So what is entanglement? Electrons have a quantum property called spin that makes them act like little magnets. We’ll always measure it pointing in one direction or the opposite: up or down, say. If we entangle two electrons so that their spins are always pointing in opposite directions, the two spins are said to be correlated. If we entangle the two electrons in this way – and fire them in opposite directions, we don’t know which one of the pair is up and which one is down until we make a measurement. If we find that electron 1 is spin up. We know the spin of electron 2 must be down. Why isn't this like a pair of gloves? The handedness of the gloves is there from the start. It never changes. With entangled particles that’s not the case. They are in a superposition. Prior to measurement, there is no definite answer. How do we know superposition is real? The double slit experiment is good evidence. Entangled particles are stranger, because a measurement on one particle determ
