I don’t know why they are surprised at this. There has been experiment after experiment showing this. I know many scientists have been in denial and have claimed for some time that entanglement would not allow faster than light information travel but it does. There has also been some very good experiments using entangled photons in remote scanning where two beams of photons are used. The one beam of entangled photons are used to scan a target while the other is directed to a sensor and from the resultant information of the second beam only there has been some success generating an image.
I wouldn’t be surprised if a crude quantum semaphore system couldn’t be devised to show clearly that information can be transmitted faster than the speed of light.
The article says the photons are “entangled” which means they are connected in some fashion.
The best analogy I can some up with is to imagine a 2 x 4 of infinite length. (we’ll ignore mass and rigidity in this example) If you move the 2 x 4, at any point along the length, it will communicate motion almost instantaneously. However, it won’t violate the laws governing the speed of light, even though a million miles away, it will be moving at the same time as the other end. Obviously, in this instance, distance matters. Two feet away won’t gain you anything. 200,000,000,000 feet away, though.....
