uses fundamental principles of quantum mechanics to perform complex processing. Quantum cryptography leverages the same principles for advanced data encryption. However, quantum computing and quantum cryptography are not allies. Instead, they stand tall against each other at the crossroads!

Before understanding Quantum Key Distribution (QKD), let us understand quantum cryptography. Cryptography is the process of encrypting and protecting data such that only the person with the right secret key can decrypt it. Quantum cryptography is a process of encryption using properties of quantum mechanics to transmit data securely, making it hack-proof.
