An answer/comment on a sister site cited a paper that seems to have been published in a legitimate journal and seems to be claiming the possibility of communicating information via entanglement, which we should all know is not possible:
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, Li ZH, Al-Amri M, Zubairy MS (2013) Phys Rev Lett 110:170502], quantum mechanics was found to allow for communication, even without the actual transmission of physical particles. From the viewpoint of communication, this mystery stems from a (nonintuitive) 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 communication and successfully transfer a monochrome bitmap from one location to another by using a nested version of the quantum Zeno effect.
I haven't read the paper and don't really have time to devote to it, but since it seems to be an extraordinary claim, I'm outsourcing this to physics.SE for debunking (at least of the interpretation of the result; the paper is probably legitimate). Can any one summarize what the actual result is and how it's consistent with QM?
