Many-Body Physics Simulations
In the realm of quantum mechanics, a “many-body” system refers to a group of multiple interacting particles, such as electrons in a solid or atoms in a gas. Unlike single-particle….

Quantum Networks
Imagine a future where information flows not just at lightning speed but also with absolute security, where computers on different continents operate in perfect quantum sync, and where scientific experiments….
Entanglement Swapping
Before diving into entanglement swapping, it’s important to understand quantum entanglement. Entanglement is a unique quantum phenomenon where two or more particles become connected in such a way that the….
Quantum Teleportation
Quantum teleportation is one of the most fascinating phenomena in quantum mechanics. Despite the science-fiction name, it doesn’t involve transporting matter or people from one place to another. Instead, it….
E91 Protocol
The E91 Protocol is a Quantum Key Distribution (QKD) method proposed by physicist Artur Ekert in 1991. It was a significant development in quantum cryptography because it uses quantum entanglement….
Spin Qubits
Spin qubits are a type of quantum bit (qubit) where information is stored in the quantum property known as “spin” of particles such as electrons or atomic nuclei. In the….
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….
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….
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….
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….
