12 Lecture Notes - Lecture 1: Quantum Entanglement
Document Summary
Quantum physics, also known as quantum mechanics, is a branch of physics that deals with the behaviour of matter and energy on the scale of atoms and subatomic particles. Unlike classical physics, which is based on the laws of motion and gravity that govern the behaviour of macroscopic objects, quantum physics describes the strange and counterintuitive behaviour of particles on the quantum scale. One of the fundamental principles of quantum physics is the wave-particle duality, which states that particles such as electrons and photons can display both wave-like and particle-like behaviour. This means that a particle can be described as both a wave with a definite wavelength and frequency, and as a particle with a definite position and momentum. Another important concept in quantum physics is the uncertainty principle, which states that the position and momentum of a particle cannot both be precisely measured at the same time.
