| contents | <p class="MsoNormal"><span>Quantum entanglement is a non-classical correlation between quantum systems that cannot be accounted for by any local hidden-variable theory. Since its articulation in the Einstein-Podolsky-Rosen paper of 1935 and its formal testability through Bell's theorem in 1964, entanglement has evolved from a philosophical puzzle into the central resource of quantum information science. This review surveys the conceptual foundations of entanglement, the experimental record culminating in loophole-free Bell tests, and applications including quantum key distribution, quantum teleportation, and measurement-based quantum computation. We summarise quantitative results of representative Bell experiments, discuss entanglement measures for mixed states, and outline recent developments in long-distance entanglement distribution via satellites and quantum repeaters. Persistent challenges decoherence, certification of high-dimensional entanglement, and scalable distribution are identified as active frontiers of research.</span></p> |
