Ghost imaging is like a game of Battleship. Instead of seeing an object directly, scientists use entangled photons to remove the background and reveal its silhouette. This method can be used to study ...

Researchers from the University of Twente, in the Netherlands, say that they have gained “important insights” into photons, which “behave in an amazingly greater variety than electrons surrounding ...
