Definition
Quantum mechanics is a branch of physics that deals with the behavior of particles at the atomic and subatomic level, where classical physics fails to explain their properties accurately.
The concept that particles can exhibit both wave-like and particle-like behavior.
Superposition: The ability of quantum systems to exist in multiple states simultaneously.
Entanglement: A phenomenon where two or more particles become correlated in such a way that their states are linked, regardless of the distance between them.
