Can you explain the basics of quantum mechanics in simple terms?

Quantum mechanics is a branch of physics that deals with particles and their interactions at the atomic level. It explains how atoms, molecules and other physical objects behave on an atomic and subatomic scale. At its core, it states that all matter has both wave-like and particle-like properties. This means that particles can exist in two places at once (such as being in two places simultaneously) and that they can also be in two different states at the same time (such as being both excited and unexcited). These phenomena are known as superposition and entanglement respectively.
