恒元物理学讲座（第104期）：Counterfactual communication: Optical communication with invisible photons

讲座内容：It has long been assumed in physics that for information to travelbetween two parties in empty space, physical particles have to travel betweenthem. Here, using the ‘‘chained’’ quantum Zeno effect, we show how informationcan be transferred between the two parties without any physical particlestraveling between them.
