Quantum Walk Algorithms
Quantum Walk Algorithms are quantum versions of random walks, which are processes that involve taking steps from one point to another in a randomized way — like flipping a coin….

Simon’s Algorithm
Simon’s Algorithm is a quantum algorithm that solves a very specific type of problem exponentially faster than any classical algorithm can. It was proposed by Daniel Simon in 1994 and….
Deutsch-Jozsa Algorithm
1. What Is the Deutsch-Jozsa Algorithm? The Deutsch-Jozsa algorithm is one of the earliest examples of how quantum computing can outperform classical computing — and it does so dramatically. It….
Grover’s Search Algorithm
1. What Problem Does Grover’s Algorithm Solve? Imagine you have a locked box with 1 million keys. Only one key opens it, but they all look identical. On a classical….
Shor’s Factoring Algorithm
1. The Big Problem It Solves At the heart of modern digital security (like online banking) is a method called RSA encryption. It relies on a simple idea: This “factoring….
Quantum Algorithms
1. What is a Quantum Algorithm? A quantum algorithm is a set of instructions designed to run on a quantum computer — using the unique principles of quantum mechanics like….
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….
Quantum Computing and Cryptography
Quantum computing is transforming the field of cryptography by introducing both threats and opportunities. While quantum computers promise unparalleled computational power, they also pose a major risk to traditional encryption….
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….
