"Researchers at the University of Rochester have made an optics breakthrough that allows them to encode an entire image's worth of data into a photon, slow the image down for storage, and then retrieve the image intact."
The quantum-mechanics explanation of how they stored the image on the photon is actually quite simple - they shone a single photon through a stencil, which as a wave passed through the entire stencil at once, presumably in a non-deterministic fashion. What I'm curious about is how the information was decoded from the photon back into an image. It seems like attempting to "read" the data from the photon would cause the possible places in the stencil that the photon passed through into one certain location on the stencil, therefore only revealing a single point in the image. But then, my understanding of this subject is pedestrian at best.
Anyway. Science is awesome.
