Vienna Center for Quantum Science and Technology – Zeilinger Group said:
In the new experiments, using a recently developed method pairs of entangled particles of light, called photons produced. One of the particles is selected such that a complex spatial pattern is formed when a large number of photons are absorbed by a highly sensitive camera - assuming that this will be triggered in each case at the right time. As a start signal for real-time recording, the second photon, which is detected in the conventional measuring apparatus is used. The shot with the camera photon has to travel only over 35 meters through a glass fiber before it is "photographed". Once there, the observed pattern, however, depends on exactly what happened with the first particle. "The setting of the measuring equipment for the first particle determines how the pattern looks, which leaves the second particle on the camera, despite the fact that the two instruments are that measure different photons that are clearly separated from each other independently," said Robert Fickler, author of the work. The start signal contains no information about how exactly the first photon was measured, and otherwise the camera does not receive any information about the settings of the other measuring apparatus. But nevertheless, the measured pattern of the camera depends on the previous measurement on the first photon from - exactly how quantum theory predicts it.
