Researchers have been able to encode an image into a photon and to later retrieve it intact. It’s analogous to the difference between snapping a picture with a single pixel and doing it with a camera — this is like a 6-megapixel camera… You can have a tremendous amount of information in a pulse of light, but normally if you try to buffer it, you can lose much of that information… We’re showing it’s possible to pull out an enormous amount of information with an extremely high signal-to-noise ratio even with very low light levels
