correlation between measurements of quantum subsystems, even when spatially separated
Quantum entanglement is a phenomenon where two or more particles become connected in such a way that measurements of one particle instantly relate to measurements of the other, even when they're far apart. This matters because it challenges our everyday intuitions about how the world works and has practical applications in emerging technologies like quantum computing and secure communication.

Spontaneous parametric down-conversion process can split photons into type II photon pairs with mutually perpendicular polarization.
Quantum entanglement is the phenomenon in which the quantum state of each particle in a group cannot be described independently of the state of the others, even when the particles are separated by a large distance. The topic of quantum entanglement is at the heart of the disparity between classical physics and quantum physics: entanglement is a primary feature of quantum mechanics not present in classical mechanics.
