hakeutumisilmiö
hakeutumisilmiö is the Finnish term for quantum entanglement, a nonclassical correlation between physical systems that arises when the quantum state of each system cannot be described independently of the state of the other(s). The phenomenon is characterised by the fact that measurements on one part of an entangled state instantaneously affect the outcome probabilities of measurements on the remaining parts, regardless of the spatial separation between them.
The concept was first formalised by Erwin Schrödinger in 1935 as a response to the Einstein–Podolsky–Rosen
Applications of hakeutumisilmiö are central to quantum information science, enabling protocols like quantum teleportation, superdense coding,
Experimental tests of the phenomenon, notably Bell‑inequality violations, have confirmed the nonlocal correlations predicted by quantum
