Quantum Phase Estimation
1. What Is Quantum Phase Estimation (QPE)? Imagine you’re trying to unlock a digital safe, but the combination is hidden in the rhythm of a light blinking. You can’t see….
Quantum Fourier Transform
1. What Is the Fourier Transform (Intuition First)? Before diving into the quantum version, let’s first understand the basic idea of a Fourier Transform. Imagine you’re listening to music. Although….
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….
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….
