Quantum mechanics is the study of matter and matter's interactions with energy on the scale of atomic and subatomic particles. By contrast, classical physics explains matter and energy only …

Quantum physics is the study of matter and energy at the most fundamental level. It aims to uncover the properties and behaviors of the very building blocks of nature.

This section contains video lectures for part 1 of the course.

Dec 18, 2025 · Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of …

Jul 26, 2025 · As quantum theory advanced, physicists began to see particles not as tiny billiard balls, but as excitations in quantum fields. Every type of particle—electron, quark, photon—is a …

An introduction to quantum physics with emphasis on topics at the frontiers of research, and developing understanding through exercise.

In this quantum physics introduction for beginners, we will explain quantum physics, also called quantum mechanics, in simple terms. Quantum physics is possibly the most fascinating part of …

We now come to engineered systems whose behaviour is fundamentally quantum mechanical, and in particular, to the ‘quantum devices’ which are expected to be the building blocks of a …

Mar 4, 2025 · Quantum physics is the foundation of much of the technology we use today, and its principles shape our understanding of the universe at the smallest scales. This article will …

Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) …
