della teoria quantistica dell’informazione.
Intuition from our everyday lives gives rise to the belief that information exchanged between remote parties is carried by physical particles. Surprisingly, in a recent theoretical study [Salih H, et al. (2013) Phys. Rev. Lett. 110:170502], quantum mechanics was found to allows for communication even without the actual transmission of physical particles. From the viewpoint of communication, this mystery stems from a (non-intuitive) fundamental concept in quantum mechanics — wave-particle duality. All particles can be described fully by wave functions. To determine whether light appears in a channel, one refers to the amplitude of its wave function. However, in counterfactual communication, information is carried by the phase part of the wave function. Using a single-photon source, we experimentally demonstrate the counterfactual commu- nication and successfully transfer a monochrome bitmap from one location to another by employing a nested version of the quantum Zeno effect.
