+**Quantum effects** describe the peculiar behaviors of matter and energy at the smallest scales, where the classical rules of physics break down. Here, particles can exist in multiple states simultaneously, a phenomenon known as [superposition](/wiki/superposition), or become mysteriously linked, even across vast distances, as described by [quantum mechanics](/wiki/quantum_mechanics).
