Digital vs. Analog Quantum Simulations
Simulating quantum systems is one of the most promising applications of quantum computing. Quantum simulation allows scientists to model complex quantum behavior in materials, molecules, and high-energy physics — all….
Trapped Ion Qubits
Trapped ion qubits are individual atoms that are used as the basic units of quantum information — called qubits. These atoms are held in place (or “trapped”) using electric and….
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….
Quantum Gates and Circuits
In classical computing, we use circuits made from logic gates like AND, OR, and NOT to process information using bits (which are either 0 or 1). Quantum computing is similar….
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 challenges of scaling quantum computers
Quantum computing promises to revolutionize problem-solving in fields like cryptography, drug discovery, AI, and materials science. However, despite rapid advancements, today’s quantum computers remain small-scale prototypes with limited real-world applications…..
