Explore Wave-Particle Duality with expert insights, use cases, and solutions. Learn how Wave-Particle Duality can enhance your cybersecurity and protect sensitive data.

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.

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.

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.

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.

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.

To comprehend the concept of a qubit, one must first grasp the essence of quantum computing. Unlike classical computers, which operate based on binary bits—units of information—quantum computers harness the peculiar phenomena of superposition and entanglement to process data in a fundamentally different manner.

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!

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.

Quantum computing (QC) garners a lot of positive press due to its power to solve complex computations several times faster. It is envisioned that QC can be a critical enabler and a strong catalyst to considerably reduce the computational power required to perform complex calculations and boost the future of sixth-generation (6G) communication.

Explore the quantum electrodynamics (QED) behind photon creation, where charged particles like electrons emit photons during quantum transitions between energy eigenstates, governed by Fermi’s Golden Rule and interaction Hamiltonian matrix elements.

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 live in an information age where digital communication has become a lifeline for our businesses. Optical fibres are the backbone of our modern information networks. Long-range communication over the internet and high-speed information transfer within data centres take place over optical fibres.

The past few years have seen a rise in IoT technologies. We can connect everyday objects—kitchen appliances, cars, thermostats, baby monitors—to the internet via embedded devices for seamless communication between people, processes, and devices.

Companies and governments around the world are in a race to build the first usable quantum computer. The technology promises to make some kinds of computing problems much, much easier to solve than with today’s classical computers, but it also poses a significant threat to the integrity of encrypted data.

A quantum computer is a computing technology that uses sub-atomic particles and the principles of quantum mechanics to perform exponentially faster computations than existing computers. Quantum computing has many applications in healthcare, such as protein folding. However, the technology also has the power to break today’s encryption protocols that secure data and critical systems.

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.

Standard cryptography protects almost everything in our lives, including our personal email and banking, businesses, government entities, the health industry, and public infrastructures. As our world has become increasingly digitised, our exposure to something that can break said cryptography can pronounce disaster if it falls into the wrong hands.

The Signal Protocol is a set of cryptographic specifications that provides end-to-end encryption for private communications exchanged daily by billions of people around the world. The team announced on their blog that they are upgrading the X3DH specification to PQXDH, a first step in advancing quantum resistance in the Signal protocol.

Most of us remember Y2K. The global Y2K project aimed to replace the two-digit year codes with four-digit codes by December 31, 1999, to ensure that computers didn’t think the year was 1900 and bring the world to a halt. We successfully navigated the problem. At the tick of 00:00:01 on January 1, 2000, the world functioned as usual.

The whole world is reeling from one of the worst pandemics ever seen. Health systems of most countries are under stress, and in a few countries have crumbled from the sheer size of the population infected by a fast-spreading disease. People with low immunity and comorbidities are the worst impacted.
