Quantum Algorithms for Solving PDEs
1. Introduction to PDEs Partial Differential Equations (PDEs) are foundational in modeling dynamic systems that evolve over time and space. They are used extensively across fields such as physics (wave….
Cryptanalysis
Cryptanalysis is the study of analyzing and breaking cryptographic systems—decoding encrypted data without access to the secret key. It’s a cornerstone of cybersecurity, helping test the strength of encryption methods….
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….
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….
