Answer to Question #198470 in Quantum Mechanics for Marisa

Question

What is a proposed useful application of entanglement, which has been a dream of science fiction writers?

Answer 1

Well, there is no mane applications of entanglement in physics and science at all. Scientists in XX century were thinking about infinity fast transition of energy and information. This idea is named quantum teleportation in non-scientific world. But this idea was broken by the particular physic laws (conservation laws of physical values). Actually now, entanglement are fundament for protocols of quantum security methods.
