Quantum Key Distribution (QKD)
Quantum Key Distribution (QKD) is a method of securely sharing secret keys between two parties using the principles of quantum mechanics. It allows two people—commonly called Alice and Bob—to communicate….

Quantum Memory Technologies
Quantum memory is a device or system that stores quantum information — typically in the form of qubits — for a period of time, just like classical memory stores bits…..
Photonic Quantum Computing
Photonic quantum computing uses particles of light, known as photons, to carry and process quantum information. Instead of using physical matter like electrons or ions, it harnesses the unique quantum….
Quantum Information Theory
1. What Is Information Theory? Before diving into the quantum part, let’s first understand the classical version. Information Theory, developed by Claude Shannon, is all about: In short, it answers:….
Superposition and Entanglement
Quantum mechanics is not just a new set of rules — it’s a whole new way of understanding reality. Two of its most mysterious and powerful ideas are superposition and….
Qubits and Quantum States
In classical computing, we rely on bits — tiny switches that are either off (0) or on (1). Every digital device you use operates using billions of these bits. But….
The race for quantum internet: Who will lead?
The world is on the verge of a new era of internet technology—one that is ultra-secure, ultra-fast, and powered by quantum mechanics. The quantum internet will enable unbreakable encryption, instantaneous….
Quantum communication: The next step in secure data transfer
In an era of increasing cyber threats and data breaches, traditional encryption methods face growing vulnerabilities, especially with the rise of quantum computing. Future quantum computers could potentially break current….
