Spooky Physics: Quantum Mechanics can Mimic an Influence of Future Actions on Past Events

Spooky Physics: Quantum Mechanics can Mimic an Influence of Future Actions on Past Events: Physicists at the Institute for Quantum Optics and Quantum Information, the University of Vienna, and the Vienna Center for Quantum Science and Technology have demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist.
