Quantum superposition or quantum entanglement concept illustration. Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured. Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently.
